摘要
重点分析了底泥营养物的分层分布对湖泊水质的影响强度 ;模拟了复水过程底泥内营养盐中的磷的释放规律 ;建立了上覆水中磷浓度变化对界面物质交换的影响方程。模拟分析研究表明 ,分布在底泥沉积物的无机态营养盐在较长时间内都将持续影响湖体水质 。
Xue Lianqing1,2 Lu Xiwu1 Wu Lei1(1.Civil Engineering College in Southeast University, Nanjing Jiangsu 210096; 2.Water Resources and Environment College in Hohai University, Nanjing Jiangsu 210098)The research on the influence to lake water quality of nutrient layer distribution in sediment was emphasized. The release process of phosphorus was simulated and the interface material exchanging equation caused by covered water phosphorus concentration changing was built. The research results indicated that the inorganic sediments in sediments will affect the lake water quality sustainable for a long time. The experiments benefit to the construction regulation and eutrophication prevention.
