| 摘 要： | 我们调查了安西荒漠保护区内相邻的4种典型植物珍珠猪毛菜（Salsola passerina ）、合头草（Sympegma regelii ）、红砂（Reaumuria soongorica ）、泡泡刺（Nitraria sphaerocarpa ）个体大小与相对距离，通过对10种组合的个体大小与距离的回归分析，研究其彼此间的相互关系。结果显示：4种植物大小与距离之间是正相互关系，即竞争关系；种内竞争的重要性高于种间竞争的重要性，且竞争物种之间存在不对称性。此结果表明，物种间的这种竞争关系在一定程度上影响了荒漠地区植物群落的构建。

| Abstract: | We investigated size-distance data from four typical plants, Salsola passerina, Sympegma regelii, Reaumuria soongorica, Nitraria sphaerocarpa, in the Anxi Extra-arid Desert National Nature Reserve,Gansu, China. Ten combinations of the four species were studied. Regression analysis on the size-distance data of ten combinations was made to explore the relationship between them. The results showed that there was a positive relationship between the size and distance of the four species, and they competed with each other. Intraspecific competition was more severe than interspecific competition. And there was asymmetry competition between the species. The result suggested that competition affect establishment of plant community in the desert areas to some extent. |
