川西林盘院落的地表径流低影响措施设计研究

Study on the Design of Low Impact,easures of Surface Runoff in linpan Courtyard of Western Sichuan

我国农村面源污染问题突出,引起了高度关注。林盘是川西平原上典型的一种与水相依的人居环境乡村聚落。随着川西平原乡村经济的发展,由村民生活导致的林盘院落地表径流水质污染日渐加重。在分析现有林盘院落空间与水渠关系的基础上,研究了川西林盘院落地表径流的来源、类型以及处理现状,根据林盘的规模,将其划分为大、中、小型林盘,并提出了适应不同规模林盘院落的低影响处理措施,为川西林盘院落地表径流的处理和都江堰灌溉水渠水质优化提供参考。

The problem of non-point source pollution in rural areas of China is prominent,which has attracted great attention.Linpan is a typical rural settlement with water dependent living environment in the West Sichuan plain.With the development of rural economy in Chengdu Plain,the surface runoff water pollution caused by villagers'life is becoming more and more serious.Based on the analysis of the relationship between the existing Linpan courtyard space and the water channel,this paper studied the source,types and treatment status of the ground surface runoff of the Linpan courtyard in Western Sichuan.According to the scale of the Linpan,it was divided into large,medium and small Linpan,and the low impact treatment measures were put forward to adapt to different scales of Linpan courtyard,which provides reference for the treatment of surface runoff of West Sichuan Linpan courtyard and the water quality optimization of Dujiangyan Irrigation canal.
