关于云南利济河健康状况评价的探索研究

Exploratory Study on Health Status Evaluation of Liji River in Yunnan province

城市河流的健康状况是河道实现生态系统正常运转和社会服务价值的关键因素。以云南滇东北地区昭通市利济河为例,根据河流的自身特点并参考国内外已有相关研究构建了包含物理结构、水文水质、生物状况、社会服务和管理状况等5个要素12个指标的河流健康评价指标体系。并以2019年作为评估年,对利济河的河流健康状况进行了评价,结果显示除利济河上游河段河流健康状况处于三类河流(亚健康状态)外,其余河段仅为四类河流,处于不健康状态,亟需对河流进行整治,提升河道健康度。

The health of urban rivers is the key factor to realize the normal operation of ecosystem and the value of social service.Taking Liji River in Zhaotong city,northeast Yunnan province as an example,a river health evaluation index system was established,which included 5 elements and 12 indicators,such as physical structure,hydrology and water quality,biological status,social service and management status according to the characteristics of the river and referring to the relevant studies at home and abroad.The health status of Liji River In 2019 was evaluated.The results showed that the health status of the upper reaches of Liji River was in the third class(sub-health state),and the rest of the river was only in the fourth class,which was in an unhealthy state.It was urgent to improve the health status of the river.
