九龙江流域湖库化河段水环境容量研究

Abstract

针对九龙江流域湖库化问题,确定湖库化河段判定标准,提出综合电站的概念,基于大量的实测数据进行水质模型的降解系数值k参数率定,以此为基础,提出湖库化河段水环境容量计算方法,对九龙江流域湖库化后的水环境容量核算开展研究,确定了流域河流湖库化对水环境容量计算的影响,湖库化河段的水环境容量,为流域的水环境容量总量控制和管理、决策提供科学的依据.

According to the problem of reservoired in Jiulong River basin,the judgment standard of reservoired river was determined,and the concept of integrate hydropower station was presented.Then,the parameter value of degradation coefficient K was calibrated with water quality model based on a large number of measured data of water quality.On this basis,calculation method of water environmental capacity for reservoired river was proposed.Finally,research was carried on water environmental capacity accounting of reservoired river in Jiulong River basin.The results show the effect of reservoired on water environmental capacity calculation,and the water environmental capacity of reservoired river,which provided scientific basis for the total emission control,management and decision-making of water environmental capacity in Jiulong River basin.
