摘　　要：从河流功能属性出发将河流功能分为自然、生态、社会服务三类,构建了城市河流综合功能评价指标体系和确定评价标准。根据该体系、评价标准特点,为了避免权重过于主观或客观,选用信息熵法和可拓法构建了信息熵可拓评价模型,并应用到淮河干流蚌埠段进行实例评价。评价结果能较好地反映该段河流综合功能的实际情况,说明指标体系及标准合理,评价方法可行,可为进一步研究城市河流功能提供借鉴,为城市河流的开发利用、灾害规避和河流控制等工作提供决策依据。Based on the river function attribute,the river function is divided into three categories:natural,ecological and social services,a comprehensive function evaluation index system is constructed and evaluation criteria of urban river is determined.According to the features of the system and evaluation criteria,in order to avoid the weight being too subjective or objective,the entropy-extension model was built by using the information entropy method and matter-element extension method,and applied to the Bengbu reach of main stream of Huaihe River for example evaluation.The actual situation of the comprehensive function of this river section can be reflected from the evaluation results,indicating that the index system and criteria are reasonable and the evaluation method is feasible.It provides reference for further study of urban river function,decision-making basis for the development and utilization of urban rivers,disaster avoidance and river control.
