中文摘要：

夏代至清代约4000a的历史时期，中国热带西部的气候波动比热带东部微弱。东部的5个冷期之中，周、战国至西汉、晋、唐末至南宋冷期，在西部仅有个别冷波动的实例，反而可以举出较多的暖波动现象。明清小冰期东、西部基本同步。东部的3个暖期（汉、唐、元明）在西部也有相应的表现。中国热带历史时期的冷波动与太阳活动的平静期有一定的相关。热带东、西部气候波动的差异，主要是由于东部受东亚季风的影响，而西部则受南亚季风的影响。

英文摘要：

During the historical period of about 4,000 years from the Xia Dynasty to the Qing Dynasty, the climate fluctuation in the west part of tropical China was weaker than that in the east part. Five cooling stages occurred in the east part , namely the Zhou Dynasty, the Warring States-Western Han Dynasties, the Jin Dynasty, the late Tang-Southern Song Dynasties and the Ming-Qing Dynasties, among which the Little Ice Age of the Ming-Qing Dynasties was synchronous essentially in the two parts, but for the former four cooling stages in the west part, only one or two cooling events can be recognized, on the contrary some samples of warming fluctuations can be enumerated. The three warming stages in the east part, during the Dynasties of Han, Tang and Yuan-Ming, appeared similarly also in the west part. The cooling fluctuations in China＇s tropics during historical period were related to the tranquil stages of solar activity. The difference of climate fluctuations between the east part and west part of tropical China is a result of different monsoon influence： the east part of tropical China is influenced by East Asian monsoon while the west part by South Asian monsoon.
