| Abstract: | The relationship between the characteristics of plant community and the environmental factors in the Dongkemadi River basin was studied.The results show that,the 112 vegetation plots were divided into five plant communities by TWINSPAN,and,for the compositions of species life forms,the perennial herbs(87 species) come first and annual or biennial herbs(19 species) second.The cumulative explanation percentage of the biodiversity,biomass,coverage and the environmental characteristics reaches 88.5%.The respons... |
