Data on the status of water bodies in the river category

The compilation provides an assessment of the ecological and chemical status of water bodies in the river category, based on national environmental monitoring data or expert judgement. The ecological status is determined on the basis of indicators of physico-chemical, hydromorphological and biological quality elements, in accordance with the methodology for determining the status of surface water bodies. The chemical status was determined in accordance with the Waste Water Management Regulation.本数据集汇编基于国家环境监测数据或专家研判，对河流类水体的生态与化学现状开展评估。生态现状依据地表水水体现状评估方法，通过理化、水文形态及生物质量要素指标进行判定；化学现状则按照《废水管理条例》完成判定。
