基于非点源污染空间机制的综合控制格局构建

Building of Integrated Control Pattern Based on Spatial Mechanism of Non-point Source Pollution

文章基于非点源污染扩散过程与空间格局的关系分析了非点源污染的空间机制,并从源头关键点—传输通道—汇前区3个层面出发,构建了由湿地、涝池、农田复合廊道系统及河岸植被缓冲带组成的综合控制格局;最后以秦岭北麓鄠邑段为例进行案例应用研究。研究揭示非点源污染的空间机制并构建空间优化格局,这对空间规划具有重要的现实意义。

This paper analyzes the spatial mechanism of non-point source pollution based on the relationship between non-point source pollution diffusion process and spatial pattern,and builds the integrated control pattern which is composed of wetlands,pond,compound corridor of farmland system and riparian vegetation buffer zone from the 3 levels from key points of source,the transmission channels and the areas before carbon sink.The case of Huyi Section of north foot of Qinling Mountains is taken to study and reveal the spatial mechanism of non-point source pollution and construct a spatial optimization pattern,which is of important practical significance for spatial planning.
