中文摘要	红柳沙包是干旱区发育的一种生物地貌类型.罗布泊地区的红柳沙包主要分布在塔里木河、孔雀河、米兰河等三角洲地带.通过研究发现其中有些沙包具有清晰的"年层"构造,与树木年轮一样,具有计年和储存环境信息的功能,可以用来探讨和恢复过去气候和环境变化.但由于红柳生长发育规律和研究区环境的复杂性,利用红柳沙包年层在研究环境演变,在理论和实践上都有待进一步完善和提高.
英文摘要	Tamarix ramosissima sand-hillocks are a kind of biological landforms. Tamarix ramosissima sand-hillocks in the Lop Nur Lake region of southern Xinjiang are mainly distributed in the deltas of the Tarim River, Kongque River, Miran River, etc. Some of them have the clear "annual stratum" structure and the function of dating and storing environmental information as tree rings. In this paper, the changes of 513C values and C/N values of leaves of Tamarix ramosissima and the sand stratum thicknesses in Tamarix ramosissima sand-hillocks on the right riverside of the Miran River are analyzed, and the climate change since recent 132 years is divided into 3 stages: (1) During the period of 1871-1926, the climate was cold, arid and windy, and sand drift disasters occurred frequently; (2) During the period of 1927-1966, the climate was relatively cold and arid, and it fluctuated significantly; (3) During the period of 1967-2002, the climate was warmer, and the precipitation was slightly increased. These results accord basically with the meteorological records. It is the first to approach and get back the climate and environmental change in the past by using the annual strata of Tamarix ramosissima sand-hillocks.
