摘　　要：应用综合指数法研究南水北调中线工程通水前后其沿线区域的生态环境状况变化趋势,分析距离水源地由近及远的生态环境变化情况,剖析距离干渠由近及远的生态环境影响强弱差异并识别影响显著地域。结果表明:1)通水前后,中线干渠3 km缓冲区域的生态环境状况整体呈好转趋势;2)远离水源地区域的生态环境改善幅度普遍优于靠近水源地区域;3)随着远离干渠,沿线区域生态环境影响逐渐减弱,且干渠1.5 km缓冲区内生态环境受到的影响最大。本研究可为南水北调中线工程通水后的生态效益评估提供参考,也可为工程沿线区域生态环境变动监测、生态环境改善措施制定提供依据。The comprehensive index method is used to explore the change trend in eco-environment of areas along the middle route of South-to-North Water Transfer Project before and after the project operation. The changes in eco-environment is analyzed with the increase of the distance from the water source. The differences of the impact of the distance from the main canal on the eco-environment is analyzed, and the areas with significant impact is discussed. The results show that:(1) It shows the slight improvement trend in the eco-environment of 3 km buffer zone of the middle route trunk canal;(2) The improvement of eco-environment in the region far away from water source is universally better than that in the region near water source;(3) With the increase of the distance from the main canal, the impact on the eco-environment weakens, and the eco-environment within the 1.5 km buffer zone of the main canal is greatly affected.This study can not only provide a reference for the evaluation of ecological benefits after the opening of the middle route of the South-to-North Water Transfer Project, but also provide a basis for formulating measures to improve the eco-environment and monitoring the changing areas of the eco-environment.
