吉林省煤矿区景观生态风险分析

Analysis on the Landscape Ecological Risk of Jilin Coal Mining Area

为评估煤矿开采对生态环境的破坏和损失程度,制定环境保护与治理方案,运用景观生态风险评价法开展矿区的生态风险评价。以吉林省11个主要煤矿区作为研究对象,以2008年中巴资源卫星遥感影像为数据源,运用景观生态风险分析方法,计算各煤矿区的景观格局指数,绘制生态风险空间分布图,将各矿区生态风险综合指数进行对比。结果表明,吉林省矿区的生态风险总体呈现中部高于南部和东部的规律。就各矿区而言,蛟河和杉松岗矿区生态风险指数值明显高于其他矿区,分别为0.360 2和0.321 0。

The main eleven coal mining areas in Jilin Province were selected for this research.With the method of landscape ecological risk analysis,CBERS remote sensing images obtained in 2008 were used as the main data source,to calculate the indices of landscapes pattern of different coal mining areas and draw the distribution map of the ecological risk.Comparative analysis of ERI between coal mining areas,the values of the mining areas in central Jilin Province are higher than those in south and east parts.The ERI of Jiaohe and Shansonggang mining areas with values of 0.360 2 and 0.321 0,respectively,are significantly higher than others.
