The studies on Pattern of the Xeric Shrub Population in Mosowan Desert

From the point of view of statistics ecology,the author has detected and studied the pattern of xeric shrub population in Mosown desert by the methods of GreigSmith contiguous grid of quadrats and blocksizc analysis of variance. The results show that the pattern of Halo-c,lon ammodendron is random distribution at the primary phase of growth of population,Contagious distribution at the metaphase on medium scale,random distribution on smaller scale and regular distribution on large scale in climax.Reaumuria soong orica and Anabasis aphylla shows clear evidence of random distribution.Calligonum leucocladum shows morphological pattern of contagious distribution at normal site.In mictium of two population the patterns of R. soongorica and II. ammodendron are mainly unrelated.
