Abstract
Considering the various influencing factors of eco-environmental quality in Lake Dianchi Basin, the evaluation indexes of eco-environmental quality such as biological abundance index, vegetation coverage index, water network density index, land degradation index and environmental quality index are determined. The weight values of factor indexes are given by using the quantitative and qualitative model of analytic hierarchy process (AHP) and the eco-environmental quality of Lake Dianchi Basin was evaluated by using the quantitative and qualitative model of ecological index (EI). The evaluation results show that the grade of eco-environmental quality is weaker and the environment for human survival is harsh. The evaluation result is in good agreement with the results of previous studies. The evaluation system established in the paper can be regarded as a reference model for eco-environmental quality evaluation.
