Aanlysis on Dynamic Change of Eco-environmental Quality in Kaiiuan Mining Subsidence area

摘要

In this paper, Remote Sensing images were selected as the data resource. An eco-environmental quality evaluation model which contained forest and grass cover index, wetland cover index, landscape index, biological abundance index, and poor degree of ecological was established, and was applied to the analysis on dynamic change of eco-environmental quality in kaiiuan mining subsidence area. The results showed that the eco-environment quality of Kaiiuan mining subsidence dropped first, latter rise unceasingly and the eco-environmental quality in 2009 was best. It is consistent with the actual situation.
