汉江是长江最大的支流,汉江中下游地区是汉江流域经济发展的中心。南水北调中线工程以及配套工程的实施,一方面给工程沿线地区带来了发展机遇,另一方面,南水北调中线工程也给汉江中下游带来了负面影响。由于调水影响,汉江中下游的水流量和水环境容量将减小,汉江水质,生态环境将面临新的问题;应该充分全面认识南水北调中线工程对汉江中下游地区的影响,加快四项配套治理工程,即引江济汉、兴隆枢纽、局部航道整治、部分闸站改造工程的建设,以减少调水造成的不利影响。
Hanjiang River is the largest branch of Yangtze River, and its middle and lower reaches are the center of economic development in Hanjiang River basin. The Median-line South-to-North Water Transfer Project and its corollary projects will bring on the developing opportunities on one hand, and on the other hand, will also bring on negative impacts to the linear areas of the project, Due to the water transferring, the water flow volume and water environmental capacity in the middle and lower reaches of Hanjiang River will be reduced, and its water quality and ecological environment will face with a new problem. So, it is necessary to pay attention to the effects above-mentioned and speed up the construction of four corollary improvement projects in order to reduce the unfavourable effects caused by the water transferring.
