The layers of Tamarix cones within sedimentary deposits in arid regions have significant chronological and paleoenvironmental implications. Here, we compare the δ¹⁸O values of Tamarix cones in the Hongliujing area of Lop Nur with meteorological data for the Ruoqiang meteorological station for 1960–2019 AD. Linear regression analysis was used to reconstruct the average temperature for April and the precipitation for November in the Hongliujing area over the past 200 years. The results showed that the δ¹⁸O values were significantly negatively correlated with the temperature for February, April, May, August, December, and with the annual mean temperature; significantly negatively correlated with the precipitation for February and April; significantly negatively correlated with the sunshine hours for March and May; significantly positively correlated with the sunshine hours for February, July, August, October, and December, and with the annual mean values; and significantly correlated with the relative humidity for April, July, August, September, October, and November, and with the annual mean values. Based on the δ¹⁸O record of the past 200 years, the Hongliujing area experienced two warm-wet periods (1874–1932 and 2004–2019 AD) and two cold-dry periods (1832–1873 and 1933–2003 AD). Thus, the climate was characterized by alternating warm-wet and cold-dry conditions. Wavelet analysis revealed three main cycles: 45 years, 29 years, and 14 years.

干旱地区沉积物中的柽柳锥层具有重要的年代学和古环境意义。这里，我们将罗布泊红柳井地区柽柳球果的δ ¹⁸ O值与若羌气象站1960-2019年的气象数据进行了比较。利用线性回归分析重建了红柳井地区近200年4月平均气温和11月降水量。结果表明，δ ¹⁸ O值与2月、4月、5月、8月、12月气温及年平均气温呈显着负相关；与2月、4月降水量显着负相关；与3月、5月日照时数显着负相关；2月、7月、8月、10月、12月日照时数及年均值呈显着正相关；与4月、7月、8月、9月、10月和11月的相对湿度以及年平均值显着相关。根据过去200年的δ ¹⁸ O记录，红柳井地区经历了两个暖湿期（公元1874-1932年和2004-2019年）和两个冷干期（公元1832-1873年和1933-2003年）。因此，气候的特点是暖湿和冷干交替。小波分析揭示了三个主要周期：45 年、29 年和 14 年。
