摘要: 基于工业污染源普查数据,采用缓冲区分析和热点分析法,分析冀西北张家口市工业点源空间分布格局,结果表明:(1)工业点源集中分布在以主城区为中心的东南—西北轴上的邻近区县。张北县和宣化区工业点源污染负荷最重。(2)工业点源在永定河水系分布最多,并在洋河流域形成带状分布,高负荷工业点源分布具有临河性、临城性,污染物排放高密度区在张北县、宣化区和万全区。(3)大型、中型、小型和微型企业都主要集中分布在坝下永定河水系,其次是内陆河水系。重度污染行业集中排放源分布在张北、沽源和康保县,轻度污染行业集中排放源分布在坝下永定河水系中洋河与清水河交汇处。通过分析工业点源空间分布格局,以期为政府部门调整规划工业和重点治理水污染区提供依据。

Abstract: This research analyzes the spatial distribution pattern of industrial point sources and pollution loads in Zhangjiakou city, a central city in the northwest of Heibei province by buffer analysis and hotspot analysis, based on sewage industrial point source information database. The results show that: (1) Industrial point sources are concentrated in neighboring districts on the southeast-west axis of the main urban area. The industrial point source pollution of Zhangbei county and Xuanhua district are the heaviest. (2) Industrial point sources are mostly distributed in the Yongding River system, presenting a banded distribution in the Yanghe River Basin. The high load of water pollutant of industrial point sources is near the river and the city, and high density areas of pollutant discharge are concentrated in Zhangbei county, Xuanhua district and Wanquan district. (3) The large, medium, small and micro enterprises are mainly concentrated in the Yongding River system under the dam, followed by the inland river system. Major emitters of heavily polluting industries are mainly located in Zhangbei, Guyuan and Kangbao county, and major emitters of light pollution industries are concentrated in the intersection of Zhongyang River and Qingshui River in the Yongding River system under the dam. By analyzing the spatial distribution pattern of industrial point sources and their pollution load characteristics, this study can provide guidance for government departments to adjust planning industries and focus on water polluted areas.
