摘　　要：为了评价京津风沙源治理工程草地建设项目所涉及到的山西省13个县区,2006年前完成的基本草地、人工种草、草种基地、飞播牧草、围栏封育等草地生态系统的服务价值。依据学者提出的9种生态服务功能,结合生物量因子等校正,对京津风沙源治理工程草地建设项目所涉及到的山西省草地生态系统的服务价值进行评估。京津风沙源治理工程中,建植或恢复的草地植被,能够为13个县区带来0.754~2.493×108元/a的生态系统服务价值,从提供的生态系统服务价值的构成来看,从高到低依次为：废物处理、土壤形成与保护、食物生产、气候调节、生物多样性保护、水源涵养、气体调节、原材料、娱乐文化,各自所占的比例分别为22.9%、22.0%、13.0%、12.8%、11.0%、9.0%、7.8%、1.3%、0.2%。京津风沙源治理工程总计可为山西省产生2.338×109元/a的生态系统服务价值。The ecosystem services values of basic grassland,tamed pasture,forage seed base,aerial seeding grassland and enclosed pasture were evaluated,which were carried out by the Sand-Source-Control Project around Beijing and Tianjin region,in Shanxi provinc involved in 13 counties.The results showed that annual ecosystem services values of established grassland and restored vegetation ranged from 0.754 to 2.493×108 for each counties respectively.In terms of ecosystem service values,the descending order were waste treatment,soil formation and conservation,food production climate regulation,biodiversity maintain,water source conservation,gas regulation,raw material production,recreation and culture.The proportion was 22.9%,22.0%,13.0%,12.8%,11.0%,9.0%,7.8%,1.3% and 0.2% respectivly.The annual ecosystem services values of established grassland and restored vegetation were 2.338×109 Yuan RMB for Shanxi province.
