| 摘 要： | 通过分析总结在中国阿尔泰山区域已取得的树轮气候学和树轮水文学研究成果，选取了5条气温重建序列，3条降水重建序列和2条径流量重建序列，对各序列在全频域、低频域和高频域的相关系数、序列的阶段变化、极值年份、周期等特征展开了讨论和对比，并对阿尔泰山气候的年代际变化进行了分析。结果表明：（1）目前在阿尔泰山开展的气温重建中，重建时段均在树木生长季内，5条气温重建序列显示在1690年代-1700年代、1730年代、1780年代-1790年代为偏冷时期，1710年代-1720年代、1800年代-1830年代、1940年代-1960年代及1990年代以来为偏暖时期。有3条序列指示1830年为暖年，1698年、1784年、1911年、1985-1986年为冷年。（2）3条降水重建序列显示，1830年代-1860年代经历了一段降水量相对平稳的时期，1870年代-1900年代为持续时间最长的干旱时期，1900年为干旱年。（3）2条径流量重建序列显示，1730年代和1810年代-1820年代为丰水期，1750年代和1870年代-1890年代为枯水期，降水量对哈巴河径流量有较大影响。（4）年代际气候变化分析显示，阿尔泰山在1830年代-1990年代以暖干为主，1990年代以后进入了暖湿时期。

| Abstract: | Due to the special geographical location and climatic conditions, Altai Mountains is rich in forest resources. Tree-ring has become the primary method for studying the historical climate and hydrology change characteristics in this region. The dendroclimatological and dendrohydrology researches are concluded by analyzing the Altai Mountains of China summary in recent decades. To achieve better results, 5 reconstruction of temperature series, 3 reconstruction of precipitation series and 2 reconstruction of runoff series were selected for further research, and discussed and compared the stages, extreme years and cycles of these reconstructions. The results can be included the following four parts:(1) Reconstructed periods of temperature in the Altai Mountains all belong to the growing season. Five temperature reconstructions showed that 1690s-1700s, 1730s, 1780s-1790s were cold periods, and 1710s-1720s, 1800s-1830s, 1940s-1960s and 1990s were warm periods. Three indicated that the year 1830 was warm, while the year 1698, 1784, 1911, 1985-1986 were cold. (2) Comparing three precipitation reconstructions, we found that the precipitation during 1830s-1860s was relatively stable; 1870s-1900s was the longest dry period. Above precipitations all showed that the year 1900 was dry. (3) The wet epochs for both two runoff reconstructions occurred in 1730s and 1810s-1820s. The dry epochs lied in 1750s and 1870s-1890s. Precipitation in the Altai Mountains has greater influence to runoff of the Haba River. (4) Analysis of climatic variations in decadal timescales showed that warm-dry was the main climate type during 1830s-1990s in the Altai Mountains. Climate became warm and dry in the 1990s. |
