摘要：以四川省水土流失重点防治区遂宁市的3个小流域为研究对象,采用Costanza生态系统服务价值计算方法,参照中国陆地生态系统单位面积生态系统服务价值当量表,结合研究区粮食平均产量和收购价格,分析了紫色土区水土流失治理工程对生态系统服务价值的影响。结果表明:1999—2003年间,各流域林地和草地面积呈增加趋势,耕地和未利用地呈减少趋势。各流域单项生态服务功能在气候调节、水源涵养、土壤形成与保护等方面有所增强,在食物生产方面减少8.90万～62.30万元;生态服务总价值和人均生态系统服务价值则均有不同程度增长。各流域生态经济协调度在0.0565～0.8413之间,表明生态系统服务价值的增长速度低于经济增长速度,应继续加强水土保持工程区的生态环境建设。
Three small watersheds with severe soil erosion and water loss in Suining City, Sichuan of southwestern China were taken as research objects. Referencing Constantan＇s calculation method and table ecosystem service value per unit area of Chinese terrestrial ecosystem, combining with the local average grain yield and grain purchasing price, this paper analyzes the effects of soil and water conservation project on ecosystem service values of small watersheds in purple soil region. The results indicated that the areas of forest land and pasture land increased, cultivated land and unused land declined from 1999 to 2003. The single ecosystem service values of three watersheds increased in atmosphere regulation, water conservation, and soil formation and conservation function, while food production decreased by 8.90 × 10^4 to 62.30 × 10^4 RMB. The total ecosystem service values and per capita ecosystem service values increased in varying degrees. The eco-economic harmony degree was between 0. 056 5 and 0. 841 3, showing that the growth rate of ecosystem service value was lower than that of economic in each watershed. More attention should be paid to ecological construction in soil and water conservation project region.
