中文摘要	以京津风沙源区生态系统结构、质量和服务功能分析了一期治理工程的生态效应,结果表明: 1) 2010年草地生态系统占全区面积的63.29%,十年间林地面积增加了0.22万km~2, 草地面积减少了0.17万km~2; 2)工程区十年间植被覆盖总体呈现好转态势,植被覆盖度转差的面积占全区面积的19.36%; 3)工程区土壤风蚀以微度和轻度侵蚀为主,十年间土壤风蚀量总体呈现下降态势,荒漠草原亚区下降最为明显,倾斜率为- 3.15t·hm~(-2)·a~(-1)。京津风沙源区整体生态状况趋于好转,一系列生态工程的实施对于恢复自然植被和提升生态系统防风固沙服务功能起到了积极作用。
英文摘要	We analyzed ecological effects of Beijing and Tianjin sandstorm source control project in the first stage through ecological system structure,quality and service function. The results showed that: (1) Grassland was the main ecosystem type in Beijing and Tianjin sandstorm source control project area,with the area ratio of 63.29%. Forestland area was increased 0.22 * 10~4 km~2 from 2000 to 2010,while grassland area was decreased 0.17 * 10~4 km~2. (2) Vegetation coverage of project area was overall improvement. The area proportion that vegetation coverage degenerated was 19.36%. (3) The intensity of soil wind erosion was primary mired and mild. Soil wind erosion amount was overall showed downtrend in the past ten years. Desert grassland sub region was declined most apparently,with the slope rate of - 3.15t·hm~(-2)·a~(-1). Ecological status of the project area was overall changing better. The implementation of a series of ecological projects had positive effects on recovering natural vegetation and promoting soil retention service function.
