三峡水库蓄水后水质富营养化因素分析

Analysis on Water Eutrophication in Three Gorges Reservoir Area

以三峡水库175-145-155m蓄水方案出发,分析了水库蓄水后每年10月至次年5月的水流速度、均水深、氮和磷的浓度、生化降解速率以及三峡库区的自然环境和社会情况。分析表明,三峡水库175-145-155m蓄水方案,其水质每年10月至次年5月恶化的可能性较大,尤其是边滩及其回水河道的水质可能会出现季节性恶臭富营养化。

According to the 175-145-155m sluice project of TGRA.The author analyzed the water empress speed and average deep from annually October to the next year may,the nitrogen and phosphoric chroma, biodegradation and a serises negative influence of the enviroment ,the result indicated that water matter is annually October to the next year may,the worsen possibility is big,particularly in side pool and it'sreturuing the water course of river may appear seasonial eutrophication.
