摘　　要：在西北干旱地区,城市河道是城市的生态线、生命线、景观线。如何开展城市河道景观工程建设管理绩效评估是河道建设保证城市河道生态水文安全、改善人居环境质量、提升城市河道可持续发展能力的关键科学问题。以西北干旱地区国家级园林城市库尔勒市为例,基于全生命周期理论、扎根理论和ANP法,首先从规划设计、建设实施、绿化养护三个阶段构建了城市河道景观工程可持续建设管理绩效评价体系;其次,基于可拓物元法对库尔勒市杜鹃河景观工程可持续建设管理绩效进行评价,确定评价等级为"良";最后,依据评价结果提出库尔勒市河道景观工程可持续建设管理提质增效策略,可为其他城市河道景观工程建设实践提供参考。In arid areas of the northwest China,urban rivers are the ecological line,lifeline,and landscape line of the city.How to carry out performance evaluation of urban river landscape construction is a key scientific issue to ensure the ecological and hydrological safety of urban rivers,improve the quality of human settlements and enhance the sustainable development of urban rivers.Based on the whole life cycle theory,grounded theory and ANP method,taking Korla—a national garden city in the arid area of northwest China,the sustainable construction management performance of urban river landscape engineering was constructed from three stages:planning and design,construction and implementation,and greening and maintenance.Then,based on extensible matter-element method,the sustainable construction management performance of Dujuan River landscape project in Korla City was evaluated,and the evaluation level was determined as good.Finally,based on the evaluation results,the strategy of improving the quality and efficiency of the sustainable construction management of river landscape project in Korla City was proposed,which aims to provide reference for construction of other urban river landscape projects.
