利用保定市12个气象站1971—2010年的气象数据以及人体舒适度指数(DI)公式计算了该地区不同地貌环境下的人体舒适度指数。结果表明,保定市体感较舒适的月份出现在4、5、6、8、9月,山区部分在7月仍维持着偏暖较舒适的状态,平原地区和湿地地区在10月仍然维持较舒适的状态;该地区的冷不舒适天数呈波动减少趋势,变化明显;舒适天数呈波动减少趋势,变化不明显;热不舒适天数呈显著增加的趋势,变化明显;该地区的舒适度指数存在周期性变化,以16年的周期最为明显;该地区冷不舒适的天数由西北部向东南递减。舒适出现天数西部山区和东北部较多,热不舒适出现天数由西北向东南递增。
Based on the meteorological data from 1971 to 2010 of 12 meteorological stations in Baoding city and the body comfort index(DI)formula,the body comfort index of different landforms in the area was calculated.The results showed that:The time which was more comfortable appeared in April,May,June,August and September in Baoding city.The mountain area maintained comfortable state in July,and the plain and the wetland remained relatively comfortable in October.The trend of change about cold discomfort days was reduced significantly.The trend of change about comfortable days was decreased too,but the change rate was not obvious.The trend of change about heat discomfort was increased significantly,and the change rate was obvious.The body comfort index of this area had some periodic changes,and the most obvious of the cycle was 16-year.The days of cold discomfort were decreased from northwest to the southeast.The days of comfort were more longer in the western and the northeast than the others in Baoding city,the days of thermal discomfort were increased from northwest to southeast in Baoding city.
