| 摘 要： | 利用深圳多个区域自动气象站资料,采用考虑了气温、风速、相对湿度等要素的人体舒适度计算方案，计算了深圳地区的人体舒适度指数以及不同舒适等级天数，分析了城市地形地貌、路网密度和人口密度等因素对人体舒适度的影响。结果表明：深圳地区沿海比内陆舒适，全市全年舒适天数为7-9个月，夏季感觉热的天数约为2-3个月，冬季感觉冷的天数大部分地区为30 d左右。从不同地区人体舒适度指数的日变化特征来看，夏季比冬季更易受地理位置和下垫面等因素影响。地形地貌、海陆分布、城市规划等地理因素对人体舒适度均有一定影响，相关分析表明海拔高度、道路占地面积和人口密度与热-炎热日数呈对数关系。但在深圳的东部人口稀疏和道路占地较小地区也并非舒适宜人，也会出现较多炎热天气，这与该地区年平均风速相对微弱有直接关系。

| Abstract: | According to the temperature, wind speed,relative humidity data from several regional automatic meteor- ological stations in Shenzhen, the human comfort index and the days on different comfort levels were calculated by a human comfort index scheme, and the influences of urban landform, road network density and population density on human comfort were analyzed. The results show that the people feel more comfortable in the coastal area than in the inland of Shenzhen. The annual comfortable days are about 7-9 months in Shenzhen. The hot days are about 2- 3 months in summer, while that of cold days are about 30 days in most areas in winter. According to the variation of daily human comfort index, the effect of geographical location and underlying surface on the index is significant in summer than in winter. Besides the above elements, topography, sea land distribution and urban planning could also impact the human comfort. The summer heat-hot days are in a logarithmic relation with elevation, road cover area and population density by a correlation analysis method. However,it is not comfortable in the eastern Shenz- hen where hot days frequent because of low population density and small road cover areas, which is relate to the weak annual mean wind speed in this region. |
