摘 要 ：珍珠(Salcola passerina)植物群落广泛分布于鄂尔多斯西部、阿拉善东部和河西走廊等地区。同红砂(Reaumuria soongorica)群落、泡泡刺 ia sphaerocarpa)群落和合头草(Sympegma reglii)群落组成该地区荒漠植被的主要部分。在生产上珍珠群落是较好的荒漠草场之一。前人对本区珍珠荒漠群落有一些研究,如《治沙研究》和《中国植被》等(中国植被编辑委员会,1980;中国科学院治沙队,1958;李博,1962;黄银晓等,1962)。但还未见到较详细的群落学研究报道。因此,在这里报道我们的研究,为荒漠植被的研究和放牧利用提供参考。
Abstract:This article deals with the geographic distribution, ecological circumstances, composition of plant species, structure and classification of plant community of Salsola passerina, and evaluates its economic values.The study showns that the plant community of Salsola passerina is one of the wide distributed plant communities in China‘s desert steppe zone and eastern desert zone. Its species components are more abundant and structure is more complex. Quite a number of plant species which has a higher yield of ...
