摘　　要：分析新疆地区现已取得的树轮水文学研究成果,选取基于树轮宽度重建的阿尔泰山、天山、昆仑山和塔里木河流域等区域共14条河流径流量序列,对各序列的水文历史变化特征进行对比和讨论,并对进一步开展新疆地区树轮水文学研究提出了建议和展望。研究结果表明:(1)水分是各流域树木径向生长的主要限制因子,且树木径向生长与河流径流量之间普遍存在正相关关系。(2)对新疆5个区域的河流径流量重建序列进行相关分析,发现阿尔泰山区域重建序列间的相关性较高,天山北坡次之,天山南坡最低。阿尔泰山与天山北坡径流量重建序列间亦存在较好的相关性。(3)14条河流径流量重建序列经31 a滑动平均处理后,结果显示同一区域内河流径流量序列丰枯变化的一致性相对较好。(4)5个区域内部径流量重建序列存在相同的极值年份,且重建序列的部分极值年份与历史记录的气候水文灾害相吻合。(5)新疆地区径流量重建序列的周期变化在高频上较为一致,均存在2~7 a的短周期,其径流量变化可能受到海陆大尺度气候振荡的影响。Through reviewing the dendrohydrological studies in Xinjiang,we selected 14 tree-ringwidth(TRW)based streamflow reconstruction series to understand hydrological characteristics over this region.The results suggest that:(1)The moisture condition is the main limiting factor for the TRW growth of trees in all river basins,and there is generally a positive correlation between TRW and streamflow.(2)The correlation analysis of five subregional streamflow reconstruction series show that there is a high correlation between the regional reconstruction series in the Altay Mountains,followed by the northern slope of Tianshan Mountains and the southern slope of Tianshan Mountains.There is also a good coherence among series in Altay Mountains and the northern slope of Tianshan Mountains.(3)The low-frequency variability(31-year moving average)of the 14 streamflow reconstruction series in the same region is relatively similar.(4)The streamflow reconstruction series in the five subregions indicate the same extreme years,and the detected extreme years are in part consistent with the climatic and hydrological disasters recorded in history.(5)The periodic changes of the 14 streamflow reconstruction series in Xinjiang are consistent in high-frequency domains.The 2-7 year periodic changes of all 14 series also suggest that the variations of streamflow in Xinjiang are likely affected by large-scale oceanic and terrestrial oscillations.
