摘要
新疆荒漠区主要旱生乔灌木种群空间分布的格局,取决于这些树种本身的生命活动节律与无机生态因子的配合。例如胡杨(Populus euphratica).梭梭(Haloxylon),柽柳(Tamarix)等旱生类群,就总体而言对本区的生境是适应的,但由于具体地段无机因子的组合及其在时空分配的差异,从而制约这些植物在空间的侵移与建群过程,并在很大程度上制约其空间分布的格局。
The pattern of spatial distribution of the xeric arbor and bush in thedesert of Xinjiang is determined by the coordination of plants' life rhythmwith inorganic ecological factor. Generally speaking, xeric plants, such as Populus euphratica, Haloxylonand Tamarix etc. are adapted to their habitat in this area. But the ecologicalfactor heterogeneit in time and space in this area controlls immigrating andestablishing of the plant community, so that the distribution of patterns iscontrolled in a great way.
