中文摘要	心叶驼绒藜（Ceratoides ewersmanniana）和梭梭（Haloxylon ammodendron）是古尔班通古特沙漠的建群种和优势种，是重要的防风固沙植被。应用分形理论中的计盒维数对古尔班通古特沙漠南缘不同生境的2个样地心叶驼绒藜和梭梭种群空间格局进行分析比较。结果表明，样地A和B心叶驼绒藜种群空间格局的计盒维数分别为1．7090、1．5270，梭梭为1．4063、1．5686；心叶驼绒藜占据和利用空间的能力较强，梭梭相对稍弱。样地A和B2种灌木种间空间格局的计盒维数相差很小，分别为1．7805、1．7357，均大于单种灌木种群空间格局的计盒维数，表明心叶驼绒藜和梭梭种群作为一个整体对空间的占据和利用能力更强，且在2样地间生态功能相当。
英文摘要	Ceratoides ewersmanniana and Haloxylon ammodendron were the edificators and dominant species in the Gurbantunggut Desert, playing an important role in wind breaking and sand fixing. Box-counting dimension method of the fractal theory was used in comparative analysis of spatial distribution of the populations of the two shrub plants in two sample plots （200 m * 200 m）, different in type of habitat. Results of the analysis indicate that the box-counting dimension of spatial distribution of the population of C. ewersmanniana was 1. 709 and 1. 527 0 in plot A and B, respectively, and of H. ammodendron, 1. 406 3 and 1. 568 6, respectively. All in all, the former was comparatively higher than the latter in capability of occupying and exploiting space. The box-counting dimension of interspecies spatial distribution of the two shrub plants varied slightly between Plot A and Plot B, being 1. 780 5 and 1. 735 7, respectively, both higher than the box-counting dimension of spatial distribution of the population of a single species, which suggests that when deemed as a whole, C. ewersmanniana and H. ammodendron populations were much higher in capability of occupying and exploiting space, and their ecological functions was similar in either Plot A or B.
