中文摘要：

最大的 latewood 密度(MXD ) 上的温度和降水的影响主要在这份报纸被讨论，基于从威信河盆的 Picea schrenkiana 的样品， Xinjiang，中国。在来自 Shihezi 气象学的车站的 MXD 和仪器的记录之间的关联分析证明 MXD 是断然与在整个在高举起的成长季节的吝啬的最大的温度有关。比较地，在低高度的戒指宽度被降水在 5 月 6 月限制。由 MXD 序列的合成年表高度在 7 月 8 月与吝啬的最大的温度被相关(r = 0.54， p < 0.001 ) ，它然后被合成年表重建。重建的温度，观察价值，和干旱上的比较分析索引() 当时，表明降水将影响 MXD 绝对值比 1.5 大(即， |Is|> 2.5 ) 在到 1.5 的 1953-2008 A.D 或为 2-3 的结束的时期连续的年。反应特征在学习区域与半干旱的气候被连接。在一单个年或极端干的连续的年里，降水的缺乏将限制 latewood 房间墙变厚并且因此影响 MXD。极其重要如果一张 MXD 年表被瞄准重建温度历史，在采样地点的潮湿条件应该谨慎地被考虑。

英文摘要：

The influence of temperature and precipitation on maximum latewood density （MXD） was mainly discussed in this paper, based on the samples of Picea schrenkiana from the Manas River Basin, Xinjiang, China. The correlation analysis between MXD and instrumental records from the Shihezi Meteorological Station showed that the MXD was positively related to the mean maximum temperature throughout the growing season at high elevations. Comparatively, the ring-width at low altitudes was limited by the precipitation in May-June. The composite chronology by MXD sequences was highly correlated with the mean maximum temperature in July- August （r = 0.54,p 〈 0.001）, which was then reconstructed by the composite chronology. The comparative analysis on the reconstructed temperatures, observed values, and drought indices （Is） revealed that precipitation would affect MXD when the absolute value of Is was greater than 1.5a （i.e., ｜Is｜ 〉 2.5） in the period of 1953-2008 A.D. or close to 1.5σ for 2-3 consecutive years. The response characteristics are linked with the semiarid climate in the study area. In a single year or consecutive years of extreme dryness, the lack of precipitation would limit the thickening oflatewood cell walls and thus impact the MXD. All in all, if a MXD chronology is aimed to reconstruct temperature history, the moisture conditions at the sampling site should be considered prudently.
