摘　　要：城市化是城市河流生态系统退化的重要驱动力,也是城市河流生态恢复的限制因素.为针对城市河流的实际情况,确定河流的生态恢复目标,避免浪费人力、物力,在已有成果的基础上,研究了城市不透水表面比率对河流生态的影响,以不透水表面比率为评价依据,选取不同评价因子,初步构建了退化城市河流生态恢复能力评价体系,依据评价等级确定了各指标的评价标准,为制定具体的河流修复目标及选择相应措施提供了重要依据.Urbanization is an important driving force to the ecological degradation of urban river;meanwhile it is also a limiting factor to the river restoration.According to the actual situations of urban river,the ecological restoration targets should be determined.In order to avoid waste of manpower,material resources,this paper analyzes previous studies,and studies the impact of the urban impervious surface ratio on river ecology.The impervious surface ratio is used as the evaluation element and different evaluation factors are selected,we initially construct the ecological restoration evaluation system of ecologically degraded urban rivers and determine the evaluation criteria of each index.This study can help developing river restoration programs,and selecting the appropriate goals and measures.
