Abstract: Environmental Evolution of Holocene Epoch in several areas of Xinjiang passed through three evolutional processes,namely dry cool weather in early stage,warm humid weather in middle stage and dry cold weather in late stage,but each stage had little climatic fluctuations of different time-scales.The climatic vicissitudes of Xinjiang basically accorded with the global weather fluctuation regularities,but they had evident regional characteristics.The modern tectonic movement of Early Holocene Epoch profoundly affected the physical evironmental vicissitudes of Xinjiang, The mid-Holocene was characterized by warm-humid weather,while the late Holocene was the rapid developmental period of arid land,being the most important period in the Holocene development history of whole Xin Jiang, studies on various depositional phases of different periods in several plains,foothills and mountainous areas of Xinjiang showed that the whole Holocence existed several dry and humid as well as glacial and interglacial stages,however the general tendency tended to become drier and drier.These results provide an important information for predicting future climate and production investments.
