南岸区水土保持规划的效益预测分析

Benefit Prediction Analyses on Water and Soil Maintenance in the South Bank District

水土保持作为改善农业生产条件,提高人口环境容量的一项措施,是改善生态环境的重要手段。本文对南岸区水土保持规划进行生态效益和静态经济效益预测分析;应用森林作为"大气的总调度室",分析了其环境作用及带来的间接经济价值,同时通过效益费用比R、净效益C、投资回收年限T、内部回收率I和敏感性分析,得出水土保持规划从生态和经济上的可行性。

Water and soil conservation is a measure which can improve agriculture productive conditions and enhance population enviromental capability and an important way of improving ecological environments. This paper does ecologic benefit and economical benefit prediction analyses to water and soil conservation to the South Bank district. We analyze forests' environmental action and indirect economic avalue through forests act as 'integral controlling houses of atmosphere' .What's more, we make right conclusions of water and soil conservation by benefit cost ratio R, net benefit C, payback period of investment T ,internal rate of return I and sensitivity analyses.
