松滋市水功能区纳污能力核算与分析

摘要：结合湖北省松滋市水功能区划成果、现状水质情况、点源面源污染源类型及排污口特征，分别采用河流水功能区纳污能力零维、一维水质模型，核算与分析松滋市水功能区纳污能力。相关研究成果可为松滋市河湖长制的实施及水污染防治工作的开展提供一定的参考。

Abstract： Based on the results of the water functional zoning， the current water quality situation， the types of point source and non-point source pollution sources， and the characteristics of sewage outlets of Songzi city， Hubei province， zero dimensional and one-dimensional water quality models of river water functional zones were used to calculate and analyze the pollutant carrying capacity of Songzi city’s water functional zones. The relevant research results can provide certain reference for the implementation of the river and lake chief system and the development of water pollution prevention and control work in Songzi city.

Keywords： water function zone ; water quality compliance rate ; pollution holding capacity; one-dimensional model

水功能区纳污能力是指在满足水域功能要求的大前提下，并在给定的设计基础水文条件、水功能区水质目标、入河排污口位置及排污方式的情形下，水功能区水体所能容纳的最大污染物量。（剩余2945字）
