摘　　要：文章从土壤保护和涵养水源功能入手,通过实验得到四川地区不同地貌、不同建成年限、不同工程区域的土壤比重、容重及质量含水率值,计算得到土壤饱和持水量,确定土壤保护和涵养水源功能在项目建成5年后基本恢复,且污水池及管道建设对该功能有一定增益作用,最后通过影子工程法得到土壤保护和涵养水源功能的补偿价值量。This paper starts with the function of soil conserving and water resource,and focuses on the specific gravity,bulk density and mass water content of soil in diverse landforms,different built-up years and various project areas in Sichuan.Accordingly,the saturated water holding capacity of soil can be calculated through experiment.In addition,it can be predicted that the function of soil conserving water resource will be basically restored after 5 years of construction,and the construction of sewage pools and pipelines will have a certain gain on this function.Finally,the compensation value of soil conserving water resource function can be obtained by shadow engineering method.
