| Abstract: | Xinjiang, locating in central Asia, is well-know for its aridity. Qwing to the warm ing trend of the world, it is afraid of what there will be a warm-dry trend of climate in future that will be disadvantageous to economic and social development in Xinjiang. To know the future condition of climate and environment in Xinjiang is becoming an emer gence thing. To predict the climate trend, however, it must know the circumstance of past climate and environment. In past decades many studies in climate and environment changes since the Tertiary were done. Many data and information can be used to discriminate the future climate trend in Xinjiang. Therefore, this paper first reviews some present studies on past climate and environment and then discusses the possible trend of climate in Xin jiang.In reviewing the past climate and environment in Xinjiang, the whole accounted time is dassified into three different time scales, i. e., geological, historical and instrumental scale respectively and the characteristics of past climate and environment in Xinjiang are analysed, and then their possible trend is predicted.From a consideration of above mentioned aspects, it is concluded that the arid condi tion in Xinjiang is still remained since the early age of the Tertiary- However, climate and environment variations that were characterlzed by dry-damp and cold-warm alternation have taken place during this long time. Obviolasly periods of climate and environment vari ations such as looa and 1ka are found. By prediction, the arid condition in Xinjiang will be remained in the middle times of next century. The air temperature will slightly rise in win ter and decrease in summer. The precipitation will increase a little. |
