摘　　要：小水电代燃料生态保护工程是以生态效益为主的一项公益性工程,水土保持效益突出。本文将小水电代燃料生态保护工程的水土保持效益分为两类:一是保护森林,涵养水源的效益;二是减少土壤侵蚀的效益。并分别探讨了涵养水源、减少土壤侵蚀、减少土壤养分流失及减少水库泥沙淤积的效益量化计算方法,以山西省陵川县马圪当小水电代燃料试点工程为例进行了水土保持效益的实例计算。The small hydropower station for fuel project is a commonweal project, give prominence to the ecology benefit. This paper classifies the soil and water conservation benefit of the project into water conservation benefit by forest and soil erosion reducing benefit. And study the quantified methodology of self, restraint the source, the soil erosion reducing, the soil nutrient prediction and reservoir mud alluvial prediction, and applies the model count the water conservation benefit in Lingchuan county Magedang experimental unit in Shanxi province.
