Abstract C. ewersmanniana is a kind of high-quality herbage in arid region, and the construction species of wind-sheltering and sand-fixing vegetation. In this paper, two representative samples of 200m 200m were set in south of Gurbantunggut desert. Ripley's K(d) function was used to determine the spatial pattern of population regeneration of C. ewersmanniana and its relationship with the three main shrub populations（H. ammodendron, R. soongorica, S. kaschgaricum）. In both samples, the spatial pattern of population recruitment was influenced greatly by the distribution of adult C. ewersmanniana. Adult and middle-aged C. ewersmanniana exhibited positive correlation with young C. ewersmanniana. C. ewersmanniana had positive correlation with S. kaschgaricum, but had negative correlation with H. ammodendron. Its correlation with R. soongorica was opposite in the two samples. We concluded that the population recruitment of C. ewersmanniana depended severely on adult plants. The spatial autocorrelation of its population recruitment was obvious within 30 m.This spatial autocorrelation was affected greatly by the environment and had weak ability to expand. In addition, the growth of four shrubs was determined by niche of each species, and was influenced greatly by water and other environmental factors. In the end, suggestion for ecological restoration of shrubs including C. ewersmanniana was raised.
