中文摘要	基于2000/2005/2010年三期土地利用现状遥感监测数据,利用GIS空间分析技术,分析长江流域土地利用变化方式、过程、区域特征和生态系统服务功能变化。研究表明:2000~2010年长江流域城乡建设用地、林地和水域面积增长显著,而耕地、草地面积持续减少:耕地减少和城乡建设用地增加相关,草地减少和林地增加相关,水域增加与三峡蓄水及退田还湖相关:四川盆地、中游城市群和长三角城市群等人类活动热点区域的土地利用程度显著提高;受土地利用变化影响,2000-2010年长江流域生态系统服务总价值逐年提高,水源涵养、废物处理和娱乐文化服务功能增强,而土壤形成与保护、食物生产服务功能明显减弱;生态服务价值高值区主要分布在沿江湖泊和湿地,其次是林草地覆盖区,青海高原荒漠区生态服务价值最低。
英文摘要	Based on the remote sensing monitoring data of land use in 2000,2005,and 2010, we utilized GIS technology to analyze the change mode, process and regional characteristics of land use in the Yangtze Basin and changes of ecosystem service functions. The results showed that from 2000 to 2010, a significant increase was present in the areas of urban and rural construction lands,woodlands and water s while the area of arable lands and grasslands continued to reduce. The reduction of arable lands was related to the increase of urban construction lands; while reduction of arable lands and grassland s was a result of increase in woodland; increase of water area was assocaited with Three Gorges water storage and returning farmland to the lake. Land use in hot spots of human activities like Sichuan Basin, midstream urban agglomeration and Yangtze Delta urban agglomeration obviously enhanced. Affected by changes of land use, the total value of ecosystem services in Yangtze Basin continued to increase from 2000 to 2010,with strengthened water conservation, waste management and entertainment and cultural services while soil formation and protection, good production and service functions were significantly weakened. High-value ecological service areas mainly included areas along lakes and wetlands, followed by areas covered by woodlands and grasslands. Tibetan Plateau desert area embodied the lowest ecological service value.
