四川卧龙自然保护区川滇高山栎矮林在海拔梯度上的植物种-面积研究

川滇高山栎矮林是我国横断山区特有的一种高山硬叶常绿阔叶林.应用植物种-面积原理探讨了四川省卧龙自然保区境内的川滇高山栎矮林在海拔梯度上的最小面积与最小面积所含的种数,结果表明:川滇高山栎矮林中草本植物、木本植物和维管植物的种-面积随海拔梯度的变化都各自表现出了一定规律性.此对硬叶常绿阔叶林研究提供了一定的理论基础.

Studies on the Correlation of Plant Species-area of Quercus Aquifolioides Dwarf Forest with Altitude Gradient at Wolong Nature Reserve in Sichuan Province

Quercus aquifoliodes forest is a type of high mountain hard leaf evergreen broad-leaved forests distributing in Hengduanshan Mountain,this paper researches correlation of the minimal areas and the numbers of species inside the minimal areas of Quercus aquifoliodes dwarf forest with altitude gradient at Wolong Nature Reserve in Sichuan Province by the use of Species-area theory.These conclusions indicate that the minimal areas and the numbers of species inside the minimal areas vary regularly with the change of altitude gradient on vascular plants and woody species and grass species respectively,in order to provide some theoretic basis with the researches on high mountain hard leaf evergreen broad-leaved forests.
