“创模”工作对城市水环境质量的影响--以贵阳市和遵义市为例

摘要

目前，贵州省贵阳市和遵义市通过了国家环保部考核验收，获得国家环境保护模范城市称号，本文拟以这两个城市为例，回顾了它们开展“创模”前后水环境质量的变化。结果表明，通过“创模”工作，两个城市水环境质量有了很大的改善，水体中主要污染物浓度得到了有效的控制，其浓度值呈下降趋势，表明“创模”工作对改善城市水环境质量有很大的促进作用。%Recently,Guiyang City and Zunyi City has been qualified as National Environmental Pro-tection Model Cities. Results from the analysis on changes of water quality in Guiyang City and Zunyi City before and after the application show that a gradual decrease in terms of major water pollutants has been witnessed during application period,and major water pollutants can meet relevant water quality standards thereafter,implying that implementation of tasks involved in applying for National Environmental Protection Model Cities can promote greatly the water quality.
