松滋市水功能區(qū)納污能力核算與分析

摘要：結(jié)合湖北省松滋市水功能區(qū)劃成果、現(xiàn)狀水質(zhì)情況、點(diǎn)源面源污染源類(lèi)型及排污口特征，分別采用河流水功能區(qū)納污能力零維、一維水質(zhì)模型，核算與分析松滋市水功能區(qū)納污能力。相關(guān)研究成果可為松滋市河湖長(zhǎng)制的實(shí)施及水污染防治工作的開(kāi)展提供一定的參考。

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

水功能區(qū)納污能力是指在滿(mǎn)足水域功能要求的大前提下，并在給定的設(shè)計(jì)基礎(chǔ)水文條件、水功能區(qū)水質(zhì)目標(biāo)、入河排污口位置及排污方式的情形下，水功能區(qū)水體所能容納的最大污染物量。（剩余2945字）
