【目的】

揭示气候变化背景下岷山中段不同坡向岷江冷杉Abies fargesii var. faxoniana径向生长对主要气候因子的响应差异及其稳定性，为认识亚高山针叶林生长对气候变化的适应机制及其保护管理提供科学依据。

【方法】

基于48根采自岷山中段东坡和西坡的岷江冷杉树木年轮样芯，利用R语言中dplR扩展包建立树木年轮年表并去除生长趋势，用Spearman回归分析方法和21 a滑动相关分析方法研究1951—2022年岷江冷杉对月均降水、月均气温、月均高温和月均低温的响应性与稳定性以及动态变化。

【结果】

东坡和西坡的岷江冷杉标准年表统计特征值有差异，其中西坡岷江冷杉对主要气候因子响应的敏感性更高。两者与主要气候因子的响应关系、响应时段及稳定性不一致：东坡岷江冷杉与上年5月降水量的相关关系在21世纪后达到显著水平，与当年9月降水量的显著负相关关系在1975年后逐渐减弱；而西坡岷江冷杉与当年6月和9月降水量的相关性整体不稳定，且与上年8月降水量呈显著正相关。东坡与西坡岷江冷杉径向生长均受上年7—8月气温限制作用和当年休眠期气温的促进作用，而西坡岷江冷杉对气温的响应敏感性更高。此外，西坡岷江冷杉与上年7月平均气温的显著负相关关系呈减弱趋势，而东坡岷江冷杉与上年7月平均气温的负相关关系则随着时间变化表现出不稳定性。

【结论】

岷山中段东坡和西坡岷江冷杉对降水量、气温的响应特征均不一致，且响应关系在不同时间尺度上表现出明显的非稳定性和动态变化特征，表明坡向差异是影响岷江冷杉径向生长气候响应的重要因素。

【Objective】

To understand how radial growth of Abies fargesii var. faxoniana on different slopes in the mid-Min mountains responds to major climatic factors, how stable these responses are under climate change, and to provide a scientific foundation for elucidating the adaptive mechanisms of subalpine coniferous forests in response to climate change, thereby informing their conservation and management strategies.

【Method】

Using 48 tree-ring cores collected from the east and west slopes of the mid-Min mountains and using the dplR package in R, tree-ring chronologies were developed and growth trends were removed. Spearman correlation analysis and 21-year moving correlation analysis were applied to examine the responsiveness and stability of A. fargesii to monthly precipitation, mean temperature, mean maximum temperature, and mean minimum temperature from 1951 to 2022.

【Result】

Significant differences in the statistical characteristics of the standard chronologies between the eastern and western slopes were present. A. fargesii on the east slope exhibited higher sensitivity to the key climatic factors, with divergent response relationships, response stability and temporal patterns compared to that on the west slope. The negative correlation between the eastern-slope A. fargesii chronology and previous May precipitation became significant after the beginning of the 21st century, whereas the significantly negative correlation with current September precipitation gradually weakened after 1975. Meanwhile, trees on the west slope displayed unstable correlations with current June and September precipitation, but maintained a significant and stable positive association with previous August precipitation. Radial growth on both slopes was limited by July-August air temperatures of the previous year but promoted by air temperatures during the dormant period and growing season of the current year, with trees on the western slope more sensitive to air temperature. Trees on the west slope exhibited a gradual weakening of the previously significant negative response to the previous July mean temperature, while those on the east slope showed temporal instability in the same correlation.

【Conclusion】

The response patterns of A. fargesii on the eastern and western slopes of the central Minshan mountains to precipitation and air temperature were inconsistent, and the response relationships exhibited marked non-stationarity and dynamic variability across different time scales, indicating that slope aspect is an important factor influencing the climatic response of radial growth in A. fargesii.
