| 摘 要： | 根据联合国防治荒漠化公约的有关规定，运用Ｔｈｏｒｎｔｈｗａｉｔｅ计算可能蒸散量的方法作出了第一张中国荒漠化气候类型分布图，首次确定了中国荒漠化的潜在发生范围。结果表明，中国荒漠化潜在发生范围约３３１７０３２．２ｋｍ２，占国土面积的３４．６％，分布于全国１８个省（自治区，直辖市），４７０个县（市、旗）。其中亚湿润干旱区总面积为７５１１６１．９ｋｍ２，占国土面积的７．８％；半干旱区总面积为１１３９２１４．２ｋｍ２，占国土面积的１１．９％；干旱区总面积为１４２６６５６．１ｋｍ２，占国土面积的１４．９％。

| Abstract: | The first climatic type distribution map of desertification in China has been drawn out making use of Thornthwaite method which was recommended in International Convention to Combat Desertification. On the map, the potential extent of desertification in China has been outlined. The results show that among the 3 317 032 2 km 2 potential areas, there are 751 161 9 km 2 distributed in semi humid prone to aird area, 1 139 214.2 km 2 distributed in semi arid area and 142 665 1 km 2 in arid area, and their proportions to territory are 7.8%, 11.9% and 14.9% in order. The potential extent of desertification in China cover administrative divisions of 18 provinces and 470 counties and consists of 34.6% of the territory. |
