新疆干旱区晚更新世以来的温湿对应关系的探讨

AN APPROACH TO THE CORRELATION BETWEEN TEMPERATURE AND HUMIDITY IN XINJIANG

本文基于将今论古的历史比较法,根据多方面资料分析,论证了新疆在独特的地理环境下,冷湿和暖干的对应是晚更新世以来气候变迁的一般规律。文中探讨了大气环流的影响,认为季风气候是形成我国东部地区暖湿和冷干相结合的主要因素。典型的大陆性气候使新疆的温湿组合状况与东部地区相反。东西两种状况的交界带应是季风气候影响范围的界限。

It is a common knowledge that the combinations of dry with cold andwarm with wet under the domination of the monsoon are typical climatepattern in the eastern China. But the cold glacial epoches were not extr-emely dry and the warm interglacial epoches were not humid in the specialgeographical environment of Xinjiang since the late Pleistocene. Based onthe observation records and statistical data in Xinjiang, The author provedthe correspondence of cold-wet and hot-dry is a general climate pattern inthe special arid region of Xinjiang. Discussing the influence of the atmos-pheric circulation, the author pointed out that the monsoon is the mainfactor in forming the combination of warm-wet and cold-dry in the easternChina. with the typical continental climate, Xinjiang has the contrarycombination of temperature and humidity since the late Pleistocene. Theboundary of two different situations should be the limit of the influencefrom monsoon.
