水体纳污能力是科学合理地制定水污染控制规划的基础.沿海河网地区水系复杂,水体具有水深较浅、流速缓慢、顺逆不定和水体自净能力不强等问题.以沿海平原河网地区的海门市水环境为研究对象,根据其水系特点和实际需要建立-维河网水量水质模型,在此基础上计算了该市主要河道的纳污能力,为当地的水环境管理提供科学依据.%Water environmental capacity was the foundation of establishing reasonable water pollution control planning. Due to the characteristics of shallow water depth, slow velocity of flow, inconstant direction of flowing water, and poor ability of self- purification, the river system was very complex in plain network regions. The water environment of Haimen City along the coastal plain network area was taken as research object. Based on water flow and pollution characteristics of plain network, a river network 1 - D hydraulic and water quality model was established by one dimensional advection. The water environmental capacity was calculated based on the model, which provided scientific basis for local water environmental management.
