基于水交换的湖泊调蓄模式研究

Study on lake regulation based on water exchange theory

水交换强度与水体水质状况密切相关,通过水交换的分析计算可以对湖库进行合理调蓄,达到控制其生态、环境质量的目的。本文利用三维数值模型对所研究的湖泊进行了水龄的计算,分析了水交换强度的季节变化趋势和空间分布特点;同时结合数值实验,定量分析了不同调度模式对水交换时空分布的影响。最后给出了对湖泊调度模式的建议。

The intensity of water exchange is closed related to the water quality.The lake can be regulated properly according to the analysis of water exchange,its quality of ecology and environment can be controlled.By using the method of three-dimensional numerical model,the age of the water was calculated,and the seasonal change and spatial distribution characteristics of water exchange intensity was analyzed in this paper.Combing with the numerical experiment,the effect of different lake regulation mode on spatial distribution of water exchange was analyzed,and suggestions about how to operate the lake were given at the end of this paper.
