Analysis on Countermeasures of Water and Soil Conservation and Eco-environment Construction in China

With economy development,human destruction of eco-environment is deteriorating,which has become a key treatment nationwide.What＇s more,eco-environment construction is proceeding and multi-eco-environment projects are developing.Water and soil conservation and eco-environment construction should be a strategic task long-term insisted on,which is a part of agricultural construction.The research analyzed the relationship between water and soil conservation with eco-environment,concluded the process of ecological civilization construction in promoting water and soil conservation,and proposed countermeasures,laying foundation for water and soil conservation and ecological construction.

Quantitative Appraisement on Ecological Carrying Capacity in Coastal Rapid Developing Region of Hainan Province

The ecological carrying capacity,an important indica- tor to evaluate the sustainable development of the ecosystem, means the potential ability of the natural ecosystem to carry so- cioeconomic development while the ecosystem is healthy.It is limited by the carrying capacity of natural resources and environ- ment and the elasticity of the ecosystem.It will be greatly signifi- cant to study the ecological carrying capacity of Hainan Province, the first ecological province admitted by the State Environmental Protection Administration in China.Not only is the natural eco- system reflected,but also the effects of human activities are em- phasized by integrating the ecosystem health analysis into the ecological carrying capacity research.The research results,using the Factor Analysis tools of software SPSS,indicate that the eco- logical carrying capacity of Hainan Province fluctuated obviously from 1996 to 2005.The level of the ecological carrying capacity of Hainan Province was relatively high in 1996,and reached into trough from 1997 to 1999.It has steadily ascended to be above the middle level since the 21st century.The results also show that policy factors,especially the implementation of the 'Ecological Province' strategy,were important driving forces to influence the ecological carrying capacity.With the population rapidly increas- ing,the land and water resources per capita have decreased quickly.The amount of the ecological carrying capacity was pro- moted remarkably by socioeconomic development especially economic growth and technology applications.All of these will provide useful suggestions to establish and enact regional devel- opment policies,especially for protecting and reconstructing the ecology and environment of Hainan Province.

Impacts of birdwatching tourism on environment and economy

Birdwatching tourism can be a good model for nature conservation and economic development if it is managed with the well-being of local ecosystems and human communities. Birdwatchers can bring financial sources to local nature conservation. Many communities and local leaders consider birdwatching as a significant mean to develop local economics and publicize regional image, but only few research have tried to study the impacts of relevant activities on destinations. The purpose of the paper is to give a comprehensive review on impacts of birdwatching from conservation economics and biology perspective. Use a behavioral approach study impacts of birdwatching tourism on environment and economy. Specific objectives here are: (1) review the value and significance on environment and economy; (2) economic potential of non-residential birdwatching for community-based conservations; (3) using a behavioral approach, combine quantitative and qualitative methods study birdwatching impacts; (4) outline the economic and environmental benefits and problems associated with the activity; and (5) aid community leaders and tourism business related company in their efforts to improving the value of birdwatching; help the leaders of natural reserve areas develop birdwatching tourism.

Quantitative evaluation of sustainable development based on ecological footprint method: a case study of Tianjin

Since the coneept of sustainable devetopment emerged in the late 1980s, more and more countries and regions have been utilizing sustainable development as their developing stratety. But decades have passed without any effective methods available to quantitatively assess sustainable development. Since the ecological footprint evaluation method initiated in 1992, it has become popular in quantitative assessment of sustainable development because of its convenience, easy-understanding, and rehability. As one of the biggest coastal cities in north China and the economic center of the Bohai Coastal Region, Tianjin＇s gross domestic product （GDP） was 369. 762 billion yuan in 2005, accounting for 2.0°of the whole nation＇s GDP. The paper analyzes Tianjin＇s development with the ecological footprint method, and the results show that Tianjin＇s ecoiogical footprint and biocapacity in 2005 were 2.507gha/cap and 0.2 76gha/cap respectively. The ecological deficit was 2.230gha/cap.And from 1980 to 2005,Tianjin＇s ecological deficit per 10^4 yuan GDP decreased;while per capita ecological deficit has been tending to increase rapidly in recent years.All these result demonstrate that Tianjin is in a state of unsustainable development.

Assessment of the Ecological Security in the Three Gorges Reservoir Area by Using the Ecological Footprint Method

The ecological footprint concept and its calculation models are useful for the measurement of the sustainable level of social and economic development.The ecological security situation of the Three Gorges Reservoir Area(TGRA) was evaluated using this concept in this study.The construction of the Three Gorges Reservoir has led to the change in the ecology and immigration status of TGRA.The ecological footprint method is an important means to study the regional ecological security.Our results suggested that,by excluding the areas for biodiversity conservation(12% of the total land),the ecological footprint per capita was 0.57895 ha,which exceeded the ecological carrying capacity in TGRA.The total ecological deficit was found to be 11,522,193.34 ha,accounting for 95.02% of the ecological carrying capacity.These findings suggested that the ecological security of TGRA was not good.In order to compensate for the ecological deficit,it was essential to introduce natural resources from other regions.

Land Use Changes of an Aeolian-Loessial Soil Area in Northwest China: Implications for Ecological Restoration

China has experienced dramatic land use changes over recent decades, with marked environmental and socio-economic consequences. Hengshan County, located in the aeolian-loessial area of Northwest China, was investigated to illustrate land use changes and their implications for environmental and long-term rural economic development. The farmland in Hengshan County significantly decreased during 1990–2003, whereas forest land and grassland increased. The conversion rates of farmland, orchard land, forest land and construction land varied markedly among different periods: 1990–1995, 1995–2000 and 2000–2003. Conversion of orchard land, grassland and construction land was dominant in 1990–1995, whereas the conversion of farmland to forest land mainly occurred in 2000–2003. The results suggested a profound transition in institutional policy and political economy of land management, including implementation of integrated soil erosion control projects, adoption of a market-oriented economy and the ‘Grain-for-Green’ policy, during this period in China. To achieve long-term sustainable land use in Hengshan County, efforts should aim at increasing off-farm income of rural families as well as establishing land-economizing mechanisms to promote land productivity, in addition to conservation measures.

Identifi cation of national priority areas for adaptation to climate change in China

The problem of global warming has been identif ied as the f irst in the list of the top ten environmental prob-lems in the world.As climate change will seriously affect the social and natural world that people live in,so it may lay serious repercussions on economic progress,social improvement,and sustainable development.International bodies everywhere and many of the countries' governments are responding urgently to this call.In recent years,climate change has affected different regions in China in different ways.In its national agenda,the Chinese government should address the problem of climate change and its negative impact on socio-economic development.In this endeavor the nation should introduce policies which will help its people and economy to adapt to these effects and changes.Priorityf ields of adaptation to climate change are the sensitive areas or departments which are more vulnerable to the negative influences of climate change.The negative impacts of climate change in some parts of China are considered to be very serious indeed as they affect the whole economy and community.As a result,priority should be given to these more affected regions for the limited state f inancing.This paper def ines adaptation and discusses the basic principles and programs in the identif ication of national priority areas where adaptation should be exercised.Based on the past studies,four priority areas in China are identif ied,namely,disaster prevention and mitigation,water resources,agriculture,and ecosystem.An analysis on the identifi cation procedures,and the reasons and tasks involved are given for each.

Rural community tourism in western Sichuan's Qiang nationality: a case study of Wulong Stockade

The importance of the local economy of the development of tourism resources in China＇s relatively underdeveloped minority areas is already common knowledge in academic and business circles. However it＇s necessary to research more on specific patterns of tourism development in these ethnic minority areas. This paper studies Wulong Stockade in Beichuan County in Sichuan Province and examines the distinctive experience of the local Qiang community about developing local tourism resources and the local funding of the development. It notes how the introduction of new re-afforestation laws of 1999 affected the traditional, agriculture-based economy and how a member of the communio： was a key motivator in initiating tourism as a new economic resource. It has also explored changes in the economic conditions of Qiang peasants since tourism began in Wulong Stockade, where local incomes have increased considerably. This paper focuses on a characteristic Qiang area in the mountains of western Sichuan, demonstrates the necessity and feasibility of community tourism development, and uggests that other ethnic minority mountain villages in rural areas draw lessons from Wulong Stockade＇s experience.

ENVIRONMENTAL SUSTAINABILITY AND SCENARIOS OF URBANIZATION IN ARID AREA——A Case Study in Wuwei City of Gansu Province

Based on data of questionnaire and field survey and two developing models of Business As Usual (BAU) and the Intensive Urbanization (IU), this article, taking Wuwei City, a medium size city and typical oasis arid area in Gansu Province with very vulnerable and sensitive natural environment but long history of oasis economy, as an example, evaluated the sustainability of its environment and analyzed the scenarios of Wuwei’s household energy consumption, waste discharge in transportation industry, primary industry, secondary industry, tertiary industry, by the integration of the systematical dynamics model Stella and Polestar language to simulate the future development of the research area. The results showed that, first, the developing model of IU was propitious to Wuwei City named for oasis economy and vulnerable natural environment. The strategy of "Intensive Urbanization" can change the structure of energy utilization, and improve the efficiency of energy utilization. Second, the proportion of domestic energy consumption will decrease with industrialization and economic development, while that of tertiary industry, secondary industry and transportation will gradually grow up according to strategy of "Intensive Urbanization". Third, the Wuwei City is facing a severe eco-environmental crisis under the conventional patterns of development and a better future under a sustainable urbanization scenario, in the next 10 to 20 years. The different developing trends were clarified and the relative countermeasures were put forward for the policy makers according to the driving forces.

An ecological risk assessment for heavy metals of the lead-zinc ore tailings

The structure of Pb,Zn,Cu and Cd in lead zinc ore tailing soils in Yongzhou,Hunan is analyzed by the optimized BCR sequential extraction procedure.The content and proportion of heavy metals of the mine are measured.Meanwhile,the ecological risks are evaluated with the Lars Hakanson＇s potential ecological risk exponential method.The analysis shows that the content of heavy metals is very high,reaching the level of serious pollution.The order of metal pollution degrees are Cd〉Pb〉Cu〉Zn.On the other hand,it is very possible that the heavy metals may combine together as compounds or cling to the crystal form of clay.Since the form of soluble acid and free metals are very little,it is not an easy job for metal elating or restoration of plants.Yet it is possible to take out those heavy metals adopting the chemical extraction technology.DTPA and EDTA,indicated by a research,both have iterative value and strong conformity effect.So they are effective elutriants to restore the polluted soil.A chemical extraction method is put forward in this paper.

Symbiosis Analysis on Industrial Ecological System

Industrial ecological system is a sustainable mode of modern industry development. Industrial symbiosis, a sub-field of industrial ecology, engages traditionally separate industries in a collective approach, involving exchange of materials, energy, water, and/or by-products, to enhance competitive ability and environmental performance. To construct a symbiosis analysis method, this article employs a number of parameters embodying information about materials, energy and economics as the main essential parameters in system analysis and introduces symbiosis profit and symbiotic consumption elements as the economic indicators. A modeling and simulation program is designed using the agent-based modeling approach to simulate the evolvement of a hypothetical coal-based industrial system and the change of symbiosis conditions in the process of construction is examined. The simulation program built using the Swarm library, which is a freely available multi-agent simulation package, provides a useful demonstration for the symbiosis analysis method.

Correlation Between Economic Development Level and Landscape Pattern in Beijing Peri-urban Areas

With the rapid changes of demographic and socio-economic structure, various ecological and environmental problems have emerged in peri-urban areas. Studies on the correlation between socio-economic development and eco-environmental preservation are inadequate. This paper analyzes the landscape pattern of peri-urban areas to address this issue. First, it studies the differentiation of economic development levels in Beijing peri-urban areas. Then, it explores the correlation between economic development level of each town and its landscape pattern using Pearson Correlation and grade difference indices. Furthermore, it summarizes the problems within current landscape pattern. Three conclusions are drawn from the analysis: (1) on the whole, the economic de- velopment level in Beijing peri-urban areas basically matches with landscape pattern; (2) landscape contagion degree decreases with the growth of economic development level in as much as 30% of Beijing peri-urban areas. This is an irrational phenomenon accord- ing to our judgment; (3) landscape fragmentation grades in more than half of the towns are higher than their economic development grades, suggesting that attention should be paid to excessive fragmentation of land use.

THOUGHTS ON CONSTRUCTING THE DEMONSTRATING AREAS OF THE ECOLOGICAL REBUILDING AND ECONOMIC SUSTAINABLE DEVELOPMENT IN HEXI REGION

Based on the field investigations, this paper analyzes systematically the achievements and problems of constructing the demonstrating areas of the ecological rebuilding and economic sustainable development in Hexi, Gansu Province, and then the thoughts on constructing the demonstrating areas are brought forward. It is considered that all kinds of ecological demonstrating areas should be merged in order to construct large scale characterized demonstrating areas which go beyond the district. In other words, in Hexi Region, Zhangye District should be constructed as the largest ecoagriculture demonstrating area of high technology; Wuwei District should be constructed as the largest ecological demonstrating area of agricultural comprehensive exploitation; JiuJia District, which is the shortened form of Jiuquan and Jiayuguan, should be constructed as the largest ecotourism demonstrating area; and Jinchang City should be constructed as the largest ecoindustry demonstrating area. At the same time, the constructing pattern should be selected according to the actual circumstances; science and technology should be applied to construct the demonstrating areas and accelerate the industrialization in the big market. Additionally, it is important to smooth the constructing system and implement the flexible and efficacious running mechanism, and it is suggested that the committee should be organized to administer the ecological demonstrating areas in Hexi Region.

Study on the Circular Agriculture Development in Beijing's Mountain Areas

Circular agriculture is an essential way to realize the positive recycling of ecology and harmonious development of the country construction.The sustainable development of Beijing's mountain areas depends on the background and orientation of ecological economy.Beijing's mountain areas bear the responsibility of protecting the ecological safety of the whole Beijing district and also the exploration of circular agriculture in mountain areas is very important to promote the sustainable use of agriculture resources.Beijing's mountain areas have possessed some practical experience in recycling agriculture development.Through summarizing the development mode and analyzing the development practice,the article puts forward three key segments of promoting Beijing circular agriculture development:strengthen propagate,develop superiority and built management mechanism.

Orientation and community participation of ecological development: a case study of Hutuo River in Shijiazhuang City,China

Entrusted to by Shijiazhuang municipal Party committee and government, Shanghai Tongji University fin- ished “The General Planning of Ecological Development Project of Hutuo River in Shijiazhuang City”. It aims to build Hutuo River into a wind-breaking and sand-fixing barrier and ecological protect district in the north of Shijiazhuang based on the recovery of natural ecology to improve the environment of Shijiazhuang city. It also intends to develop the district lightly and build it into a nature beauty spot and big park. After the construction for several years, the general environment of this district has been greatly improved. But during the development, the man-made landscapes are highlighted excessively, which deviates from the construction of nature landscape. The currency of constructing big leisure park gradually comes into being, so the recovery of nature ecological is slow. So, this paper intends to make the orientation to ecological development of Hutuo River in Shijiazhuang city and puts forward the community participation to promote the future development of ecotourism in Shijiazhuang.

A research of material input and environmental impact for Chinese economy:1990-2005

The process of economic activities is on the basis of tremendous material inputs.China has been discharging an enormous amount of waste,giving rise to a wide range of environmental impacts.The method of economy-wide material flow analysis(EW-MFA)is one of the effective tools to examine the flow of materials entering physical economies,and recognize early environmental problems.Relevant researches are still at the early stage in China and most focus on material throughput but are rarely concerned about the utilization of recycling resource and environmental impact.Based on more than 3,000 items of data related,materials entering Chinese economy are classified into three types,and then the characteristics of material input and environmental impact are presented for the years 1990-2005 by using the indicators derived from EW-MFA.The Ratio of Recycled Material(RRM) is added as the new indicator in order to be in accordance with the need of circular economy being promoted in China.Results show that the great changes in the structure of material input cause the continuous increase of industrial solid waste emissions and the bogging down of material productivity.The RRM reveals that the utilization of recycling resources remains at a fairly low level in China.Finally,some weakness of EW-MFA is discussed according to the calculated results.

Deliberative Democracy Establishment in Environmental Policies： alternatives for the Environmental Conflict Resolution

The environmental problems can not be addressed in all their depth and complexity, and the most viable solutions can be made only by direct and continuous reference to the large issues of the development of the society as a whole. Environment and economic development are indissoluble, the first is where we all live, and development is what we all do to improve our fate in this environment. A main cause is the attitude of economic operators towards the environment, an attitude according to which profit should be pursued immediately, while nature protection is left for later. Ecological crisis is a new phenomenon, but derived from anthropological crisis. This reflects, at a global level, man＇s inner crisis. Every man in part, and not people or humanity in general, is responsible for this crisis. Individual responsibility is not a question of quality, but a question of quantity. The ecological crisis is linked to the personal and social life of man as a whole. The convenience, lack of respect for things, irrational waste, lack of measure, irresponsibility, injustice, exploitation, winning dirty money, eudemonism, which manifest on all aspects of life and human activity, are factors that provoke it. And, unfortunately, they maintain it.

Research on the Development Model of Ecological Agriculture in Loess Hilly-Gully Region of Northern Shannxi, China

On the Loess Plateau of China, facing the vulnerable environment, local people have to try their best to guarantee the security of food, and at the same time, to control the most serious soil erosion in the world. The paper introduces two typical models of ecological agriculture: ecological agriculture with commodity and agri- culture with soil and water conservation. According to the local natural condition, the model of eco-agriculture with commodity could be characterized by the structure of “agriculture-byproduct”, “agriculture-fruit” or “agri- culture-forestry-husbandry”. The development of agriculture with soil and water conservation has decreased the soil erosion rate from 12,184 ton/km2 in 1980 to 458.4 ton/km2 in 1999, while the farmers’ income has increasingly risen. Analyses on the two models’ benefits both in terms of ecological and agricultural economy show that there is a great possibility to construct or restore good eco-environment with comprehensive control in the hilly-gully area of north Shannxi. Further more, the paper points out the potential problems of foodstuff production and stockbreeding development in forming ecological agriculture and eco-environmental restoration.
