【摘要】 为分析渤海湾沿岸不同规模城市在城市化进程中区域人体舒适度的时空变化特征,研究按行政级别选出三个规模级别城市:直辖市(天津);地级市(唐山、沧州、东营);县级市(县)(霸州、黄骅、乐亭、饶阳及惠民)。依据各城市1980-2013年间气温、相对湿度及风速的月平均值,计算出各城市1980-2013年间各月份人体舒适度指数(HCI)。结果表明:渤海湾沿岸4月~6月上旬及8月上旬~10月上旬为区域城市人体感觉舒适时段。为分析不同规模城市人体舒适度在冷、热季的差异,以人体舒适区(51≤HCI≤75)为界将年内其余时段分为冷季和热季,结果显示:不同规模城市间人体舒适度的差异在冷季差异较大,热季差异较小;冷季,1980-1996年间海陆差异明显,1997-2013年间却呈现出明显的斑块状;热季,人体舒适度空间分布格局在前后两个时段无明显变化,均表现为海陆梯度渐变特征。更多还原

【Abstract】 In order to explore the temporal and spatial variation of the human comfort under the urbanization process in different size cities along the Bohai Bay coastal area,cities named Tianjin(Municipalities),Tangshan,Cangzhou,Dongying(prefecture-level),Bazhou,Huanghua,Laoting,Raoyang,Huimin(countylevel)were selected according to the administrative level.Human Comfort Index(HCI)was calculated based on monthly average of air temperature,relative humidity and wind speed during 1980-2013.According to the HCI,April-early June and early August-early October are the most comfortable period along the Bohai Bay coastal area.Set the most comfortable zone(51≤HCI≤75)as a dividing line,the other periods were divided into Hot Index(HI)and Cold Index(CI).The results show that the difference gap of human comfort in different scales cities is different,a large in cold season,small in hot season.The spatial changes pattern of human comfort in hot and cold seasons are quite different:In cold season,there appeared an obvious differences between land and sea from 1980 to 1996,whereas an obvious localization from 1997 to 2013;In hot seasns,the spatial distribution pattern changed little,both showed a significant land and sea gradient at two stages.更多还原
