Phyto-community Characteristics of the Dependent Environment of Dipteris shenzhenensis
摘要
Abstract
Dipteris shenzhenensis is a critically endangered(CR)plant distributed only in Shenzhen.The phyto-community analysis of this dominant community was studied and analyzed,and the results showed that:there were 85 species,73 genera and 49 families of vascular plants in Dipteris shenzhenensis community,the dominant species included Gordonia axillaris,Ilex memecylifolia,Cyclobalanopsis neglecta,Enkianthus quinqueflorus,Litsea rotundifolia var.oblongifolia,Dipteris shenzhenensis,Dicranopteris pedata;Plant individuals in this community decreased with the increase of tree height,showing an"Inverted J"type distribution,which was an obvious characteristic in subtropical areas.The diversity and evenness index of all life forms showed a trend of"high in the middle and low in the two ends";The T test of the species diversity index of different communities in the same area proved that there was no significant difference in diversity level between different communities,which belonged to the stable stage of ecological succession;Niche analysis revealed the survival status of Dipteris shenzhenensis in the community,indicating that this species was not widespread,demanding for environment and poor competitiveness in resources,and there was a risk of extinction during community succession;Interspecific association analysis revealed the interspecific relationship between this species and other dominant herbs,and identified possible complementary and competitive plants.关键词
