摘要/Abstract

摘要： 主要研究了流动沙丘采用草方格固沙结合播种小叶锦鸡儿后,小叶锦鸡儿人工群落形成和发展过程,尤其对群落中物种侵入过程和群落组织结构在35年间的变化情况做了详细分析.结果表明,人工小叶锦鸡儿群落不同发育阶段植物丰富度发生了很大的变化,从5种增加到23种;在生活型组成结构上,一年生植物占绝对优势,但所占比例随着时间的变化有逐渐减少的趋势,地面芽植物和地下芽植物的种类数和个体数所占比例均逐渐增加;物种多样性指数和均匀度指数均不断增长,而生态优势度指数逐渐降低.与天然植物群落的相似性指数随着发育年限的增加逐渐增加.同时也揭示了植被恢复过程中土壤理化性质的变化.

Abstract: The occurrence and development of artificial vegetation after mobile sandy dunes being fixed by adopting straw check combining with seeding Caragana microphylla were studied. Especially the process of species invasion and the changes of community structure in 35 years were analyzed in detail. The results showed that the species richness of artificial community of C. microphylla increased, from 5 species (iN₂ years) to 23 species in 35 years. In the structure concerning plant lifeform, therophytes were in dominant position, while the ratio of therophytes to all plant species had a tendency of decrease. The rates of species number and the quantity of hemicryptophytes and geocryptophytes increased gradually. Species diversity and community evenness indexes increased and ecological dominance index decreased gradually. The similarity index of the artificial plant community to natural one increased with age. The changes of physical and chemical property of soil were also discussed.
