摘要:

太子河作为本溪的主要河流,是本溪工业、农业、生活的主要水源,为了更好的了解太子河本溪城区段的水体情况,以太子河本溪城区段流域为研究对象,基于2017年的平水期(4月)、丰水期(8月)、枯水期(11月)18个监测断面的监测数据,结合太子河本溪城区段的实际情况和特点,利用层次分析法的评价指标体系,对太子河本溪城区段进行水生态系统健康评价。通过比较分析,最终以平水期的评价结果为主,丰水期和枯水期的评价结果为辅。结果表明:仅有22%的监测断面处于健康状态、56%的监测断面处于亚健康状态、22%的监测断面处于一般状态,说明太子河本溪城区段大部分流域处于亚健康状态,水生态系统退化,需要加强管理和治理保护。

Abstract:

As the local main river, the Taizi River is the primary source for industrial, agricultural, and living water in Benxi.In order to better understand the water body condition of Taizi River in the urban area of Benxi, based on the data of 18 monitoring sections in the seasons of average water (April), abundant water (August) and the lack water (November) in 2017, combining with the actual situation and characteristics of the studied river section as well as the use of the evaluation index system of Analytic Hierarchy Process (AHP), the health of water ecosystem of the studied river section was evaluated.With the comparison and analysis, the evaluation result in the average water season is taken as dominate part and those in the abundant water season and lack water season are taken as auxiliary.The results show that only 22% monitoring sections are in a health condition and 56% ones are in a sub-health status, while the other 22% monitoring sections are in general status, which reflects that the most basin of Taizi River flowing through Benxi urban area is being in the sub-health state and its water ecosystem is deteriorating, revealing that reinforcing management and protection is needed in the studied river section.

Key words: Water ecosystem health, Taizi River flowing through Benxi urban area, Analytic hierarchy process (AHP)
