Abstract Based on the investigation into natural Haloxylon ammodendron in Minqin desert area, the population growth of Haloxylon ammodendron on the sandlot and alkali-saline soil, the relation between population growth and soil moisture, as well as its population structure and spatial distribution, were analyzed. The result indicated that population growth of natural Haloxylon ammodendron on the sandlot is obviously superior to that in alkali-saline soil, with density and coverage of population at the sandlot being 47 individuals per hectare and 2.1%, while that in alkali-saline soil being 24 individuals per hectare and 1.2%. This result is well compatible to soil moisture. The age structure of Haloxylon ammodendron population either on sandlot or on alkali-saline soil took a declining trend. So it is imperative to adopt favorable measures to protect Haloxylon ammodendron population, otherwise it will be replaced by other concomitance species with better regeneration power. Haloxylon ammodendron population is distributed in a clustered pattern on the sandlot while distributed evenly on the alkali-saline soil. This is closely related not only to inter-species and intra-species competition caused by different density of Haloxylon ammodendron population, but also to habitat environment.
