Abstract


Luoyang Xin'an Power Group Wanji Aluminum Co., Ltd. is Mine Environmental Impact Assessment study instance , multi-spectral remote sensing digital image -based remote sensing surveys and environmental vulnerability discriminant analysis as a means to the ecological environment in the construction project quantitative evaluation of eco - environmental impact a useful attempt . In this study, using SPOT-5 satellite ( panchromatic / multispectral ) high-resolution digital images , digital mosaic , fusion generated in the study area orthophoto map as the basis of the remote sensing survey evaluation . Orthophoto map in the PCI data processing platform thematic information extraction, and through the MAPGIS information processing platform in turn generated by the spatial database management Mine area and control area \type \Landscape ecological system according to relevant national standards , in the process of conducting spatial analysis using analytic hierarchy process for quantitative assessment of the ecological environment around the mine development trends , regional environmental vulnerability rating calculations obtained due to mine development on the ecological environment . conclusion. Namely : ( 1 ) is the village of mine ( pending development zone ) and adjacent Xin'an coalfield developed image texture control analysis showed that the mine development to regional geomorphological and ecological landscape change is the most profound is the shrinkage of the areas covered by loess , mountain cinnamon soil area is reduced , skeletal soil barren area of ??rapid expansion , and dominant strength over soil erosion area . Coalfield also face problems of environmental geology , ground subsidence , ground fissures , the gangue emissions , waste water pollution and other issues . ( 2 ) According to the fragile ecological environment evaluation results , is the village of mine development to the fragile ecological environment before value G score was 0.512 , close to moderate vulnerability zone ( Table 7-3 ) . Mine development G score will rise to 0.630 , close to the fragile area of strong , very obvious trend of ecological deterioration ( Table 7-2 ) .
