中国人皮肤相对湿度的地理分布

根据Ｂｅｒｇｌｕｎｄ等人（１９８３）公式：Ｗ＝（ｅｓｋ－ｅａ）／（ｅｓｓｋ－ｅａ），利用大气温度，大气水汽压和皮肤温度的月平均值，计算皮肤相对湿度，并按皮肤相对湿度划分舒适带。结果表明，决定我国皮肤相对湿度地理分布的基本因素是纬度，海陆分布，地形和大气环流，季节不同，则各因素所起作用有差异。作者以皮肤相对湿度２５％－４５％表示舒适带，计算表明，我国气候舒适带有明显的地区差异和季节变化。

Geographical Distribution of Relative Humidity of Chinese Skin

According to Berglund's formula (1983 ): W =(esk-ea)/essk-ea), the relative humidity of man's skin is calculated by means of the monthly mean value of air temperature,vapour pressue and skin temperature. The climate comfort belts are divided according to the relative humidity of the skin. It showed that the main factors which decided the distribution of the relative humidity of Chinese skin are latitude,distribution of sea-land, topography and atmospheric circulation. China's climate comfort belt is defined according to the relative humidity of the skin 25% - 45%.There are obvious regional difference and seasonal variance in the China's climate comfort belt.
