城市河道生态护坡综合评价指标体系研究

A Comprehensive Index System for Evaluating Ecological Revetments on Urban Riverbanks

阐述了城市河道生态护坡综合评价的基本内容,指出当前评价中指标体系建立的不足。认为评价指标体系的建立应科学合理地反映出所要评价的生态护坡系统的各项指标要求。建立了合肥市城市河道生态护坡评价指标体系,该体系的内容包括城市河道生态护坡类型及材料、稳定性、功能和社会经济效益4项指标要求,并采用层次分析法进行了工程实例分析,评价结果良好地反映了四里河和南淝河生态护坡的特性。该指标体系的建立,为合肥市生态护坡的评价奠定了基础,对城市生态护坡建设具有一定指导意义。

The basic concepts of comprehensive evaluation of urban ecological revetments were clarified,and the insufficiencies of current index systems for the urban ecological slope evaluation were exposed explicitly.An ideal evaluation index system should reflect,scientifically and reasonably,the requirements of an ecological protection system.Based on this concept,a comprehensive evaluation index system for the ecological revetments of Hefei City was developed.The system is consisted of four indices including types and materials of the construction,stability,functions,and social and economic benefits.The analytic hierarchy process（AHP） was then applied to evaluate engineering cases and the results were found reasonable.The system could provide a basis to evaluate ecological revetments in Hefei City and potentially significant guidance for urban revetment constructions.
