Abstract

By using the combination of TWINSPAN and DCA,this paper classifies and ranks the plants in Zhangze Reservoir’s Wetland of Changzhi City into 8 associations that are located at different areas according to the moistures.The results of the classification and ordination reflect well the relationship between the types of plant associations and the environmental factors which are verified well in the two-dimension ordination diagram by DCA.The ordination axes of DCA reflect the gradient change of soil moisture,which shows that water condition is the main ecological factor that influences the plant association.
