摘要
河流健康评价是开展流域规划、系统治理和生态修复工作的基础。廊坊龙河下游河段生态脆弱,水体流动性差、水环境状况不容乐观。为准确评价人类活动严重干扰下的河流生态健康状况、识别生态系统中脆弱性因子,基于层次分析法构建龙河下游健康评价指标体系,从水文完整性、物理结构完整性、化学完整性、生物完整性、社会服务功能完整性5个方面进行河流健康评价。龙河廊坊段总体上处于健康状态,评价得分为75.18分。评价结果表明:龙河流域水资源开发利用率大,湿地保留状况不佳,河岸带人工干扰程度大,上游来水水质较差等。提出的评价方法为受人工控制严重的河流开展健康评价提供方法参考。
River health assessment is the basis for watershed planning,systematic treatment,and ecological restoration.The lower reaches of the Longhe River in Langfang suffer fragile ecology and lack water fluidity,showing a poor water environment.To accurately assess the ecological health of rivers severely disturbed by human activities and identify the fragility factors in the ecosystem,we construct a health assessment index system for the Longhe River based on the analytic hierarchy process(AHP).The river health assessment index system consists of five aspects:hydrological integrity,physical structural integrity,chemical integrity,biological integrity,and social function integrity.The Langfang section of Longhe River is generally in a healthy state with a health assessment score of 75.18.According to the assessment results,the Longhe River watershed has problems such as large development and utilization of water resources,low wetland retention rate,serious artificial disturbance in the riparian zone,and poor quality of the upstream water.The proposed assessment method could provide a reference for the health assessment of rivers under severe artificial control.
