摘要：

根据西佛爷池(海拔3410 m)剖面的有机地球化学指标, 重建太白山高山带过去2000年的气候变化。对采自该剖面的样品进行孢粉分析, 并结合太白山跑马梁(海拔3556 m)、三清池(海拔3080 m)和芳香寺(海拔3000 m)剖面的孢粉数据, 进行聚类分析, 探讨高山带不同海拔植被对气候变化响应规律。结果表明, 不同海拔植被对相对冷干气候的响应有更好的一致性, 且林线过渡带内这种一致性更明显。随着现代升温期的到来, 植被对气候的响应主要受高程影响。研究结果可为认识晚全新世以来高山环境系统的气候?植被耦合关系提供一定的参考。

Abstract:

Based on organic geochemical indicators of a lake-sediment profile from Western Foye Chi (3410 m), the study reconstructs the climate change of the Taibai Mountain alpine zone during the past about 2000 years. In order to explore the similarities and differences of vegetation response to the climate change at different altitudes in the alpine zone, pollen analysis of the profile was carried out, and cluster analysis was performed on the results in combination with the published pollen data of Paomaliang (3556 m), Sanqingchi (3080 m) and Fangxiangsi (3000 m) in Taibai Mountain. These analyses suggest that the responses of the vegetation to relatively cold and dry climate have good consistency at different altitudes, which is even more noticeablein the transition zone of timberline. Besides, along with the modern warming period, the responses of vegetation to climate change are mainly determined by the altitude. This study can provide some references for understanding the coupling relationship between climate and vegetation of alpine environmental systems during the Late Holocene.
