A Study Of The Assessment Of Ecological Environment Quality In Shanxi Province Base On The Ecological Footprint Model

Shanxi Province, which is located in the central position of our country, has abundant the mineral resources, and it is the important heavy chemical base of energy of our country. Since the reform and open policy , the large-scale energy series chemical industry construction, has made the significant contributions for the local economic development and the nation national economy construction, however, with exploitation of large-scale, high-strength, big-area's to mineral resource and rapid development of each kind of height consumes energy industry, the ecological environment of entire province has worsened rapidly, which has caused a series of ecological environment problems, such as the ecological environment to be frail, the soil erosion is serious, the water resources is short, person field contradiction is strained, etc.. Those have serious restricted economy and the social development in Shanxi. Aggravation of part area ecological environment threaten this province economy sustainable development and the people's health, and endanger peripheral province, therefore, it contains important meaning to carry on the appraisal to ecological environment quality of Shanxi Province.Under the guidance of the theory of systemization, the author states the theory of Ecological Footprint method. Based on the model of Ecological Footprint, the paper has structured the calculation model of the ecological footprint quantity in Shanxi, has carried on calculate to the ecological footprint amount of the whole province from 1995 to 2005, and comparative analysis the sustainable development ability of the ecological environment in Shanxi based on ecological footprint amount of different year correctly. It has cleared about the sustainable development state of ecological environment which current Shanxi. As well as, it offers policy guidance and scientific basis for social economy sustainable development of Shanxi.Through analysis of ecological footprint quantity, the paper draws the following conclusions: (1)The result shows during 11 years except very few years the ecological footprint and the ecological deficit are increasing. Such growth in ecological footprint and deficit means that there is a greater pressure on ecosystem.( 2 ) In six lands, the footprint of fossil energy land accounts for average78.52%. Secondly,the footprint of cultivate land footprint accounts for average12.62%.(3)The paper analyzes the ecological footprint of 11 districts in 2005 respectively, which result shows the regional difference of ecological environment deterioration,thus , each district should adopt appropriate measures to improve local conditions.(4)In Shanxi, the main ecological environment question includes the following several spots at present: firstly, environmental pollution was serious, which intensifies the ecology to be unbalanced; secondly, the mine exploitation destruction is serious; thirdly, the soil erosion is serious, the land quality drops; next, the water resources is short, the waste and the pollution are serious; once more, the land desertification is serious, the sand blowing, the sand storm are frequent; finally, the vegetation is sparse, the forest destruction is serious. The primary cause due to long-term reliance on economic status of energy and heavy chemical industry as the main body of a single model of industrial with coal and related industries, results of ecological erode long-term accumulation.
