拒马河河流形态结构健康现状调查与评价

Investigation and evaluation of health status of river morphology and structure in Juma River

根据拒马河河岸带现状的调查数据,运用河流形态结构完整性评估指标体系,对拒马河形态结构健康现状进行了评估。本次评估将拒马河分为紫荆关、都衙和张坊三个河段,结果表明:拒马河的河流纵向连通指数、河岸带植被覆盖度、河岸带人工干扰程度等三个基本指标评分都相对较低,导致拒马河形态结构完整性处于不健康的状态。针对拒马河形态结构健康现状提出以下保护对策:清理河道垃圾,河岸种植植被;加强宣传教育力度,增强民众保护意识。

Based on the investigation data of the riparian zone of the Juma River, the morphologically health status of the Juma River was evaluated by using thestructural integrity assessment index system of river morphology and structure. This assessment divided the Juma River into Zijingguan, Duya and Zhangfang river reach. The results showed that the vertical connectivity index, riparian vegetation coverage and riparian artificial disturbance were all relatively low, which led to the unhealthy morphological and structural integrity of the Juma River. In view of the morphologically health status of the Juma River, the following protection measures are put forward: cleaning up the river wastes and planting vegetation on the river bank;strengthen publicity and education efforts to enhance the public’s awareness of protection.
