植物物种的空间格局和关联对于揭示物种之间以及物种与环境之间的相互作用具有重要意义，因此对于理解温带荒漠植被中物种相互作用和潜在的生态过程具有重要意义。本文采用g（r）函数对准噶尔盆地南缘荒漠-绿洲交错带3个1 hm 2荒漠植物样地中4种优势木本植物的空间格局和联结性进行了研究。完全空间随机性零模型表明，4种植物在小尺度上表现出显著的聚集，
Spatial patterns and associations of plant species are important for revealing how species interact with each other and with the environment, and hence have important implications for the understanding of species interaction and underlying ecological processes with apparent patterns in temperate desert vegetation. In this paper, the function g (r) was used to characterize the spatial patterns and associations of four dominant woody species in three 1-ha desert plant plots in the desert-oasis ecotone of South Junggar Basin, NW China. The complete spatial randomness null model showed four species exhibited significant aggregations at small scales (
