| Abstract: | AHP belonging to operational research is adopted when the effects of the rainwater resources utilization on eco - environment is researched in Taohe watershed in Yangquan, with the combination of qualitative analysis and quantitative analysis , on the foundation of the benefit on soil and water conservation, the evaluation index system including ratio of cropland to slope area, soil erosion modulus, cropland index, vegetable coverage, management degree is established. The solving weights of each index to the ecological benefit are calculated, the mathematic model of ecological benefit evolution is established ,. and the changes of ecological benefits in different periods are analyzed and evaluated. |
