【摘要】 选取煤矿型城市淮南市区为研究区域,以2017年12月淮南市Landsat-TM影像、淮南市采煤塌陷地分布矢量图和全国第二次土地调查的土地利用数据为数据源,在GIS技术支撑下,从生态敏感性和生物多样性服务价值两个方面评价采煤塌陷区的生态恢复优先级,利用GIS中的自然断点法将生态恢复优先级分为非常低、低、中等、较高和高5个级别。结果表明:淮南市区生态恢复优先级高和较高的塌陷区面积所占比例为27.34%,主要分布于潘集区采煤塌陷区的中南部、八公山区采煤塌陷区的大部分区域、谢家集区采煤塌陷区的西北部以及大通区采煤塌陷区的大部分区域,建议将这些区域予以优先恢复。更多还原

【Abstract】 This paper takes Huainan City as the research area,with the Landsat-TM image of Huainan City in December 2017,the vector distribution map of coal mining subsidence in Huainan City,the Huainan municipal area vector map and land use data for the second national land survey as data sources,under the support of GIS technology,comprehensively evaluates ecological restoration priorities in coal mining subsidence area from two aspects:the ecological restoration priority from low to high are very low,low,medium,high and very high by using the natural breakpoint method in GIS. The results show that the recovery in high priority and higher subsidence area accounted for 27.34%,mainly distributed in central and southern area in coal mining subsidence of Panji District,the northwestern part of the coal mining subsidence area of Xiejiaji area and most of the coal mining subsidence area in Datong and Bagongshan District,it is recommended that these areas be given priority recovery.更多还原
