- 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 which is a tie in project of the South-to-North Water Transfer,will make a great effect on the improvement of the eco-environment of the middle and lower reaches of Hanjiang River.Based on the water quality model and the RQEM,the effect of the water transfer project from Yangtze River to Hanjiang River on ecosystem environment of the middle and lower reaches of Hanjiang River is analyzed from the aspects of water level,flow,growth of fish,algae,etc.The results show that the middle and lower reaches of Hanjiang Rivers water level and the capacity enhance in a certain degree,the concentration of the water pollutant(COD) reduces,the "water bloom" phenomenon is controlled in a certain degree,fishes’ survival space has been improved,however there also exists the spread of schistosomiasis potential risks after the water transfer project from Yangtze River to Hanjiang River.
