【 摘 要 】

This paper presented a model based on the analytic hierarchy process(AHP) to evaluate the pollution problem of Yunnan Province. The results show that the sample points meet the general requirements (in and below the pollution risk), accounting for 75% of the total. In the serious points exceeding the standard, the points with high pollution risk account for about 95%, and the classification is more complicated. It is necessary to invest in a larger workload in the later stage for detailed classification, and the super high risk point accounts for about 5%.
