| 摘 要： | 为使我国气候区划标准与国际气侯区划标准接轨，从其定义出发，将《国际防治荒漠化公约》中采用湿润指数划分气候区与我国传统的干燥反气候区划作比较认为：湿润指数气候区划与干燥度气候区划在理论上有相关性，其相关系数为：当≥４时，湿润指数为０．８／Ｋ，当４＞Ｋ≥１．５时，湿润指数为０．７５／Ｋ，当Ｋ＜１．５时，湿润指数为０．６５／Ｋ．在实际应用中，湿润指数气候区划与干燥度气侯区划相比较，我国湿润区面积有所扩大，极干旱气候区域有所北移。

| Abstract: | The climatic division depended on humidity index used in "the UN convention to Combat Desertification" is very different from that depended on traditional aridity of China. Starting from their definitions, a comparison about the two division methods has been made and thus found out the relations and differences between them. In addition, a peliminary method has been put forward to approach niternational criterion by using previous climatiC data. |
