China's Coal Resources "Well" Word Distribution Characteristics Of Environment And The Jin Shaan Meng Ning Area Ecological Binding Study

Ecological binding,also known as ecological constraints,is a period of a certain region in a particular ecosystem can support of the total population,economic strength and social factors and degree.Now with the scale development of coal mining area,in addition to resource,environmental problems,under the principle of "people-oriented" society,people's all sorts of consciousness also increased,natural,mining development in various social problems become one of the main factors of restricting the development.In this paper,guided by the sustainable development thought,accordance with the requirements of the environmental impact assessment act,"well" word for China's coal distribution pattern,summarizes the ecological environment features of different coal resources development area,combining with the characteristics of development of the environmental impact of coal mining area,has been clear about the concept and connotation of mining area ecological binding,focus on building the JinShaanMengNing ecologic binding quantitative model and index system.On the basis of the existing data,the JinShaanMengNing mining area ecological binding condition is evaluated,and the ability of mining area sustainable development put forward the suggestion,for mining area will provide a scientific basis for reasonable development goals.The main conclusions of this paper are as follows:(1)The research concluded that China's coal resources "well" word area corresponding to the nine coal development zone characteristics of ecology and environment,the overall look at western has a relatively rich coal resources,ecological environment fragile,backward economic development and the relative shortage of coal resources in the east,has good ecological environment,the characteristics of the rapid economic development.;(2)According to the ecological environment of coal area characteristics and characteristics of coal mining impact on the environment and establish a suitable for mining area to develop a set of assessment of ecological binding contains "resources-environment-society" rule of three,21 points index recursive step by step,level 4 overlay,relatively perfect comprehensive evaluation index system;(3)In view of the jinshaan MengNing coal area ecological environment current situation and existing problems,combining with the characteristics of the ecological environment,the application of mining development ecological binding evaluation index system of comprehensive evaluation method is adopted to improve the jinshaan MengNing coal area to study the ecological binding,recognition of the mining area development key ecological binding as follows: resource constraints restrict > > environment social constraints,and aims at the main ecological factors of the regional water resources,land resources,water environment and resources "preliminary suggestion to realize the sustainable development of ecological restoration.(4)Application of the mining area ecological binding evaluation index system,put forward "well" glyph distribution of coal resources in our country the development of sequence is: the jinshaan MengNing coal area,northern xinjiang coal area to the nanjiang coal area,yunnan-guizhou each coal area to the northeast area of coal,coal south China area to MengDong coal district,huang-huai-hai coal area.
