摘要

通过底泥正交模拟实验分析认为,温度、溶解氧、pH值和水动力均是影响双龙湖底泥磷释放的显著因素,各因素水平间有显著差异;影响因素显著性排序从大到小依次为溶解氧、温度、pH值、水动力;提高双龙湖水体的溶解氧水平是降低底泥磷释放的有效手段。

Abstract

The effects of environmental factors (temperature, dissolvable oxygen, pH and stir power)on release of phosphorus from sediment in Shuanglong Lake were analyzed by the orthogonal experiment. It is concluded that temperature, dissolvable oxygen, pH and stirpower are all remarkable affecting factors in phosphorus releasing, and every level of factors has remarkable difference. The order of marked factors from large to small is dissolvable oxygen, temperature, pH, stir power. It is a effective measure to improve level of lake′s dissolvable oxygen to reduce phosphorus releasing in sediment.
