The results show that: 观特征和外部空间形态两个方面研究了公 (1) park area, width and landscape shape index (LSI) are the main factors which obviously 园的降温效应。研究结果表明：在公园内部 influence the cooling effect of urban park, and small area parks have better cooling effect 景观要素方面，公园面积、宽度、形状指数 than a large urban park with the same area as the total area of small parks. (2) Terrain and 是影响公园降温效应的主要因素，多个小型 building space form also have a great impact on urban park cooling effect, ventilation corridor 公园比同面积大型公园具有更好的降温效 and geometry building layout can effectively promote the cooling effect of urban park, and 应；在公园外部空间形态方面，自然地形起 mountain park has a better cooling effect than basin. In order to make the best cooling effect of 伏与建筑空间形态是影响公园降温效应的 urban park, area, layout and their combination should be considered comprehensively in urban 主要因素，少量正对公园的通风廊道及规 planning. 则布局的建筑形态可以有效提升公园的降 Keywords: Urban Park; Urban Heat Island; Cooling Effect; Mountain City; Park Form 温范围，山地型公园比盆地型公园具有更好 的降温效应。在规划实践中，应该综合考虑 公园面积
