南水北调中线工程与汉江中下游地区相互影响分析

随着社会、经济和人口的发展，需水量不断增加，中国北方地区水资源紧缺严重地限制社会和经济的发展。南水北调中线工程从丹江口水库调走部分水量，在解决我国北方地区缺水问题的同时，也在一定程度上改变了汉江中下游地区水资源供需关系。从水资源可持续利用的角度，系统地分析了南水北调中线工程和汉江中下游地区水资源利用相互关系。在此基础上，提出了南水北调中线和汉江中下游干流供水区水资源可持续利用的对策建议。

ANALYSIS ON THE INTERACTIVE EFFECTS BETWEEN THE MIDDLE ROUTE OF SOUTH-TO-NORTH WATER TRANSFER PROJECT AND THE MIDDLE AND LOWER BASINS OF HANJIANG RIVER

Due to increasing acceleration of both economic development and population growth, water consumption and requirement have increased greatly since the 1980s, and water shortage in northern China has become a major factor constraining economic and social development. The middle route project transfers some water from Danjiangkou reservoir, but it changes the relationship of water resource utilization in water source region when resolving water shortage problems in north China. Emphasizing sustainable water resource utilization, the analysis of the relationship between the basins and the middle route project are discussed in detail. Finally, some advices are given to ensure the sustainable utilization of water resource in the two regions.
