水土流失对清林径水库水质的影响研究

Effect of Soil and Water Loss on Water Quality of Qinglinjing Reservoir

水土流失对水库水质的影响是多方面的。研究结果表明，水土流失对清林径水库最主要的影响是：水体感官混浊度指标与降雨强度呈正比；水土流失的营养盐进入水体，水质接近营养化水平，水土流失严重区域，水质呈中－富营养化水平，微生物含量明显增多。整体水质呈下降趋势。

There are multiaspects influence of soil and water loss on water quality of reservoir. The results have showed that the most important effect of soil and water loss on Qinglinjing reservoir is as followes: The turbidness index of water body shows direct ratio relation with intensity of rainfall. When nutrient salt is brought by soil and water loss into water body, the water quality is near nurtured level, while in severe area of soil and water loss, shows middle-rich nurtured level, the amount of microorganizm increase obviously. The whole water quality shows a tendency to deteriorating.
