佛坪国家级自然保护区植被垂直带谱及其与邻近地区的比较

在首先确定垂直带划分的原则和将佛坪自然保护区植被划分为落叶阔叶林带、中山小叶林带和亚高山针叶林带３个垂直带，各垂直带植被物种组成的区系、生活型组成和物种多样性的差异证实了这种划分的合理性。与邻近地区植被垂直带谱的比较表明，佛坪自然保护区的植被垂直带谱与秦岭北坡有明显差异，表现为典型的暧温带与北亚热带过渡区域的植被景观，虽然基带以上各植被带暖温带特色很明显，但其植被属性应是北亚热带的。

VERTICAL ZONE SPECTRUM OF VEGETATION IN FOPING NATIONAL RESERVE AND THE COMPARISON WITH THE ADJACENT AREAS

After ascertained the partition principle of vertical vegetation zone,the vegetation of Foping National Reserve (FNR) was divided into three vertical zone:deciduous broad leaved forest,middle mountain birch forest and subalpine coniferous forest.This divide was confirmed by the significant different of species composition of flora,life form spectrum and species diversity of each vertical zone.The comparison of the vegetation vertical spectrum of FNR with that of the adjacent areas showed that it is very different from the vegetation vertical spectrum of the north slope of Qinling Mountain and that the vegetation landscape of FNR is the typical vegetation landscape of ecotone of warm temperate zone and north subtropic zone.Although the vegetation above the radical belt in FNR presented some traits of vegetation in warm temperate zone,the property of vegetation in FNR belongs to north subtropic zone.
