摘    要:本文论述了溶解氧、pH、温度和沉积物中微生物作用对太湖五里湖区沉积物磷释放的影响,以及在pH为8.4、好氧和厌氧二种状态下沉积物释放试验后滤液对斜生栅列藻(Scende es(?) obliq(?))和羊角月芽藻(Selena(?) ca(?))增长的影响.结果表明:溶解氧降低、pH和温度升高、微生物作用有利于沉积物磷向水体释放,与湖水组相比,厌氧状态下沉积物磷释放后滤液能显著促进斜生栅列藻增长,但不能促进羊角月芽藻增长,好氧状态下沉积物磷释放后滤液均不能促进二种藻类的增长。

关 键 词:沉积物  磷释放  藻类生长  五里湖  环境因子

Abstract:This paper studies the effects of DO, pH, temperature and the growth of bacteria on the release of phosphorus from Wuli Lake sediment. The result of experiments shows that the quantity of phosphours released from sediments into the water body was getting greater with decrease in DO, pH, temperature but increase in the growth of bacteria. The filtrate of the anaerobic release test may stimulate the growth of Scend esmus obliquus , but not the growth of Selenastrum capricornutum . It is showed that filtrate of the aerobic release test can stimulate neither of the algae.
Keywords:Phosphorus release from sediments  algae growth  Wuli Lake  sediment
