【摘要】 本研究选择不同海拔高度未退化的矮生嵩草草甸草地上的莎草科、禾本科、豆科功能群为研究对象,对不同功能群植物重要值与海拔的关系进行了研究。研究结果显示:随着海拔高度的逐渐升高,莎草科功能群的重要值总体上呈先增大后减小的趋势;禾本科功能群中大部分植物种的重要值随海拔的逐渐升高而增大;豆科植物功能群的重要值随海拔的升高,呈先增大后减小。更多还原

【Abstract】 This study choose the Cyperaceae,Gramineae,Leguminosae PFT( Plant Functional Type) in different altitude not degraded alpine meadow as the research object,the relations between IV( important value) and elevation was studied. The result showed that: with the increasing altitude,IV of Cyperaceae PFT is generally first increased and then decreased; IV of Gramineae PFT as the altitude gradually increases; IV of Leguminosae PFT with the increase of altitude,increase at first and then decrease.更多还原
