摘要
水环境容量核算是城市水环境管理的基础。分析了北海市水环境特征的现状,通过划分陆域控制单元和对应水环境容量核算单元,根据设计水文条件及功能区水质目标等参数,综合选用一维河流非感潮河段容量计算模型、一维河流感潮河段容量计算模型核算了北海市各主要流域地表水水系的水环境容量。在此基础上,结合近海海洋环境容量,核算各控制单元点、面源负荷排放量,分析了北海市基于控制单元分区的可利用水环境容量空间分布特征,并提出了容量资源分区控制利用对策建议。
The water environmental capacity calculation was essential for the water environmental protection.By analyzing the water environmental features of Beihai City,the land control units and the corresponding water environmental calculation units were divided.On the basis of the hydrologic condition design and the target of water quality protection,one-dimension water environment capacity models for the normal reach and tidal reach were selectively applied to calculate the water environmental capacity of each river respectively.Considering the offshore environmental capacities,the available environmental capacity for each control unit of Beihai City was evaluated base on the current loads of point and non-point pollutant sources within the unit.Finally,the pollution control measures were put forward.
