中文摘要	应用地统计学原理和方法，以莫索湾南缘沙漠为研究区，对心叶驼绒藜（Ceratoides ewersmanniana）、梭梭（Haloxylon ammodendron）、琵琶柴（Reaumuria soongorica）、沙拐枣（Calligonum leucocladum）4种优势灌木的空间分布格局进行定量研究。结果表明：心叶驼绒藜主要分布于丘底和丘坡，分布介于集群分布和均匀分布，变程31．44m，各向同性；梭梭主要分布于丘坡和丘顶，呈自相关性很强的集群分布，变程89．03m；琵琶柴主要分布在丘底，为中等程度的集群分布；沙拐枣在该区分布频度较低，各向异性，属于随机分布。该地区灌木分布受沙漠与绿洲环境的共同作用，心叶驼绒藜和梭梭在该地区适应良好，分布环境的互补性强，搭配建植防风固沙的生态效益明显。
英文摘要	This paper lucubrates quantitatively the spatial distribution patterns of 4 dominant shrub species including Ceratoides ewersmanniana, Haloxylon ammodendron, Reaumuria soongorica and Calligonum leucocladum in the study area, the southern marginal zone of the Mosuowan Desert based on the field investigation and applying geostatistical theory and methods. The results reveal that the distribution of these shrubs is closely related to the environment. The spatial distribution patterns of these shrubs are that C. ewersmanniana is mainly distributed in the inter-dune lowlands and on the dune slopes, belonging to cluster and uniform distribution with range of 31.44 m, and the distribution is isotropic; H. ammodendron is mainly distributed on sand dune slopes and tops with high spatial heterogeneity, belonging to cluster distribution with strong autocorrelation and range of 89.03 m; R. soongorica is mainly distributed in the inter-dune lowlands, belonging to mid-cluster distribution; and the distribution frequency of C. leucocladum is low and anisotropic, and the distribution is random. After concluding, it is considered that the distributional patterns of these shrubs are jointly affected by both desert and oasis ecosystems, especially the a- daptability of C. ewersmanniana and H. ammodendron in the study area is high, and these two species can be al- ternately planted as the windbreaks for fixing sand.
