Abstract Population age structure and spatial pattern are central issues in population ecology. In this study, Haloxylon ammodendron populations in two typical habitats along northwestern edge of Junggar basin were investigated. Using data collected from 0.75-hm2 plots, we determined the diameter class structure, static life table, survival curves and spatial distribution pattern of the two populations to analyze the distribution characteristics of Haloxylon ammodendron population in this reign. It was found that the diameter class structure of the two Haloxylon ammodendron populations were significantly different. Most individuals (96.21%) of population in piedmont Gobi were concentrated in theⅠ,Ⅱ,Ⅲ diameter classes. No individuals were in Ⅷ, Ⅸ, Ⅹ diameter classes. This population had a short development time and it was in the growing period. A lot of individuals (63.38%) of the population in the bottom of the dry lake were in theⅠ,Ⅱ,Ⅲ diameter classes and some (9.39%) were in Ⅷ,Ⅸ,Ⅹ diameter classes. We hold that the population had a longer development time and it was in the stable period. Spatial pattern analysis showed that the Haloxylon ammodendron populations in different habitats appeared clump distribution. And at different developmental stages, with the increase of the diameter classes, the distribution pattern changed from clump to random or even. The results indicated that significant differences of population structure and spatial distribution pattern were found between Haloxylon ammodendron populations in different habitats. It was the synthesis effect of population history, species traits, environmental conditions and disturbance.
