Through a synthetical study on the profile of core ZKOOA in Balikun Lake with many kinds of means of synchronism, in this paper, we conclude the characteristic of climatic varia-tion pattern in arid area is that the cold-wet period alternated with the warm-dry period in different time scale to some degree, that cold-wet period corresponded respectively with the glacial age and high lake sureface, that warm-dry period with interglacial are and low lake surface The foundation and main reasons of the formation of this kind of climatic pattern are the distinctive inland arid environment situated in the middle latitude westerlies and ice melting water, So, this kind of climatic pattern has some universality in Xinjiang and arid area in the westerlies.
