南水北调东线一期工程水质分析

南水北调东线第一期工程90％的输水河道是利用现有河道．由于现有河道水环境问题突出，调水水质的好坏直接影响水资源的使用价值和沿线地区社会经济的发展，同时也决定调水工程的实际效益．在分析工程影响区域水污染来源及成因、水环境质量等因素的基础上，结合国家东线治污规划，预测调水水质，探讨东线的保护措施．

Water quality analysis for the first stage of South-to-North Water Transfer East Line Project

Ninety per cent of conveyance channels in the first stage of the South-to-North Water Transfer East Line Project take use of the currently existing river channels. Owing to the conspicuous water environment problem, the quality of water transfer is closely related to the value of water resources and social economy development along the line of the project, and is also a determinant factor to the benefit of the project. Based on an analysis of the sources of water pollution and the quality of water environment in the affected areas of the project, the quality of water transfer was predicted according to the national planning for pollution remediation along the east line of the project, and some measures for water environment protection were discussed.
