摘要： 利用塔里木河上、中、下游采集的胡杨年轮数据和1957—2010年的径流资料，分析塔里木河干流地区胡杨径向生长量与径流量的对应关系。结果表明：① 塔里木河上、中游4个断面的胡杨径向生长量存在显著变化，在20世纪80—90年代出现峰值，总体呈下降趋势。下游2个断面胡杨径向生长量在2000年前年际变化较小，2000年后，受生态输水影响胡杨径向生长量变化幅度较大，英苏和依干不及麻断面分别在2003年和2006年出现峰值。② 塔里木河肖夹克、新渠满、沙子河口、阿其克、英苏和依干不及麻断面的胡杨径向生长量突变分别发生在1996、1999、1991、2000、1998年和1960年或1968年或1978年。③ 塔里木河上、中游胡杨径向生长量与当年1—2月的径流量正相关性最高，下游胡杨径向生长量与当年1—2月的径流量负相关性最高。

Abstract: The data of treering of [WTBX]Populus euphratica[WTBZ] and monthly and annual runoff volumes of the Tarim River in Xinjiang during the period from 1957 to 2010 were analyzed using the methods of dendrohydrology and correlation analysis. The results are as follows: ① The radial growth of [WTBX]P.euphratica[WTBZ] changed significantly along the 4 profiles in the upper and middle reaches of the Tarim River. A peak value occurred during the period from the 1980s to the 1990s, and then it was in a gradual decrease trend. The change of annual radial growth of [WTBX]P.euphratica[WTBZ] along two profiles in the lower reaches of the Tarim River was not obvious before 2000, but the annual radial growth began to sharply increase after 2000; ② The MannKendall mutation analysis was used to analyze the change of radial growth of [WTBX]P.euphratica[WTBZ] along 6 profiles. The result showed that the mutation of radial growth of [WTBX]P.euphratica[WTBZ] along the profiles of Xoxak, Xinquman, Shazihekou, Archik, Yengisu and Yiganbjima occurred in 1996, 1999, 1991, 2000, 1998 and 1960 or 1968 or 1978 respectively; ③ There was a high correlation between the radial growth of [WTBX]P.euphratica[WTBZ] and the runoff volume in the upper and middle reaches of the Tarim River in January and February, but a high negative correlation between the radial growth of [WTBX]P.euphratica[WTBZ] and the runoff volume in the lower reaches.
