山区小流域水土流失综合治理经济评价与效益分析——以天台县祥和溪等5条小流域为例

摘要

从天台祥和溪等5条小流域水土流失现状分析和水土流失综合治理措施出发,通过对坡改梯、水保林、经济林和小型水土保持工程的投入和效益分析,论证了水土流失综合治理的基础效益、生态效益和经济效益;同时通过对项目进行国民经济评价,经济内部收益率（EIRR）、经济净现值（ENPV）和效益费用比（EPCR）3项指标均达到要求。%Based on the current soil and water loss in five small basins,e.g.Xianghe Brook in Tiantai County,and comprehensive regulation measures,this paper argues the basic,ecological and economic benefits by analyzing the investment and benefits of slope-to-terra
