Environmental changes and lake level fluctuation recorded by lakes on the plain in northern Xinjiang during the late Holocene

Xinjiang 自治区域位于干旱区域在那里的 Chinaand 西是关于过去的温度和潮湿的变化的许多争论。大多数在北 Xinjiang 的平原上的湖是封上的湖和终端湖。他们能显然在 palaeoclimate 反映变化。在 northernXinjiang 的一些平凡的湖的 palaeoenvironmental 变化将从西昌·莱克， DongdaohaiziLake 和艾比·莱克主要基于花粉，沉积外形，点火(LOI ) 上的损失，危险性和谷物尺寸的数据在迟了的 Holocene 期间被分析。结果揭示温度和 bycold 湿、温暖干燥的统治的潮湿的一个装配模式。另外，影响因素将被讨论。

Xinjiang Autonomous Region is located in the arid area of westerly of China and there are many arguments about the changes of past temperature and moisture. Most of the lakes on the plain in northern Xinjiang are sealed lakes and terminal lakes. They can evidently reflect the changes in palaeoclimate. The palaeoenvironmental changes of some plain lakes in northern Xinjiang during the late Holocene will be analysed mainly based on the data of pollen, sedimentary facies, loss on ignition （LOI）, susceptibility and grain size from the Sichang Lake, Dongdaohaizi Lake and Aibi Lake. Results reveal an assembled pattern of temperature and moisture dominated by cold-wet and warm-dry. In addition, the impact factor will be discussed.
