中文摘要	以塔里木河下游荒漠河岸胡杨林为研究对象,选择下游河道英苏、喀尔达依、阿拉干3个典型断面,分析塔里木河下游胡杨径向生长量的特点,基于离断面较近的气象站长时间序列的平均最低温和极端最低温气温数据,采用相关性分析法研究塔里木河下游胡杨径向生长量和胡杨年轮指数对平均最低温和极端最低温动态变化的响应。结果显示:1)塔里木河下游3个典型样点的胡杨径向生长量均呈现出下降的趋势。2)塔里木河下游的河流沿岸,阿拉干和喀尔达依断面胡杨径向生长变化与温度均呈现显著负相关趋势,英苏断面的胡杨径向生长量与温度呈现出正相关关系,但不显著。3)3个断面的胡杨年轮指数均呈现出下降的趋势。4)3个样点中年轮指数均与平均最低温和极端最低温呈现出负相关关系。
英文摘要	Taking the Populus euphratica forest in the lower reaches of the Tarim River as the object,three typical sections of the downstream rivers,Yingsu,Kardaiyi and Arakan,were selected to analyze the radial growth of the P.euphratica in the lower of the Tarim River,based on the weather station near the section.The average minimum temperature and extreme low temperature data of long time series were analyzed by correlation analysis method to study the radial growth of P.euphratica in the lower reaches of the Tarim River and the response of the P.euphratica index to the average minimum temperature and extreme low temperature dynamics.The results showed that the radial growth of P.euphratica in three typical samples in the lower reaches of the Tarim River showed a decreasing trend.There was a significant negative correlation between radial growth and temperature of P.euphratica along the rivers in the lower reaches of the Tarim River,and the radial growth of P.euphratica in the Yingsu section was positively correlated with temperature,despite not obvious.The annual growth index of P.euphratica in three sections showed a downward trend and the mid-wheel index of the three samples showed a negative correlation with the average minimum temperature and the extreme minimum temperature.
