Strategies for Prioritizing Ecological Construction with Consideration of Agricultural Industry Development in Northern China’s Agro- pastoral Ecotone : A Perspective of Opportunity Cost

In northern China’s agro-pastoral ecotone,there are conflicts between agricultural industry and ecological construction resource competition,and also problems urgently to be solved for economic growth and sustainable ecological improvement.Taking the development concept of"lucid waters and lush mountains being mountains of gold and silver"as the guiding principle of prioritizing ecological and green development,this paper studied the strategies for prioritizing ecological construction with consideration of economic development of agricultural industry from the perspective of opportunity cost.Through the analysis of opportunity cost,externality,and Pareto optimal theory,and using the calculation method of the unit equivalent factor value of terrestrial ecological service function,this paper calculated the ecological service value of forest,grassland,and farmland.It found that the ecological value of forest and grassland per unit area was greater than the ecological value of agricultural industry.This indicates that the opportunity cost of farmland for ecological construction was less than that of agricultural industry.Based on the theoretical and quantitative analysis,it came up with recommendations for establishing a comprehensive system for prioritizing ecological construction with consideration of agricultural industry development and establishing and improving the incentive mechanism of ecological construction.

Ecological construction-An alternative developing way for developing countries

Based on case studies and experience of Chinese urban and rural development, the concept of ecological construction may be the feasible way for developing countries.

LANDSCAPE ECOLOGICAL CONSTRUCTION IN RURAL CHINA:THEORY AND APPLICATION

In landscape with overpopulation, intensive management for economic production, and where even small natural-vegetation patches are scarce, ecological conservation generally must be developed in the course of economic development. Thus “landscape ecological construction” has evolved in China. This approach adds spatial elements and alters landscape pattern to strengthen inter-ecosystem linkages, improve functioning of damaged ecosystems, and increase productivity and stability of the whole landscape. Five examples of managed landscapes in China are presented: dike-pond systems in a river delta; multi-pond system in a rice paddy landscape; field-grass-wood grid system on unstable sand dunes; shelterbelt network in a crop field area; and field-grass-wood mosaic system on highly erodible hilly farmland. These indicate that ecological conditions can be improved along with increased economic production. Altering landscape structure and ecological flows by introducing small landscape elements in distinct spatial patterns is considered a key to the results. This reshaping of the land has focused on changing patch size, regularity of arrangement, biological and hydrological corridors, and networks, the matrix and grain size. It suggests that such changes can increase negative feedbacks and increase stability. Finally, planning and design principles are pinpointed for the landscape ecological construction process.

On ecological inheritance construction of intangible cultural heritage in era of intellectual media

It is known that intangible cultural heritage is an important resource of the cultural soft power in a country, and it is also an organic component and representation of national history, spirit and cohesion.Therefore, a good inheritance of intangible cultural heritage is of great significance for carrying forward the ethical basis of human culture as well as maintaining its value core. Nowadays, the rapid intelligentization of media has ushered in the era of intellectual media, with characteristics of “massive media, man-machine integration and self-evolution”. In the era of intellectual media, traces of intelligent technologies can be seen everywhere, and the ecology of the inheritance of intangible cultural heritage has been reconstructed. Under this circumstance, the author firstly makes clarification of the advancement of the era, which has given a new logic of intangible cultural heritage inheritance, and various intelligent powers should be developed including intelligent acquisition, processing and judgement ability of content value. Then, the technology empowerment is analyzed, which has made reconstruction of intangible cultural heritage inheritance: while being digitalized,the inheritance of intangible cultural heritage has become systematized in way of “Points, Lines and Planes” at the same time. Therefore, the communication ecology of intangible cultural heritage could be established as a new approach of inheritance via all sorts of intelligent technologies, so as to promote Chinese cultural soft power and enhance our national image in the long run.

SUSTAINABLE RURAL LIVELIHOOD AND ECOLOGICAL SHELTER CONSTRUCTION IN UPPER REACHES OF CHANGJIANG RIVER——Case Study of Zhaotong of Yunnan Province

Sustainable livelihood theory provides a comprehensive framework for understanding the interactions between livelihoods of peasant households and regional environment change in low-income areas. Based on field survey and 946 questionnaires from peasant household conducted in the case study area of Zhaotong, Yunnan Province, the paper has analyzed the basic characteristics of the rural livelihoods, including the asset base status, the income-generating activities, the energy consumption pattern, and the fertility behavior, in the upper reaches of the Changjiang (Yangtze) River. The micro-level findings show the conflicts among extensive agricultural development models, rural energy consumption structures heavily relying on biomass and the environment protection. The conversion of cropland to forest and grass program(CCFGP) has exerted an important influence on the livelihoods of the peasant households, but its design has given little considerations to their long-term livelihood sources, which will affect its sustainability to a great extent. From the perspective of sustainable livelihoods framework, the objectives that must be addressed in the ecological shelter construction in the upper reaches of the Changjiang River should include, first, facilitating access of peasant households to credit, technology and public services, second, encouraging the peasant households to adopt agricultural technology with environmental benefits and strengthen resources-conserving investments, and third, paying close attention to the rural energy problems and the long-term livelihood sources of the households with CCFGP. Given the weak asset base and difficulties of livelihood strategies shift, ecological shelter construction in the upper reaches of the Changjiang River will take a long time.

How does the construction of China’s ecological civilization affect the health burden of urban and rural residents?

Accelerating the construction of ecological civilization and promoting the management of health environment problems is one of the core elements of the implementation of the“Beautiful China”and“Healthy China”strategies with Chinese characteristics in the new era.Based on the scientific connotation of ecological civilization,this paper systematically assesses the level of interprovincial ecological civilization construction in China using the combined CRITIC empowerment method and explores the impact of ecological civilization construction on the health burden of urban and rural residents using interprovincial panel data from 2003 to 2018 with the help of panel feasible generalized least squares,simultaneous equation estimation,and the extended regression model.It is found that there is a significant inverted U-shaped relationship between provincial ecological civilization construction and urban and rural residents’economic health burden,as well as a significant U-shaped relationship between ecological civilization construction and urban and rural residents’disease burden.Fiscal decentralization,urbanization,and industrialization are the three important indirect mechanisms through which ecological civilization affects the health burden of urban and rural residents,and fiscal decentralization plays a typical role in crowding out the health effect of ecological civilization.In the eastern and central regions,ecological civilization construction has effectively reduced the health burden of urban and rural residents,but it is more significant for improving the economic health burden of rural residents.While the“catching-up trend”of the progress of ecological civilization construction in the western region is obvious,ecological civilization plays an important role in alleviating the economic health burden of urban residents.After the robustness test,the conclusion still holds.This study provides an important empirical basis for local governments to improve the accuracy of their policies in promoting the“Beautiful China”and“Healthy China”strategies.

Spatial Pattern and Influencing Factors of Regional Ecological Civilisation Construction in China

Ecological civilisation construction is a strategy for regional sustainable development based on a regional system of human-land relations. The comprehensive measurement and regional differentiation in construction levels are the key issues of ecological civilisation construction. This study aims to build 35 index systems that coalesce on four aspects: ecological economic adjustment and operation, ecological and social development and progress, ecological resources and environmental security, and ecological institutional and cultural awareness. We measured and evaluated the level of ecological civilisation construction of 329 cities(prefecture-level cities, autonomous prefectures and leagues) in 2018 using a comprehensive evaluation system and a spatial autocorrelation method to assess spatial differences in the level of ecological civilisation construction across China. This approach takes ‘the humanities-economic geography’ comprehensive perspective and uses a GWR(geographically weighted regression) model to analyse 10 influencing factors. Results show that: 1) the level of ecological construction can be divided into five types: higher, high, medium, low, and lower levels, according to the evaluation score. The five types are spindle-shaped in quantity and there is a significant imbalance in their spatial distribution, mainly trending from the southeast coast to the northwest. The land is decreasing, and the southern region is higher in level than the northern region. 2) The results of the spatial autocorrelation method show obvious spatial differences in ecological civilisation construction across China and that the level of ecological civilisation construction is positively autocorrelated. From east to west, the hot zone gradually transitions to a cold zone. A high-high type is mainly distributed in eastern coastal cities of China, and the number of high-low and low-high types are small. The low-low type is mainly distributed in the northwestern and northeastern regions. 3) The effect of influencing factors is heterogeneous in their spatial distribution, and the abundance of ecological resources is the most influential factor. According to the main influencing factors, each region should adhere to the principle of differentiation according to local conditions when choosing its ecological civilisation construction path and establishing an assessment mechanism. This study provides a scientific basis for enriching the regional level measurement of ecological civilisation construction, clarifying the current level of ecological civilisation construction in China, and implementing the regional differentiation path of ecological civilisation construction.

A climatic environmental performance assessment method for ecological city construction:Application to Beijing Yanqi Lake

In contrast to the input perspective for evaluating planning metrics, this research takes the climatic environmental output effects as the starting point for assessing ecological city construction. Based on approaches such as observation data analysis, meteorological model simulation, and remote sensing, a set of climatic environmental performance assessment methods is developed and established. These methods mainly focus on surface ventilation assessment and urban thermal environment assessment. With the Yanqi Lake ecological development demonstration area located in Huairou district, Beijing as an example, the assessment of the local climatic environment before and after the construction are conducted, and relevant policy suggestions for urban planning and construction are presented. The results show that after development, the ventilation capacity will decrease overall and the ventilation potential index will decrease from 0.53 to 0.44. While this is not a large reduction, and is still at a favorable level, the ventilation potential in some local areas will markedly decrease. Furthermore, the thermal environment will become poorer to some extent; the urban heat island(UHI) area and intensity will increase compared with the current situation;continuous heat islands may occur in local areas; the UHI potential index of the core area will rise from 0.0878 to 0.1217(still a favorable level).Therefore, urban surfaces should be carefully developed and arranged during planning. It is suggested that the negative impacts of large areas of urban construction on the local climatic environment in the Yanqi Lake could be mitigated by 1) strengthening the airflow by introducing fresh,cold, northwesterly air via constructed ventilation corridors, 2) increasing the number of ecological cold sources, particularly for water bodies and green belts to prevent the UHI in the southern region of Yanqi Lake from becoming linked with each other, and 3) considering a pre-program before sub-domain and building planning to obtain optimum building locations. Different construction standards should be developed for different ventilation potential and UHI intensity levels. For strong heat island areas, land areas should be reserved to serve as cold sources.

An analysis on ecological civilization construction in Gansu based on a quantified SWOT framework

Ecological civilization （EC） construction has become one of the key elements of China＇s reform and development process, since it was put forward at the 17th National People＇s Congress （NPC） in 2007 and improved at the 18th NPC in 2012, and stressed at the third plenary session of the 18th NPC. The provincial areas are the most important pilot units of EC strategy. Therefore, research on EC at the provincial level can meet the practical demand for EC in China. Based on the existing provincial circumstances in Gansu and its significant position as an ecological barrier in northwestern China, and aiming at the core issue of why and how to build EC in Gansu, this paper employs SWOT （strengths, weaknesses, opportunities, threats） analysis, the Delphi method, and a combined quantitative analysis and coordinate method, and then calculates the relevant strategic orientation angle （0 = 1.4605） and strength coefficient （p = 0.53）. The results show that Gansu should take an opportunities-dominated strategy, and choose opportunity-strength measures, so the province can increase its in- ternal strengths and decrease its weaknesses with external promote an EC construction strategy. opportunities. Specific measures are recommended to actively

Focus of the Construction of the Ecological Civilization in Socialism with Chinese Characteristics in the New Era

Marx and Engels related and analyzed the relationship between humans and nature as early as more than 100 years ago. and they revealed the interdependent and indivisible relationship between humans and nature in the development of the human society and history from the perspectives of the dialectical materialism and the historical materialism. The Communist Party of China has always attached great importance to the ecological problems. The ＂17th CPC National Congress＂ wrote for the first time the ＂ecological civilization＂ into the political report. The ＂18th CPC National Congress＂ placed the construction of the ecological civilization in a prominent position, emphasizing that the ecological construction should be integrated into all aspects and the whole process of the economic construction, the political construction, the cultural construction and the social construction. The report of ＂19th CPC National Congress＂ promoted the construction of the ecological civilization to a new strategic level, and made an Omni-directional discussion from a new height, the new goals. the new values, the new roles and the new initiatives and other aspects.
