| 摘 要： | 本文回顾和综述了20世纪中期以来我国在干湿气候区划指标、潜在蒸散计算方法、干湿气候区划等级划分标准及命名方式等方面的研究进展，在此基础上给出了利用干燥度指数进行干湿气候区划的计算方法和等级划分标准，并利用1981-2010年全国2207站的气象观测资料，对近30年来我国干湿气候空间特征进行了分析。结果表明，最近30年我国干旱区（包括极干旱、干旱和亚干旱区）面积为469.2万km2，占国土面积的48.8%，其中极干旱区、干旱区和亚干旱区面积分别为87.8万km2、209.2万km2和172.2万km2，分别占国土面积的9.1%、21.8%和17.9%，主要分布于新疆、内蒙古、西藏、青海、甘肃等西部地区；亚湿润区、湿润区和极湿润区面积占我国国土面积的比例分别为16.2%、27.8%和8.8%，主要位于我国长江以南及东北部分地区。

| Abstract: | The dry-wet climate regionalization index, potential evapotranspiration calculation methods, standard and named method of the dry-wet climate regionalization, etc., are reviewed in this paper since the middle of the 20th century. Using the arid index, climate regionalization and class standard were given on the basis of former review. Then, the characteristics of dry-wet climate division were analyzed using observed data at 2207 national meteorological stations from 1981 to 2010. The results showed that arid area (including the extreme arid, arid and semi-arid areas) was 4.692 million hm2 in China, accounting for 48.8% of the land area in China, which included 0.878 million hm2 (9.1%), 2.092 million hm2 (21.8%) and 1.722 million hm2 (17.9%) for extreme arid, arid and semi-arid area respectively. The arid areas were mainly distributed in Xinjiang, Inner Mongolia, Tibet, Qinghai, Gansu province and other western regions. The sub-humid area, wet area and excessive wet area accounted for 16.2%, 27.8% and 8.8% of China’s land area respectively, mainly located in the south of the Yangtze River and Northeast China. |
