城市开放空间体系是城市复合空间系统中最主要的子系统之一，剖析其在景观触媒效应影响下的构建机制将成为提升城市魅力和品位的重要抓手。针对景观视角下山地城市开放空间系统性研究匮乏的现状，本课题运用整合性跨学科研究方法，依据山地城市具有山水格局独特、人文气质迥异、空间资源紧缺、生态环境脆弱的显著特征，借助GIS技术建立开放空间环境特征参数化分析模型，并结合公众参与途径，解析山地城市开放空间触媒效应受制的成因；借鉴多元系统分析方法，确立山地城市开放空间的研究程序和全过程评价系统，用以探寻具有景观触媒效应的开放空间体系的建设策略；经由样本城市片区建设实证反馈完善，揭示构建景观触媒效应下的山地城市开放空间体系的科学途径；进而实现辨识开放空间体系构建机制和城市综合空间品质提升之间的耦合关系，并解决因缺乏量化评价而导致开放空间研究难以深化的瓶颈问题。成果将丰富风景园林视野下山地城市规划设计研究的理论与方法。

Open space system is one of the most important subsystems in city’s compound system. For shaping the urban charm and taste, it’s critical to dissect the building mechanism of open space system based on landscape catalysts effects. In consideration of lacking systematic research of open space system in mountain city which shared with unique characteristic landscape pattern, humanistic temperament, space shortage, and fragile ecosystem, this research will apply the way of integrate and interdisciplinary study to reveal the reason of landscape catalysts effects not doing well by means of GIS technology and parameterized descriptive modelling and the way of public participation. With the help of multi-system analysis method to build up the full process for establishment system of open space with the effects of landscape catalysts, the developing strategies for the open space will be determined. Through the urban design practice in sample urban fabric, the scientific approach and methodology for the system’s organization of open space will be concluded. Furthermore, it can be identified that the coupled relationship has been established between the promotion for comprehensive quality of urban space and mechanism of open space system. At meantime, the bottleneck problem can also be solved, which cause the research of open space couldn’t be carried out successfully because of be short of quantitative evaluations. This achievement will enrich urban design theory and method in the view of landscape architecture.
