河渠水环境容量研究——以成都市为例

Water Environment Quality Planning for River Channel--A Case Study of Chengdu City

以成都市外环路生态保护带以内的598km2中心城区的地表水体为研究对象。在综合考虑城市防洪、水资源综合利用以及城市经济发展条件等基础上,对其水体环境质量现状进行评价,确定了河道水体的主要污染因子;对规划区内河道水体的环境容量进行核算,提出各规划期限内需削减的城区水体污染源污染量。

Surface water body of urban centre with 598km2 in Chengdu City,Sichuan Province was studied.Based on urban flood control,water resource and economic development,the existing water quality was assessed and pollution parameters of rivers were identified.Accounted on environment capacity of river in the proposed urban area,water pollutant emission that needed to reduce in various planning terms was proposed.
