| Abstract: | Based on the grey associative theory,an eco-environmental assessment model of basins is established. As a case, the eco-environmental evaluation index system of Chaohu Lake Basin is formulated, and classified standards of evaluation indices are put forward. The established model is utilized to evaluate the eco-environmental quality of Chaohu Lake Basin. Study result shows that Grey Associative Model(GAM) can not only reflect the eco-environmental quality state of a basin objectively and accurately,but also can be used to contrast the environmental quality of different districts or periods. Therefore, GAM is an ideal method for eco-environmental evaluation of a basin. |
