摘　　要：对南方三个典型梯级水库的水质和底泥状况调查研究发现,内源磷是三个水库中藻类暴发的主要诱因之一。通过控制单一环境因素的变化研究底泥中TN和TP的释放规律,结果表明,升高温度、厌氧条件均会加速水库底泥中TN和TP的释放;而好氧条件会抑制底泥中TN和TP的释放;增强光照可以加速底泥中TP的释放,但是对TN的释放影响不大。Through the survey of water quality and sediment in three cascade reservoirs in south China, it was found that endogenous phosphorus was one of the main causes of algae outbreak in the res- ervoirs. The release law of TN and TP in the sediment was studied by controlling the change of single en- vironmental factor. The results showed that high temperature and anaerobic conditions could accelerate the release of TN and TP. But aerobic conditions could inhibit the release of TN and TP. Illumination en- hancement could accelerate the release of TP, but it had little effect on the release of TN.
