准噶尔盆地中部琵琶柴(Reaumuria soongorica)群落的生境研究

琵琶柴(Reaumuria soongorica)在我国荒漠区分布较广,是极为耐旱的群落类型之一,这一群落均见于干旱区低平地形,且均着生于淤积粘土中。调查证实:地表短期积水是琵琶柴幼体发生与建群过程的必要条件,但其成株生存环境,通常极为干燥,在其生活周期的不同发育阶段。生境呈现明显的异质现象。

STUDY ON THE HABITAT OF Reaumuria soongorica COMMUNITY IN ZHUNGGER BASIN

Reaumria soongorica community is widely distributed in desert zone of China.It is one of the drought-enduring plant communities. This community grow in low ground of landform and on the warp clay soil in Zhungged basin. Investigation had proveded: as the germination of its seeds and the seeding procces of ecesis, it is needed that the plnce that the water stocl on the surfaoe in a short time. But the habitat of sexnal maturity of brush usual grows on the dry clay soil, and so in different develomental stage of life cycle of the Reaumuria soongorioa, it will be growing in dissimilar habitat.
