摘　　要：实施传统水土保持措施的初衷是为了保护水源区的土地资源,但由于忽视对下游水资源的影响,随着治理的深入,流域内径流量减少幅度增加,影响了对受水区的供水量。为了保证水源区对受水区的供水量,对传统水土保持措施进行改进、采取新型水土保持措施已成为增加受水区输水量、改善水源区生态的现实选择。基于对水源区传统水土保持措施局限性的分析,得出传统水土保持措施并不适宜大中型城市的水源区治理,并初步探讨了水源区新型水土保持措施的主要内容及其具体的措施配置。The original intention of implementing traditional soil and water conservation measures was to protect land resources of the water source region.But,it affected water supply of the water receiving area,due to neglecting influence to water resources of downstream and the increase of runoff reduction of the watershed along with the deepgoing treatment.In order to guarantee water supply of the water receiving area,improving traditional patterns and taking new soil and water conservation measures had become practical selections for increasing water delivery of the water receiving area and improving ecology of the water source region.It concludes that these measures are inappropriate for soil and water conservation in the water source region based on the analysis of limitations of various traditional soil and water conservation patterns.It also discusses the main principles and concrete configuration measures of new soil and water conservation measures.
