Accelerating high-latitude climate warming drives shrub expansion in open landscapes and alters species distributions and compositions of plant communities. Simultaneously, various land use practices cause disturbance to the vegetation. However, not much documentation exists on how long-term intensive land use disturbance modifies high-latitude vegetation under climate warming. Here, we study how the composition of boreal mountain plant communities has changed during three decades in response to heavy land use disturbance, related to ski resort construction and management, and how these changes compare to those observed in adjacent less disturbed communities.

人为干扰改变了当代气候变暖下北方山区植被的长期变化

加速高纬度气候变暖驱动了开阔景观中灌木的扩张，并改变了植物群落的物种分布和组成。同时，各种土地利用方式对植被造成干扰。然而，关于长期集约化土地利用干扰如何在气候变暖下改变高纬度植被的文献并不多。在这里，我们研究了北山植物群落的组成在三个十年中如何因严重的土地利用干扰而发生变化，这与滑雪胜地的建设和管理有关，以及这些变化与在邻近较少干扰的社区中观察到的变化相比如何。
