Factors influencing the floristic diversity in the alpine region

The present laureate work investigated the influence of the complex of abiotic site factors — in particular the soil chemical state — and the use by grazing animals on the floristic diversity of homogeneous plant populations in the alpine area. The 57 alpine areas studied are located in the Gesäuse National Park and cover a very broad ecological and thus floristic spectrum. The vegetation surveys were carried out in 2005 according to the BRAUN-BLANQUET method (1964), the soil chemical analysis methods were based on the respective ÖNORM. The Laureat work is based on a subproject of the ALTER-Net Research Network and results from the cooperation between the Higher Federal Education and Research Institute for Agriculture Raumberg-Gumpenstein and the Gesäuse National Park.本获奖课题考察了非生物立地因子复合体（尤以土壤化学状态为核心）以及放牧动物利用行为对阿尔卑斯区域内同质植物种群区系多样性的影响。本次研究涵盖的57处阿尔卑斯区域均坐落于格萨乌斯国家公园（Gesäuse National Park）内，覆盖了极宽的生态梯度与相应的植物区系谱系。植被调查于2005年依照布朗-布朗克法（BRAUN-BLANQUET，1964版）开展，土壤化学分析方法则基于对应的奥地利国家标准（ÖNORM）。本课题依托ALTER-Net研究网络的子项目开展，其研究成果来自奥地利劳姆贝格-古彭施泰因农业高等联邦教育与研究学院与格萨乌斯国家公园的合作项目。
