中国的南水北调工程是有史以来规模最大的南水北调工程。在它的三条线路(即东、中、西)中，到2030年，中线每年将从长江支流汉江和供水区向北京调水140亿立方米。因此，汉江上游9.5万平方公里的水质非常令人担忧。流域管理倡议已在流域内实施，最终目标是量化流域的生态系统功能，并制定水资源保护的综合管理系统。具体而言，该方案包括五项活动：确定河岸生态系统的特征，探测土地利用和土地覆盖变化，量化典型生态系统的营养循环，确定水质的时空变化，以及开发水资源保护的分水岭管理系统。本文阐述了流域治理的合理性，并对汉江流域水资源保护的初步成果进行了分析。
The South-to-North Water Transfer (SNWT) Project of China is the largest of its kind ever implemented. Of its three routes (i.e., East, Middle and West), the middle one will transfer 14 billion m3of water annually from the Han River, a tributary of the Yangtze and the water supplying area, to Beijing by 2030. Thus water quality in the 95,000 km2upper Han River basin is of great concern. A watershed management initiative has been implemented in the basin, and the ultimate objectives are to quantify basin’s ecosystem functioning and to develop an integrated management system with respect to water resources conservation. Specifically, the program includes five activities: characterization of riparian ecosystems, detection of land use and land cover change, quantification of nutrient cycling of representative ecosystems, determination of spatial and temporal variations of water quality, and finally development of a watershed management system for water conservation. This article provides the justifications of the watershed management initiative and the initial results are comprehended with respect to the water conservation in the Han River basin.
