Regional Distribution and Sustainable Development Strategy of Mineral Resources in China

This paper summarizes the distribution and production layout of the major mineral resources in China,including coal,iron ore,copper and bauxite,from a national perspective.It also identifies the incompatibility between the mineral resources distribution and regional economic development.Significant issues with China's mineral resource industry cause challenges for the sustainable development of both the mining industry and the national socio-economy.The sustainability of regional mineral resources and the environmental pollution by mining in the western China were also analyzed.Results show that the distribution of China's mineral resources is misaligned with its regional layout of economic development.China's mineral resources have been over-exploited,and the mineral resources production in the eastern China is unsustainable.The continuously expanding production of mineral resources in the western China has heavily endangered the ecological environment.We propose strategies to boost the sustainable development of mineral resources,including measures to accelerate economic development and enhance the sustainability of domestic mineral resources.We also offer suggestions for scientifically planning the mineral resource prospecting and exploitation and regional economic layout,as well as for proactively undertaking industry transfer in the eastern China and raising the environmental benchmark requirements for the mineral industry in the central and western China.

Coordination of economic development and ecological environment in resource exhausted cities

This paper establishes the evaluation index system of ecological environment and economic development in resource exhausted cities, and calculates the level of economic development and ecological environment during the year 2005-2012 by using the entropy method. Furthermore, this study analyzes the coordination degree and coordinated development degree by using the coordination model. The results show that the coordination relationship of economic development and ecological environment continues to improve from 2005 to 2012 in most of these resource exhausted cities. By 2012, other resource depletion cities are in all kinds of hierarchical coordination except Yichun and Hegang. From the standpoint of coordination development degree, although most of these resource exhausted cities have been increased continuously but the level is also lower except in Tongling and Xinyu. Finally, this paper puts forward the corresponding countermeasures and suggestions according to the results of the analysis.

The Preliminary Research and Analysis of Ecological Environment Construction in the Small River Basin——A Case Study in Taojia Small River, Yunnan

Through nearly seven months of investigation and research, detailed information and data on vegetation resources, land resources and other ecological resources in the Taojia small river basin were obtained, and the data were analyzed and processed. The results show that due to the destruction of forest vegetation, the steep slope reclamation and water channel leakage in the Taojia small river basin, well fields and forest land at multiple sites in the basin have been buried by mud and rock, and abundant forest vegetation distributed in the middle and upper reaches has reduced to the situation of a forest coverage rate of only 15.5%. As a result, a vicious circle of "ecological destruction, soil erosion, farmland reduction, poverty, steep slope cultivation, ecological destruction" has been formed. Based on the analysis of the basic ecological background of the basin, six ecological restoration proposals such as planting soil and water conservation forests and fruit trees and blockading protection were proposed, in order to provide support for restoring the ecological environment of the basin and achieving sustainable development of the ecological environment within the basin.

Relationship between the development of energy and mineral resources and ecological conservation redline

From a philosophical point of view,this study discusses the dialectical relationship between the development of energy and mineral resources and the ecological conservation redline.We propose that the ecological conservation redline and the development of energy and mineral resources should be guided by ecological civilization construction,that is,the energy and mineral resources should be rationally developed under the condition that the ecological environment is protected.This study analyzes the influence of the development of energy and mineral resources on the ecological environment.The handling of mining rights within the ecological conservation redline based on the law and the reduction of the influence of the development of energy mineral resources on the ecological environment by science and technology are presented.The environmental assessment system and technical standards for energy and mineral development are suggested to implement policies and measures for the disposal of mining rights within the redline and facilitate technological innovations of ecological conservation for energy and mineral development.Hence,a coordinated development between the ecological conservation redline and the development of energy and mineral resources can be promoted.

Ecological Environment Conservation and Restoration and Sustainable Development of Minqin Oasis

Minqin oasis in the lower reaches of the Shiyang River is a main natural barrier for the Wuwei Basin. Due to the combined influence of human activities and natural factors in the past half a century, water quality in the lower reaches of the Shiyang River decreased and ecological environment deteriorated, which influenced sustainable development of this area and surrounding area seriously. This paper analyzed current situation and reasons of the deteriorated ecological environment in the lower reaches of the Shiyang River, and proposed that water environment regulation was the primary task in the eco-environment control of Minqin area, specifically,(a) By using existing policies, accelerating the construction of water-saving agriculture in the middle reaches of the Shiyang River, water quantity in the lower reaches would be guanranted, water shortage for agricultural production and ecological use in Minqin oasis would be relieved;(b) Unreasonable human activities such as overexploitation of underground water should be controlled strictly;(c) Water conservancy project should be developed vigorously to ensure rate of flow. It was expected that the above schemes would contribute to the benign circulation of ecological environment in Minqin oasis.

Environmental management and sustainable development in forested mountain areas of northeast China

This paper studied the sustainable development through a reasonable management of the social, economic and natural environment in a forested mountain area of northeast China. In order to show the local people how to manage their most important forest resource, we analyzed the life-history process of the key species and the influencing factors that were associated with the forest regeneration and sustainability. Pollination and fertilization were mainly affected by weather conditions. Light intensity under the forest canopy was the key factor that controlled seedlings growth and saplings survival. Periodic seeds setting caused the fluctuations of rodents and other related animals in the food chain. Squirrels played a very important role in the forest regeneration, theses animals were the absolutely indispensable components of the forest ecosystem. How to understand the co-evolutionary relationships among species in the forest ecosystems was very important for the conservation of biodiversity and maintenance of ecosystem itegrity. In conservation of the natural resources, we studied the social and economic environment of the forested mountain area. It is very hard to effectively protect the forest resources and maintain the normal life of the local people under the regime of the “unified administration and enterprise system”. Reforms are needed both in administrative institutions and in enterprise management. In the end, this paper proposed that we should not only protect the trees, the related animals, the ecological habitats, and the whole forest ecosystems, but also consider the human activities and their basic requirements so as to realize a sustainable development in the forested mountain areas.

Land development suitability analysis for transport planning evaluation and optimization in mountainous ecological region

Transportation planning is a critical component for creating an orderly,intensive,and sustainable pattern of land development.By comprehensively considering the potential and suitability of transport construction,a comprehensive method combining resources and environmental carrying capacity(RECC)and land development suitability(LDS)was developed by using techniques of GIS,analytic hierarchy process(AHP)and threedimensional magic cube.Taking Aba prefecture in Sichuan Province of Southwest China as a case study,LDS for transportation was analyzed from three aspects,including overall planning layout,different transport modes,and transportation projects.The results showed that the transport planning scales of most counties in Aba were suitable,and the order of LDS of different transport modes was railway>highway=superhighway>tourism track,which already included 42 new transportation projects.We found that two counties(Maoxian County and Jiuzhaigou County)should improve the ecological protection level of transportation,in which the railway network construction should be encouraged,and some transportation projects with low LDS should be postponed or constructed harmlessly.We suggest the combination of RECC and LDS for transportation could enhance the territorial space optimization and sustainable transport construction.

An Empirical Study on the Relationship between Urbanization and Changes in Resources and Environment

The expansion of urban scale is the inevitable outcome during urbanization,and it has exacerbated the contradiction between urbanization,and resources and environment. Based on the environmental indicator data related to the urbanization of Chongqing Municipality during the period 2000- 2012,this article uses regression analysis and ARIMA forecasting model to study the impact of rapid urbanization on the resources and environment. It is found that urbanization is significantly and positively correlated with the built-up area,the annual electricity consumption,domestic waste water discharge amount,and industrial waste gas emission,but significantly and negatively correlated with the industrial solid waste discharge amount; before 2020,along with the improvement of the level of urbanization in Chongqing,the degree of deterioration of the environment and resources will be further increased; after 2020,urbanization and ecological environment will be in a new round of balance,and the resources and environment will be improved.
