蔚蓝城市水环境指数使用IPE收集的国家和地方地表水水质监测断面水质评价数据,经过加权赋分计算,再根据分数段划定等级,数值越高代表水环境质量越好。
Note: The ranking of Ground Water Quality Ranking is based on CWQI, calculated using the national surface water quality monitoring section data released by the Departments of Ecology and Environment. The data is for reference only.
The calculation method is based on the Technical Regulations for Urban Surface Environmental Quality Ranking (Trial). The lower the data, the better the water environmental quality.
