Abstract：The district of Lop Nur in Xinjiang is one of the most important cradlelands of Chinese culture. In Han and Tang Dynasty, it was the passage-way from China to west Asia and Europe, which was so called the famous “The Silk Road”. It gestated the Loulan culture for more than 1000 years. But because of the effection of geologic tectogenesis and the human activity, the district of Lop Nur turned to be a place of many basified lakes and valstitude deserts.How did this process occurred？Is there any climatic gyrations in the process and important environmental events？when and how these events occurred, what was the role of the human activity.The embedded research on these questions must provide with important academic significance.It can also provide scientific criterion for the Western China Development. The purpose for this study is to recognize the process of environmental evolution happened in the Lop Nur areas on the basis of the analysis of some well-round fruits. In addition, we bring forward to research on the precise timing of lacustrine gypsum in the profile core since the last interglacial period and high resoving environmental indexes, which will be much help for understanding the desert process in the Lop Nur.
