摘    要: 本文通过对秦岭南坡旬河流域及其邻近地区森林植被调查资料的统计分析和研究,以地形海拔高度、土壤pH值以及土壤有机质含量作为森林环境梯度区分指标,运用主分量分析以及判别分析等数学手段,在该流域内划分出9种不同生境(立地)类型。以此9种生境类型为基准,对比林下植物种在各类型样地中的出现与否及其盖度特征,经反复调整,筛选出31种具生境指示意义的种子植物,并由此建立起相对应的9个生态种组。最后简要介绍了各种组的生境特征指示范围,以期为生产经营工作中野外识别不同生境类型提供帮助,推动植被生态学研究的深入。

关 键 词:旬河流域  秦岭山脉  生态种组  森林植被

Abstract:Using topographical elevation, pH value and humus content in surface soil as environmental gradient indices, this paper has statistically analyzed field investigation data of forest vegetation in Xunhe River basin and its adjacent area, south aspect of Qinling Mountain, to differentiate forest habitat. 9 habitat types (sites) has been classified in the area by means of principal components analysis (PCA) and discriminant analysis (DA). On the basis of those 9 habitat types, 31 species with environmentally indicative significance have been selected out of all the undergrowth species in quadrats of every type according to species' present-absent and coverage index. 9 ecological species groups corresponding to 9 types respectively have been established through repeated adjustment process. The indicative amplitude of each group on habitat types has also been reviewed to help distinguish different sites in fieldwork of productional or management parposes.
Keywords:Xunhe River basin  Qinling Mountain  Ecological species group  Forest vegetation
