Ecological vulnerability of coal mining area: A case study of Shengli Coalfield in Xilinguole of Inner Mongolia, China
摘要
Abstract
In this paper,an ecological vulnerability evaluation index system for the Shengli Coalfield in Xilinguole of Inner Mongolia was established,which included 16 factors in ecological sensitivity,natural and social pressure,and ecological recovery capacity,respectively.Based on the expert scoring method and analytic hierarchy process (AHP),an ecological vulnerability model was built for the calculation of the regional ecological vulnerability by means of RS and GIS spatial analysis.An analysis of the relationships between land use and ecological vulnerability was also made,and the results were tested by spatial auto-correlation analysis.Overall,the ecological vulnerability of the study area was at medium-high level.The exploitation of four opencast areas in the Coalfield caused a significant increase of ecological vulnerability.Moreover,due to the effects of mine drained water and human activities,the 300-2000 m around the opencast areas was turning into higher ecologically fragile area.With further exploitation,the whole Coalfield was evolved into moderate and heavy ecological vulnerability area,and the coal resources mining was a key factor in this process.The cluster analysis showed that the spatial distribution of the ecological vulnerability in the study area had reasonable clustering characteristics.To decrease the population density,control the grazing capacity of grassland,and regulate the ratios of construction land and cultivated land could be the optimal ways for resolving the natural and social pressure,and to increase the investment and improve the vegetation recovery coefficient could be the fundamental measures for decreasing the ecological vulnerability of the study area.关键词
