中文摘要	树木年轮是全球变化研究中获取过去气候环境演变数据的重要载体,具有定年准确、连续性好、分辨率及重建精度高等优势。通过单调趋势检验塔里木河上中游径流量与胡杨年轮的趋势变化情况,将树木年轮与历史文献记载相结合,分析塔里木河下游树木年轮对水分供给的响应情况,印证胡杨年轮对河道改道事件响应的准确性。结果表明: (1) 19572010年,塔里木河上中游胡杨径向生长量在时间序列上逐渐下降,与径流有着相同的变化趋势,且下降趋势显著; (2)下游年轮标本显示19132000年胡杨径向生长量整体下降, 19732001年更加明显而达到近100年最低水平,拉依河的形成、改道、重归故道等与历史文献记载相同; (3)生态输水工程的开展改善了下游生态环境,这从下游胡杨年轮上得到了验证,但近15年的生态输水远未使下游胡杨年轮生长量达到1920年以前的水平,说明目前的生态输水对荒漠河岸林的恢复能力也是有限的; (4)在胡杨年轮对水资源的响应分析中,小波分析方法与历史文献记载得出了相同的结论。
英文摘要	Tree-ring is one of the important indicators of environmental evolution, which can obtain the climate data of global change of the past, and this method is very accurate and has good continuity, high resolution and reconstruction precision. This paper discussed the relationship between the surface runoff and tree-ring of Populus euphratica. The trend changes of runoff in the upper-middle reaches of the Tarim River and the tree-ring width of P. euphratica were analyzed by Mann-Kendall test. Combining the tree rings and the historical documents, the response of tree-ring in the lower reaches of the Tarim River to water supply was analyzed. The results showed that: (1) For nearly about 50 years(1957-2010), the tree-ring width showed a significant decline in the upper and middle reaches of the Tarim River, and the runoff has the same change trend. The statistical value of \| Zc \| was higher than 0.96. (2) The tree-ring width declined from 1913 to 2000, and it was more obvious during 1973-2001 and became the lowest level during the last 100 years. The formation, river course change and flowing back into old river course of the Layihe River in the middle-lower reaches of the Tarim River were all proved in tree-rings, which recorded the same as the historical documents. (3) The development of ecological water conveyance project improved the ecological environment in lower reaches of the Tarim River, which can be verified from the tree-ring. The treering width after 2000 never reached a high level as before 1920, which showed that the current ecological water is limited to the desert riparian forest recovery. (4) For response of tree-ring of P. euphratic to water supply, the wavelet analysis method and historical documents drew the same conclusion.
