长江截流后三峡库区水环境质量对比及预测

该文利用1997—2001年三峡库区地面水质监测数据，分析三峡库区及施工区水环境质量，重点分析了1997年大江截流后的二期施工对施工区内干流水质及对长江干流水质的影响，施工建设只对施工区内干流水质略有影响，尚未对长江干流水质造成明显的不利影响，预测由于三峡建设所造成的区域水环境影响。

Comparison and Forecast Analysis of Water Quality in the Three Gorges Afterward the Cutting of Yangtze River

Using the monitoring data of water quality from 1997 to 2001, the water quality is analyzed in the reservoir and construction section of three gorges, among which the effect to the water quality of the afterward cutting and the second construction section is emphasized, and draw the conclusion: the construction only affects the water quality of the construction section lightly, do not affect the Yangtze River main branch obviously; and on the basis of it the article draws the conclusion which influence the water quality: industry waste water, the sewage of the urban living, surface runoff and the sewage from the watercraft. On the analysis of the water quality, the forecast of the regional water quality result from the construction of three gorges is taken into action.
