摘　　要：每年的 3— 6月份 ,东牙溪水库表层水出现大面积的偏碱性污染的现象。调查发现水体中 p H值与氨氮、溶解氧和水温等指标具有显著的相关性 。The phenomenon of large-area meta-alkalescence pollution appears in superficial water of Dongyaxi reservoir in every year from March to June.The investigation shows that it possesses remarkable relativity between pH value and the indexes such as NH-3-N,DO and water temperature in water and consistence between the regularity of pollution and strong photosynthesis characteristics of planktonic algae.
