摘要
以2000、2005和2010年陕北黄土高原地区土地利用数据为基础，在收集已有生态系统服务功能价值研究成果的基础上，对区域内2000—2010年生态系统服务功能价值变化进行分析。结果表明：受退耕还林还草工程实施影响，陕北黄土高原地区耕地大面积减少，草地大面积增加；区域内总体生态系统服务功能价值增加，共增加9500万元，林地贡献较大；生态系统服务功能中，废物处理、食物生产、水分供应和气体调节功能价值最大；废物处理、侵蚀控制和娱乐功能价值增加最大，而土壤形成、水分供应和气候调节功能价值减少最大：娱乐、水分控制和侵蚀控制功能价值增加幅度最大，而土壤形成和气候调节功能价值减少幅度最大。
Land use data in the year of 2000, 2005 and 2010 was used to analyze ecosystem services value change from 2000 to 2010 on the ba- sis of collected research results of ecosystem services value. Result showed：Farmland was decrease largely while grassland was increase largely in Loess Plateau area of northern Shaanxi Province influenced by GGP. The overall ecosystem services value was increase with 0.95 ~ l0s yuan, and woodland was contribute greatly. In the function of ecosystem services, the value of waste treatment, food production, water supply and gas regu- lation function was the biggest. The value of waste treatment, erosion control and entertainment function was increase largely, while the value of soil formation, water supply and climate regulation function was decrease largely. The value of entertainment, water control and erosion control function was with the largest increased percentage, while the value of soil formation and climate regulation function was with the largest decreased percentage.
