《南水北调与水利科技》:引江济汉工程对汉江中下游生态环境影响(王婷婷,张万顺,彭虹,朱齐艳,张斌)(摘要)

摘要:引江济汉工程作为南水北调的配套工程,将在改善汉江中下游生态环境方面发挥不可忽视的作用。基于河流水质模型及河流综合水质生态模型从水文、水质、鱼类、藻类及血吸虫病传播等方面,论述了引江济汉工程的实施对汉江中下游生态环境的影响。研究结果表明:引江济汉工程在一定程度上提高了汉江中下游的水位和流量,降低了汉江中下游水体的污染物(COD)浓度,能够在一定程度上控制“水华”现象,改善鱼类的生存空间,但同时也存在造成血吸虫病传播的潜在风险。

Abstract:The water transfer project from Yangtze River to Hanjiang River,as a matching project of the South-to-North Water Transfer will make a great effect on the eco-environment of the middle and lower reaches of Hanjing River.The paper analyzes its effect on the ecosystem environment from the aspects of water level,flow,growth of fish,algae based on the water quality model and the RQEM. The results show that after the water transfer project,water level and the capacity of the middle and lower reaches of Hanjiang River will be enhanced,the concentration of the water pollutant (COD) will be reduced,the "water bloom" phenomenon will be controlled,fish""s survival space will be improved,but the potential risk of schistosomiasis diffuseness may be increased.

Key words:the water transfer from Yangtze River to Hanjiang River;the midddle and lower reaches of Hanjiang River;eco-environment
