    摘要:城市公园空间视觉吸引机制模式研究是指导城市公园规划设计与管理的重要依据。以美国西雅图奥林匹克雕塑公园为研究对象,对城市公园空间视觉吸引要素进行调查,运用统计学的主成分分析法将视觉吸引要素进行有效性分析、相关性分析和因子分析,甄别出城市公园空间视觉吸引的7类要素,并以此为基础,采用直接观察法和访谈调查法解析城市公园空间视觉吸引机制的运行原理。同时对视觉吸引要素特征进行重组、加工和编评,形成综合显著图,共同构建城市公园空间视觉吸引机制工作模式。该成果为城市公园规划设计和视觉资源管理评价研究奠定了理论基础。

    Abstract:Study on the mechanism mode of visual attraction in urban park space is an important basis of guiding the planning and management of urban park. By taking Seattle Olympic Sculpture Park as the research object, this thesis does surveys on the elements of visual attraction in urban parks and uses principal component analysis to do effective, relevant and factor analysis for visual attraction, in order to screen for seven categories of attractive elements in the interest of analyzing principal visual attraction mechanism of urban park space through direct observation and interview survey. Moreover, the characteristics of visual attraction elements are recombined, processed and evaluated to form a comprehensive saliency map, thus working together to build vision attraction mechanisms mode in urban parks. The research findings are the theoretical basis of the urban park planning and research on the evaluation of visual resource management.
