Application of Grey Sequence to Study on the Relation between Environmental Factors and Species Diversity

Abstract

Abstract: Investigation was carried out to determine the effects of the different factors on undergrowth herb species diversity in Saihanba Forestry Centre. Grey sequence method was used to treat and analyze the data. The results are as follows: there are 79 undergrowth herb species in the survey area and the dominant species are mainly C. rigescens, E. cheiranthoides, C. chinensis; E. pretense, T. mongolium, T. aquilegifolium,etc. are common species and I. denticulate, A. cathayensis,etc. are the occasional species. Height and DHB have the largest effects on species richness next to altitude and slope.

Key words: grey sequence, species diversity, undergrowth vegetation
