| 摘 要： | 利用2014年采自巴丹吉林沙漠西南缘的胡杨样本,建立了该地区胡杨树轮年表,选用相关函数法结合高台气象站历年逐月降水和温度(月平均气温、月平均最高气温、月平均最低气温、平均地温)等主要气候因子,分析巴丹吉林沙漠西南缘胡杨树轮对气候的响应；研究表明,黑泉乡胡杨树轮宽度标准化年表与生长季平均气温相关较好,具有明显的正相关关系。而生长季3-9月的平均气温与胡杨树轮宽度年表的相关高达0.629(P<0.0001),3-9月的平均气温可能是该地区胡杨树木径向生长的主要限制性因子且具有明确的树木生理学意义。

| Abstract: | In this study, we developed a tree-ring width chronology using the Populus euphratica tree-ring samples. The samples were collected from the Southwest Edge of Badain Jaran Desert in 2014.The tree-ring width chronology response to climate was analyzed using monthly precipitation, average maximum temperature, mean minimum temperature and average temperature from Gaotai meteorological station. Response function analysis shown that the temperature of Growing season is limiting factor for tree radial growth, there have a best correlation between tree-ring width chronology and temperature in June (r=0.512, p<0.0001), while the average temperature from March to September is a major limiting factor. |
