由在各种各样的地理规模比较长期的树戒指生长，我们能在树生长上弄明白环境变化的效果，并且在全球、地区性的气候得到对可能的变化的森林生态系统的回答的理解。到空气温度和降水的 Picea schrenkiana 和它的关系的光线的树戒指生长在西北的中国在 Tianshan 山的北方斜坡上越过经度横断被调查。树戒指样品被收集，剩余年表从西方沿着减少的降水的一个坡度为三个不同区域被开发到东方。反应功能分析被进行确定在树戒指年表和气候变量之间的关系例如从 1961 ～ 1998 的每月吝啬的温度和每月的降水，用 PRECON 软件编程序。年表的统计特征证明在这研究构造的三张年表包含了重要环境信号并且是很好合适的在树生长和森林生产率上揭示气候的变化的影响。年度戒指宽度变化在三个地点之中是类似的，但是可变性在东方是最大的。这研究证明在 Tianshan 山的 Picea schrenkiana 的生长趋势没跟随一个一致模式。反应功能分析显示在所有三个区域，降水在之中是主管在树生长和气候的因素之间有重要关联。与减少的降水，到增加温度的树戒指宽度的反应变化了从一对否定关联积极。至于降水，到树戒指宽度的积极关系总是统治。与增加的温度和减少的降水，到树生长的降水的重要性将增加，这能被期望，并且到环境变化的树生长的反应将也增加。这研究强调地区性规模的调查的重要性进生物圈气候相互作用。这研究的结果显示了树戒指的实质的增长由于在东方区域的更温暖、更湿的气候的光线的生长。然而，气候变化将在西方的区域在森林生长和主要生产上有更少的效果。

英文摘要：

By comparing the long-term tree-ring growths at various geographic scales, we can make clear the effects of environmental variations on tree growth, and get an understanding of the responses of forest ecosystems to the possible changes in global and regional climate. Radial tree-ring growth of Picea schrenkiana and its relationship to air temperature and precipitation were investigated across longi- tude transects on the north slopes of the Tianshan Mountains in northwestern China. Tree-ring samples were collected and residual chronologies were developed for three different regions along a gradient of decreasing precipitation from west to east. Response-function analysis was conducted to quantify the relationships between tree-ring chronologies and climate variables, such as monthly mean temperature and monthly precipitation from 1961 to 1998, using the PRECON software program. The statistical characteristics of the chronologies showed that the three chronologies constructed in this study con- tained significant environmental signals and were well suitable to reveal the impacts of climatic change on tree growth and forest productivity. Annual ring-width variations were similar among the three sites, but the variability was greatest in the east. This research showed that the growth trends of Picea schrenkiana in the Tianshan Mountains have not followed a uniform pattern. Response-function analy- sis indicated that there were significant correlations between tree growth and climatic factors in all the three regions, among which precipitation was the principal. With decreasing precipitation, the response of tree-ring widths to increasing temperature changed from a positive to a negative correlation. As for precipitation, the positive relationship to tree-ring width always dominates. It could be expected that with increased temperature and decreased precipitation, the importance of precipitation to tree growth would increase, and the response of tree growth to environmental changes would also increase.
