ABSTRACT

High elevation areas are sensitive and vulnerable to climate change and exhibited relatively rapid changes in response to warming involving changes of floristic composition, species upward migration, shrub and tree encroachment and surface area changes. For this reason, it is important to provide quantitative studies as tools allowing a long-term monitoring of vegetation in response to climate change. The Stelvio Pass area is a high elevation site located in the European Alps, and a unique case study on the alpine range providing historical detailed information on vegetation with the availability of phytosociological maps of vegetation elaborated in 1953 and 2003. Here we show and describe an updated and detailed phytosociological vegetation mapping which will constitute a robust base for the monitoring and quantitative assessment of any impacts of future climate and/or environmental change as well as a tool to plan suitable vegetation and biodiversity conservation actions in the alpine environment.

摘要

高海拔地区对气候变化敏感且脆弱，并且在响应变暖时表现出相对快速的变化，包括植物区系组成的变化、物种向上迁移、灌木和树木的侵占以及表面积的变化。出于这个原因，重要的是提供定量研究作为允许长期监测植被以应对气候变化的工具。斯泰尔维奥山口地区是位于欧洲阿尔卑斯山的一个高海拔地区，是一个独特的高山地区案例研究，通过 1953 年和 2003 年制定的植被植物社会学地图提供了有关植被的历史详细信息。
