摘    要:主要研究了流动沙兵采用草方格固沙结合播种小叶锦鸡儿后,上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降有大的变化,从5种增加到23种;在生活型组成结构上,一年生植物占约对优势,但所占比例随着时间的变化有8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

关 键 词:人工群落  植被恢复  小叶锦鸡儿  流动沙丘  治理

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 (in 2 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.
Keywords:Sandy land  Artificial plant community  Vegetation restoration  Ecological process    Caragana microphylla
