Abstract:

Quercus wutaishanica is warm temperate deciduous broadleaved forest region one of the typical vegetation types. Qwutaishanica vegetation types as a representative of Shanxi,  is the main part of shanxi forest. Past research focuses on the subject of Qwutaishanica results, the study of the herb layer seldom reported. The understory layer dominant species of Qwutaishanica community on Qiliyu of Taiyue Moutains, whose abundances clearly vary along environmental(altitudinal) gradients.Herbaceous plants highly responsive to changes in environmental conditions that reflect the dynamic relations between vegetation and environment. In this paper, using the method of sample, investigated the community of Qwutaishanica on Qiliyu of Taiyue Moutains, Shanxi. We used the results of this investigation to calculate species importance values and frequency, which were used to identify 27 dominant species in herbages. χ2 tests, together with association coefficient and percentage cooccurrence, were used to measure interspecific associations of the dominant species of herbaceous. Plant functional types (PFTS) were defined according to interspecific associations and cluster analysis of the dominant species. In studies of forest understory plant assemblages, designating PFTs according to dominant herbaceous species is feasible. Dominant herbaceous species formed seven PFTs: each with its unique spatial distribution and morphological characteristics, are identifiedⅠ.amphigenous Ⅱ.pelouseedge Ⅲ.wetsparse Ⅳ.gapdrought resistant Ⅴ.hilledge Ⅵ.alpine Ⅶ.dank. Plant functional types(PFTs) of herbaceous plants varies with altitude gradients, which reflect the relationship between Qwutaishanica and environment well.
