摘要
本文分析了城市水生态系统的主要服务功能：景观娱乐、污染物自净、环境调节、水文调节、补充水源。明晰了适应性、节水节地、多样性、连通性和协同性是城市水生态建设应遵循的主要原则。最后结合城市水循环的特征提出了3种新的水生态建设模式：（1）与经济社会水循环排水系统衔接的建设模式；（2）与自然水循环衔接的建设模式；（3）与生态闭路水循环系统衔接的模式。为改善城市水生态系统的科学管理提供了新的思路。
The main eco-service functions of an urban aquatic ecosystem is analyzed herein, i.e. landscape recreation, self-purification of pollutants, environmental adjustment, hydrological adjustment, water recharge, etc. , and then the relevant adaptability, land and water-saving, diversity, connectivity and cooperativity are clarified as the main principles of the construction of an urban aquatic ecosystem. Combined with the feature of the urban hydrological cycle, it is finally put forward the following 3 new patterns for the construction of the ecosystem ： 1. a new construction pattern coupled with the drainage system of the water cycle within a economic society ; 2. a new construction pattern coupled with a natural water cycle; 3. a new construction pattern coupled with a closed eco-water cycle system; which provide a new concept for improving the scientific management of the urban aquatic ecosystem.
