With the sand fixed, the community succession was ranked from A. halodendron - annual herbage (pioneer stage, coverage < 10%, Shannon-Wiener index 0. 33) to A. halodendron - perennial grass (coverage 30% to approximately 35%, Shannon-Wiener index 0. 56), and then to A. frigida - A. scoparia + perennial grass (steppe community, coverage 40% to approximately 45%, Shannon-Wiener index 0. 59). The A. halodendron population on shifting sandy land and that planted 5 years ago showed growing age distribution, that planted 18 years ago showed stable age distribution, and that on semi-fixed and fixed sandy lands showed declining age distribution. The results proved that A. halodendron populations had different ecological effects on A. halodendron community. %K Artemisia halodendron %K Different kind sandy land %K Community type %K Age structure
