神东矿区主要矿井采区和非采区植被差异分析

Analysis of Vegetation Difference between Mining District and Nonmining District of Main Mine in Shendong Mining Area

基于Landsat/HJ-CCD数据计算了神东矿区归一化植被指数(NDVI),并从矿井尺度分析了神东矿区9个主要矿井采区和非采区植被NDVI差异性。结果表明:采区地表植被相对于非采区植被未出现大面积的衰退和破坏;地下采煤活动对风积沙覆盖的采区植被带来的负面影响比较大,对覆沙硬梁区的负面影响则比较小。

Based on the Landsat data/HJ-CCD, NDVI of the Shendong mining area is calculated, and NDVI anomaly analysis of the nine main mining areas and non-mining areas in the Shendong mining area is analyzed from the mine scale. The results show that there was no large area of decline and destruction in the vegetation of the mining area compared with the non-mining area. The negative impact of the underground coal mining activity on the vegetation occupied by the aeolian sand was relatively large, and the negative effect on the sand cover area was small.
