感潮河网中围区内河道水环境容量研究

Study on the Water Environmental Capacity of Rivers in the Surrounding Area of Tidal River Network

水环境容量是水资源规划管理的一个重要依据,为研究感潮河网中围区内河道水环境容量,分析了现有的水环境容量计算方法,根据感潮河网中围区内河道水文水动力特征,在感潮河网四典型流模式的水环境容量模型基础上,提出了基于一维动态水质模型解析解的单围区整体模式的水环境容量计算方法,并且成功应用于容桂联围内河涌水环境容量的计算。结果表明,该方法对于感潮河网中围区内河道水环境容量计算简便且有效。

Water environmental capacity is an important basis for water resource planning and management.In order to analyze the water environmental capacity of river channels in the enclosed areas of tidal river networks,the paper analyzes the existing methods for calculating water environmental capacity.According to the hydrodynamic characteristics of the river channels in the enclosed area of the tidal river network,Based on the water environment capacity model of the four typical flow patterns in tidal river networks,the paper proposes a method for calculating water environmental capacity using the analytical solution of a one-dimensional dynamic water quality model for a single enclosure overall model.And it has been successfully applied to the calculation of the water inflow environmental capacity of the Ronggui Lianwei River.The results indicate that this method is simple and effective for calculating the water environmental capacity of river channels within the enclosed area of tidal river networks.
