Abstract

The thirty-eight vegetation samping date were calculated and analyzed in the lower reaches of Tarim River.The results showed that there were 14 main species including Populus euphratica,Tamarix ramosissima,Tamarix hispida,Lycium ruthenicum,kareliniacaspica,Alhagi pseudoalhagi and so on.The species is less.By analyzing the important values,these species' s position and role were measured in plant community.By 2×2 contingency table and VR and X2 and r-test,the 14 species' s associations and correlations were measured.The results showed that total associations were unremarkable positive in the lower reaches of Tarim River.Among the species it was unremarkable positive and negative association.The results showed that the plant community was juvenile and immature woodland.It showed the character of the pioneer woodland.The results also showed that the species could be divided into three biological groups in the lower reaches of Tarim River.
