摘　　要：为了客观定量评价天水藉河示范区一期和二期的水土保持效益,结合国家标准和示范区实际情况,建立了一套适合该区的水土保持效益评价指标体系,并用该指标对该区调水保土效益、经济效益、社会效益和生态效益进行了评价。结果表明:选取的评价指标体系和采用的评价方法能较为全面地反映水土保持的综合效益,具有一定的区域适宜性;示范区通过两期水土保持生态工程建设,取得了显著的调水保土、生态、经济和社会效益。本研究对水土保持效益评价体系的完善以及示范区可持续发展具有积极的作用。In order to evaluate the benefit of the soil and water conservation objectively and quantificationally during the first and second period of Jihe watershed,this paper built a set of index system of benefit evaluation of soil and water conservation,which intergrated national standard and practical matter of Jihe watershed,then evaluated the benefit of regulating soil and water conservation,economic benefit,social benefit and ecological benefit.The result demonstrated that evaluation using the established evaluating system and the applied method can well relfect the comprehensive benefit of soil and water conservation,and show certain regional applicability.Soil and water conservation of the demonstration zone yielded remarkable regulation of soil and water conservation,ecological,economical and social benefits by two stage ecological engineering construction.The results of this research have positive effect on perfecting the index system of soil and water conservation and promoting sustainable development of demonstration zone.
