城市水域是人类赖以生存的重要生命支持系统之一,城市水域生态系统的调控机理对维护城市水资源及环境的健康、持续、稳定发展具有重要意义。论文从城市水域问题的生态学实质出发,基于五律协同原理,研究城市水域生态系统的调控机理及模型。研究表明,城市水域生态系统的"六位一体"调控具有时空层次性、综合性、阶段性特征,灰色评估模型可定量评估城市水域生态系统的健康、持续程度,随着城市水域生态系统的结构和功能不断完善,其六位一体度亦随之增高。选取我国著名水域北京颐和园昆明湖、杭州西湖、南京玄武湖、济南大明湖进行案例比较研究,为我国城市水域生态建设提供借鉴和参考。
Urban water is one of the important life-support systems to human beings.The regulation mechanism of urban water ecosystem is of great significance in maintaining the sustainable development of urban water resources and environment.Based on the synergism of five rules,discussions were carried out in this study to explore the regulation mechanism and model of urban water ecosystem.The results indicate that,the urban water "Six in One" principle possesses temporal and spatial,comprehensive and phrasal features.Gray evaluation model can quantitatively evaluate the health and sustainable degree of urban water ecosystem.The Six in One degree is positively proportional to the continuous improvement of urban water ecosystem structure and function.Finally,the comparative studies of some typical cases including Beijing Kunming Lake of Summer Palace,West Lake in Hangzhou,Nanjing Xuanwu Lake and Ji'nan Daming Lake were carried out to analyze the motivation of becoming well-known waters and then to provide references to urban water ecosystem construction.
