摘要: 城市河流健康状况直接影响到人们的生活质量,因此其修复问题也越来越受到关注。研究通过对修复后的转河进行实地调查,共选择10个调查样点,以气味、流速比、水深比、河岸的坡度、坡长、河宽、河岸材质、河床材质、植物种类和盖度、底栖生物的多样性指数、防洪功能、公众满意程度、可亲水度为评价指标,并结合权重分析法和专家打分法确定各指标的权重,对转河的修复效果作出评价。经分析得出转河的综合评价得分为2.75,属中上等水平。其中,上游河段评分较高,修复措施完善,河流生态功能和社会功能基本恢复;下游河段评分较低,主要是受地形影响,河流两岸仍是竖直硬质护岸,阻隔河水交换,进而影响河流水质和生物多样性的恢复。

Abstract: Since urban river health affects the quality of citizen’s life, river restoration has received increasing concerns. A field survey on Zhuanhe River which had been restored was carried out and ten sampling points were selected. Investigation factors including odor, flow speed ratio, water depth ratio, bank slope gradient, bank slope length, river width, bank protection material, riverbed material, plant species and coverage, benthos diversity index, flood control function, public satisfaction degree, and water closeness degree were chosen as evaluation indexes. Weighted analysis method combined with expert scoring method were emloyed to determine the weights of the indexes and to assess the restoration result. Results showed that the comprehensive assessment score was 2.75 which is better than average level. In detail, the score of the upstream was higher than that of the downstream, which indicated that the measures in the upstream are more complete and the river’s ecological function and social function have better recovered in the upstream; while in the downstream, due to terrain influence, vertical hard bank revetment can cut off the water exchange and further affect the recovery of river water quality and biological diversity.
