中文摘要	通过研究塔克拉玛干沙漠南缘地区安迪尔故城、安迪尔牧场和达玛沟乡3个不同地点的红柳沙包沉积纹层,系统分析了近400多年来红柳沙包落叶阳离子与气候环境变化的关系。结果表明,3个采样点中4种阳离子的变化幅度排序均为Ca~(2+)> K~+> Mg~(2+)> Na~+,其中Ca~(2+)含量的变化与阳离子总量变化的相关系数最高,表明可以用Ca~(2+)含量的变化或阳离子总量的变化分析气候环境变化趋势。红柳沙包落叶阳离子含量与温度呈负相关,依此划分塔南地区近400多年来的冷暖期,15901691年为暖期,16921896年为冷期(其中暖波动为17991808年、18251829年、18781881年和18871891年),18972010年为暖期(其中冷波动为19391941年、19921998年);降水量与红柳落叶阳离子含量的相关性较差;阳离子含量变化与区域洪水事件有较好对应。进一步完善了利用红柳沙包阳离子含量变化揭示气候环境变化的可行性,填补了塔南地区近400多年来高分辨率气候变化部分时段的空白。
英文摘要	Based on the research on Tamarix cone sedimentary veins in three different places which are Andier Ancient City,Andier Meadow,and Damagou Township in the southern region of the Taklimakan Desert,the relationship between the characteristics of the positive ion content in Tamarix fallen leaves and climatic change during the past 400 years is systematically analyzed. The results show: the order of four kinds of positive ion content s change range in three sampling sites is Ca~(2+)> K~+> Mg~(2+)> Na~+. The correlation coefficient between Ca~(2+) content and the total positive ion content is higher, which indicates that Ca~(2+) content or the total positive ion content can reflect the change trends. There is an inverse correlation between positive ion content in Tamarix fallen leaves and the local temperature. According to the change of positive ion content, the climate in the southern region of the Taklimakan Desert can be divided into cold and warm periods during the past 400 years, among which the period of 1590-1691 is warm period, of 1692-1896 is cold period (warm fluctuations are 1799-1808,1825-1829,1878-1881,1887-1891), of 1897-2010 is warm period (cold fluctuations are 1939-1941,1992-1998) ; Precipitation has a poor correlation with the positive ion content ; There is a better correspondence between the changes of positive ion content and the regional flood events. This research provides a kind of research method for the environmental evolution in the southern region of the Taklimakan Desert,and it is of great help to environmental change research of the arid desert regions. It has further perfected the feasibility of using positive ion content in Tamarix cone sedimentary veins to reveal the environmental change,and fills up the blank of high resolution climatic change during the past 400 years in the southern region of the Taklimakan Desert.
