Abstract :
Basing on multi-source remote sensing data, statistical data, supporting of GIS technology, this study carried out the research on comprehensive evaluation of the ecological environment quality of resource-based city - Panzhihua City from five aspects which is biological abundance, vegetation coverage, water density, land degradation and pollution load. The results show that the quality of the overall situation of the ecological environment in Panzhihua City was divided into 5 categories from good to bad, and the area accounting for the city area respectively is 6.58%, 29.44%, 37.04%, 22.65% and 4.29%. The ecological environment situation Along the Jinsha River and Anning River is significantly worse than other regions, and more near from the river, the poorer the quality of the ecological environment. In order to improve the ecological environment of the study area, ecological reconstruction of mining zone region should be strengthened, clean production process should be through every aspect of mineral development, Returning farmland to forest projects should be continue to actively and steadily push forward, and soil erosion should be control maximally.
