- Abstract:
-
It is a real problem that the ecological environment had been everely damaged by the 5·12 Wenchuan earthquake for the Longmen region. The comprehensive evaluation of the ecological environment has been completed through using of the analytic hierarchy process and GIS technology by constructing the target layer, constrained layer, feature layer and the establishment of a comprehensive evaluation model of the ecological environment in Pujian County. The results showed that percentage of ecological environment more than third grade in Pujian County reached to 87.6%, and the overall ecological environment in this county was in good condition. Meanwhile, ecological protection countermeasures were proposed in this paper.
