摘要
以神北矿区为例,从区域环境承载力的概念出发,结合3S技术,系统分析了神北矿区环境承载力的影响因素。并以此为基础,建立神北矿区环境承载力评价指标体系。运用环境承载力评价量化模型,对神北矿区环境承载力进行了分析和评价。分析结果表明:评价指标中土地沙漠化、矿山开发、水质环境容量环境承载力超载,分别为-17.8%、-2.6%、-9.8%;水资源量环境承载力可载,为30.8%;矿区综合环境承载力仅为14.1%,说明矿区综合环境容量几达承载极限。
On the basis of the study of regional ECC（environmental carrying capacity）,taking Shenbei mining area as an example and combined with ＂3S＂ technology,this paper systematically analyzed the influencing factors of ECC,and constructed the index system of ECC of Shenbei mining area,analyzed,calculated and evaluated the ECC of Shenbei mining area.The results showed that ECC of land desertification and mine exploitation and water resource quality have been overflown with overflow percentum of -17.8%,-2.6% and -9.8%;ECC of water resource quantity is comparatively well,its potential percentum is 30.8%.The integrated ECC of Shenbei mining area is only 14.1%.The results showed that the integrated ECC of Shenbei mining area is approaching the limit of overloading.
