摘要
将混沌论引入城市绿地空间研究领域,进行空间布局多情景优化的空间模拟引导,有助于将复杂系统的不可预测性、随机性和科学的规律性、确定性优化框架相协调,为城市绿地系统的演化及优化提供新的思维视角。文章在阐明混沌论的理论内涵和研究进展基础上,分析作为一个混沌体系的绿地系统演化特点,探讨基于不确定性的情景规划策略,并以上海崇明世界级生态岛为研究案例,以情景规划为研究方法,进行3项目标导向下的绿地系统布局的多情景优化模拟,即生态导向、游憩导向、协调导向。研究结果发现,协调导向性布局尽管在单个属性上均未达到最优,但却是综合效能最大化的情景方案,也是崇明岛达到"自然生态"和"生态发展"双维度"世界级生态岛"创新发展的空间建设要求所在。
The chaos theory is introduced into the study of urban green space to conduct the spatial simulation guidance for multi-scenario optimization of spatial layout, which helps to coordinate the unpredictability and randomness of complex systems with the scientific regularity and deterministic optimization framework,and provides a new perspective for the evolution and optimization of the urban green space system provides a new perspective. On the basis of clarifying the theoretical connotation and research progress of the chaos theory,the paper analyses the evolution characteristics of green space as a chaotic system,explores the scenario planning strategy based on uncertainty,and takes Chongming world-class ecological island in Shanghai as a case for the multi-scenario optimization simulation of green space system layout under 3 scenarios orientation: ecological orientation,recreation orientation and coordination orientation. The result shows that although the coordination-oriented layout is not optimal in terms of individual attributes,it is the scheme with maximum comprehensive efficiency. This is also the space construction requirement for Chongming Island to achieve the innovative development of "world-class ecological island"in the two-dimension of "natural ecology"and "ecological development".
