Flora and species diversity of epilithic mosses on rock desertification in the Puding karst area
摘要
Abstract
This work studied the flora and species diversity of epilithic mosses in karst rock desertification ar ea in Puding,Guizhou Province.The results show that there are 8 families,24 genera and 54 species of epil ithic mosses.Among them,the pottiaceae and hypnacea are the dominant families.Barbula,btyum,campy lopus,pseudosymblepharis broth and rhynchostegiella are dominant genera.There is significant change in richness index of species,ranging 0.471 to-0.297.The evenness index is inconspicuous,which ranges from 0.671 to 0.566;and the abundance of the epilithic mosses in the ecologically damaged area is significantly lower than long-term observation of samples(E) of soil and water conservation.There are 4 types of life forms,including cluster pattern (53.8%),wefts (26.90%),mats (11.5%) and pendants (7.7%),in which the cluster pattern is absolutely dominant.The result of PCA shows that through quadrat analysis,the ecology and distribution of the epilithic mosses are different.关键词
