| 摘 要： | 根据湖泊、山地冰川、黄土与古土壤序列、泥炭及沙漠演变等多种地质记录的综合对比分析，重建和恢复了我国酉部地区全新世以来的自然环境演变序列及特征。全新世期间我国西部地区环境演变存在着以水热配置关系不同为突出特征的两种不同的演变模式：即以新疆北部地区为代表的西风型和以青海湖及青藏高原为代表的季风型模式。其成因同区域性特征及大气环流形势密切相关。并划分出我国西部地区全新世自然环境演变过程中的几个重要时间界线，即距今１２ｋａ或１０ｋａ、９ｋａ、３ｋａ和０．５ｋａ。众多地质记录间良好的对比关系对于深入理解我国西部全新世气候环境的演变过程，预测其变化趋向具有十分重要的意义。

| Abstract: | By comprehensive recording and correlation of lakes, land and glacier, loess and paleo-soil series, peat and desert, the .evolution series and characteristics of Holocene natural environment are reconstructed. Two models characterized by different water-heat allocation occured during Holocene in the wester China, that is, westward wind type represented by northern Xinjiang area, and monsoon type represented by Qinghai lake and Qinhai-Tibet plateau, genetically related with regional characteristics and air circulation.Several importment time boundary were subdivided, that is, 12 ,000 aBP or 10, 000 aBP, 9, 000 aBP, 3, 000mp and 500 aBP. A good correlation of different geological records has an important significance on understanding the evolution of Holocene natural environment and predicting the evolution trend. |
