摘　　要：Daily temperature data from 599 stations across China for the years 1961 to 2007 were used to analyze the changes in the natural regional boundaries. The results show that the accumulated temperature ≥10℃ and its duration changed dramatically from the end of 1990s to the early 21 st century. The amplitude of natural regional boundaries was greater in the 21st century than it was in the 20th century. In the eastern region of China, the climatic zones were migrating generally northward, with the northern edge of the subtropical zone and the eastern section of the warm temperate zone showing an obvious northward shift of up to 1-3° of latitude. The climatic zones moved south in the Qinghal-Tibet Plateau, western Inner Mongolia, and some areas of western Xinjiang, and slightly to the north in other parts of the western region.Daily temperature data from 599 stations across China for the years 1961 to 2007 were used to analyze the changes in the natural regional boundaries.The results show that the accumulated temperature ≥ 10℃ and its duration changed dramatically from the end of 1990s to the early 21st century.The amplitude of natu-ral regional boundaries was greater in the 21st century than it was in the 20th century.In the eastern region of China,the climatic zones were migrating generally northward,with the northern edge of the subtropical zone and the eastern section of the warm temperate zone showing an obvious northward shift of up to 1 3° of lati-tude.The climatic zones moved south in the Qing-hai-Tibet Plateau,western Inner Mongolia,and some ar-eas of western Xinjiang,and slightly to the north in other parts of the western region.
