【摘要】：实施水功能区限制纳污红线管理,控制陆域范围污染物排放总量,是保障水功能区水质达标的根本途径。针对现有水功能区划分及管理偏重考虑水体自然属性和完整性,缺乏与行政区划、陆域污染源分布的衔接,提出以水功能区划分成果为基础,综合考虑自然水系、行政区划、污染源分布情况的陆域控制单元划分方法,在此基础上,利用GIS空间分析建立水功能区与陆域控制单元的响应关系,制定基于水功能区纳污能力的陆域污染物限制排放总量方案。以攀枝花市河段为例,将攀枝花市划分为15个控制单元,19个控制子单元进行限制排污总量计算及分配,攀枝花全市COD、氨氮限制排放总量分别为17 437.6 t/a、1 866.0 t/a,与攀枝花市污染物总量控制规划成果基本一致。
[Abstract]:It is the basic way to ensure the water quality of the water function area to limit the red line management and control the total pollutant discharge in the land area.In view of the fact that the existing water function areas are divided and managed with emphasis on the nature and integrity of the water body, lacking the connection with the administrative division and the distribution of the pollution sources in the land, the paper puts forward that based on the results of the division of the water function areas, the natural water system and the administrative division should be considered synthetically.On the basis of the division method of land area control unit for the distribution of pollution source, the response relationship between water function area and land area control unit is established by using GIS space analysis.To formulate a scheme for limiting the total discharge of pollutants in the land area based on the capacity of water function areas to absorb pollution.Taking the Panzhihua River reach as an example, the Panzhihua City is divided into 15 control units and 19 control subunits to calculate and distribute the total amount of limited sewage discharge.The total emission of COD and NH3-N in Panzhihua was 17 437.6 t / a / a, 1 866.0 t / a respectively, which was consistent with the results of total pollutant control planning in Panzhihua city.
