摘要
根据景观水体的补水情况、水质变化情况,通过控制不同温度和不同的上覆水水质来模拟底泥释放试验说明景观水体的污染源特性、底泥释放污染物(营养盐N、P、CODMn)的规律。得出了温度和上覆水质对底泥释放的影响曲线。同时也说明景观水体内源磷对景观水体的水质存在着潜在的危险性,为预测景观水体的水质变化情况和换水或补水量、补水时间的确定提供必要的依据。
According to the situation of supplement water and water quality change, the release experiment of sediment was made by the main control of different temperatures and different water on sediment. The study on release experiment of sediment showed characteristics of pollution source （nutrient N, P, CODMn ） and the rules of sediment release. The effects curve of temperatures and different water on sediment on sediment release were got. It also indicated that endogenous phosphorus of landscape water exist potential risk, and the necessary basis was provided for prediction of the water quality of landscape water, and determination of the capacity of fill water and time of fill water.
