| 摘 要： | 探讨了枯草层在盐碱植物演替过程中的生态作用，枯草层可改善盐碱土的理化性，为其它植物的侵入，定居创造了良好的生境条件，枯草层可改变盐碱的植物群落的种类组成及群落特征，使盐碱植物群落逐渐演变成盐碱植物＋羊草群落，最后形成羊草群落，在盐碱植物群落中人工建立枯草层，可加快植被恢复的速度。

| Abstract: | The ecological effect of litter layer on salne-alkali plant community succession were explored in this paper. Litter layer could improve the physical-chemical quality of saline-alkali soil, which created good habitat condition for the invasion and colonization of plant. Litter layer could change the floristic compostion and the characteristic of saline-alkali plant community and caused saline-alkali plant community to evolve gradually saline-alkali plant + Aneurolepidium chinense community, and then to develop Aneurolepidium chinense community lastly. The artificical litter layer built in saline-aklali plant community could quickened vegetation recovery. |
