Distribution Pattern of Tamarix ramosissima Ledeb at High Salt Land in the Ejina Oasis,Inner Mongolia,China

The research on impact of Tamarix ramosissima Ledeb distribution pattern on community structure and dynamics is very important to elucidate the ecosystem formation and maintenance as well as the community stability and succession law of the T.ramosissima Ledeb.Through continuous quadrat surveying,χ2test and variance analysis of T.ramosissima Ledeb,a main desert riparian forest species in the Ejina oasis,we carried out a study of the distribution pattern of T.ramosissima Ledeb.The results showed that the distribution of T.ramosissima Ledeb belonged to a cluster distribution type,and the pattern scale was 8 m×8 m;the pattern intensity of T.ramosissima Ledeb decreased with increasing of pattern scale.It suggested a relatively low cluster intensity depended on the species density.
