摘　　要：水土保持作为生态环境建设的重要内容,是一项实践性较强的农林水事活动。为了评价水土保持的实施效果、明确水土保持的目的与意义、对不同的水土保持方案进行比较与优选,有必要进行水土保持效益评价研究。其中生态效益在保持和改良土壤、涵养水源、固碳供氧和维持景观等方面体现重要的价值。本文通过生态效益指标体系、生态系统服务功能的水土保持效益评价和水土保持生态建设的效益评价指标体系简要说明水土保持的生态效益。Soil and water conservation as an important part of the ecological environment construction, is a strong practice of agriculture, forestry and water activities. In order to evaluate the effect of soil and water conservation, to clear the purpose and significance of soil and water conservation, to compare and optimize the different soil and water conservation programs, it is necessary to carry out soil and water conservation benefit evaluation research, in which ecological benefits reflect the important value in maintaining and improving the soil, water conservation, carbon seques- tration and maintaining the landscape and so on. This paper briefly describes the ecological benefits of soil and water conservation through the evaluation index system of ecological benefit index system, the benefit evaluation index system of soil and water conservation ecological cons- truction and the evaluation of soil and water conservation benefit of ecosystem service theory.
