| 摘 要： | 根据采用同一区划方法、指标体系划分的1951-1980 年及1981-2010 年中国气候区划结果,对比分析了过去60 年中国气候区划的主要界线变化特征。结果表明：1951-1980 年至1981-2010 年,我国寒温带界线西缩、北移;暖温带北界东段北移,其中最大北移幅度超过1个纬度;北亚热带北界东段平均北移1 个纬度以上,并越过淮河一线;中亚热带北界中段从江汉平原南沿移至了江汉平原北部,最大移动幅度达2 个纬度;南亚热带北界西段北移0.5~2 个纬度;青藏高原亚寒带范围缩小,高原温带范围增加。东北湿润、半湿润区虽转干与趋湿并存,但其中温带地区的湿润—半湿润东界东移,大兴安岭中部与南部的半湿润—半干旱界线北扩;其他地区的干湿分界线虽未出现明显移动,但北方半干旱及华北半湿润区总体转干,河西走廊、新疆及青藏高原的干旱、半干旱区总体转湿;而南方湿润区则趋干与转湿并存。

| Abstract: | The paper analyzed the characteristics of changes on regionalization boundaries of climate over China, based on the regionalization scheme in 1951-1980 and 1981-2010, which was conducted using the identical classification methodologies, criteria system and homogeneous dataset. The results showed that the main boundaries of climate regionalization for 1981-2010 in China have been changed compared with 1951-1980. The boundaries of cold temperate zone shifted northward and shrank westward. The eastern part of northern boundary of warm temperate zone shifted to north with the maximal range over 1 latitude. The eastern part of northern boundary of northern sub-tropical zone shifted northward by over 1 latitude, and the northern sub-tropical zone extended to the north of the Huaihe River. The middle of northern boundary of central sub-tropical zone shifted from the southern edge of Jiang-Han Plain to north of the Plain with the maximal range of 2 latitudes. The western part of northern boundary of southern sub-tropical zone shifted northward by 0.5-2 latitudes. The area of plateau temperate zone enlarged and the plateau sub-frigid zone shrank on Qinghai-Tibet region. Although the aridification and humidification trends were both found in northeastern China, the eastern boundary of humid and sub-humid regions shifted to east, and the southern boundary of semi-arid and sub-humid regions located in the central part of Greater Khingan Mountains moved northward in central temperate zone. In the other zones of China, although the boundaries of humid regions did not show significant changes, the climate from wet to dry was found in the semi-arid and sub-humid regions in northern China, while the climate from dry to wet was found in the arid and semi-arid regions in Hexi Corridor, Xinjiang and Qinghai-Tibet Plateau. In humid region of southern China, the light aridification and light humidification trends were both found. |
