摘要:提升城市公共游憩空间的微气候舒适度对于刺激城市居民户外活动,提高城市活力尤为重要,特别是在湿热气候区城市的夏季。本文以湿热气候区的典型城市成都市的公共游憩区百花潭公园为例,选取景观的物质形体要素:水体、植物、建筑,通过实测夏季温度、风速、湿度、太阳辐射照度,量化分析景观要素对微气候舒适度的影响。结果表明:湿热地区城市露天开放空间夏季改善微气候舒适度的关键是通风和遮阴,而顺应风向的水体景观对改善城市微气候舒适度效果最明显。研究结果为湿热气候区城市露天开放性空间景观规划提供初步的研究思路和设计策略。
It is very important to stimulate outdoor activities of and arouse vitality of city through improving microclimate comfort of public recreation space, especially for the summer of city in hot and humid area. Taking the Baihuatan Park, which is a free park of Chengdu in humid and hot area, as empirical study, the paper discusses quantitatively the effect of the landscape elements (architecture, water and plant, etc.) acting on the microclimate comfort in summer. The results reflect that in summer city of hot and humid area, ventilation and shading are keys to ameliorate microclimate discomfort, and the water landscape adapting to wind has most significant effect to improve microclimatic comfort, which provides research ideas and design strategies for landscape planning of city open space in hot and humid area.
