By using three periods(1987,1995,2000) Landsat TM datas of Huangshan City,this paper making a close analysis to the change of land use in research area and effect of eco-environment produced by this change in late ten years.The research revealed eco-environment has degradation tendency,that became relative deteriorated violently especially between 1987 and 1995 year.Meanwhile the heterogeneity existed in different districts:the best eco-environment quality was in Qimen and the eco-environment in Tunxi was the worst of all.In the research period except Xiuning's eco-environment has been improved,other districts has degradated all to different extent,and further,the most violent degradation lying in Huangshan.There is a close correlation between eco-environment and mode of land use,especially the area of forest in land use mode has more direct relation with eco-environment quality.The higher rate of forest coverage,thus the better of eco-environment.To the contrary,the rate of forest coverage reduced,the eco-environment quality correspondingly deteriorated.
