摘要:
摘要 应用种群生态空间分布的分析方法,研究了青海湖四种主要湿地植物:杉叶藻(Hippuris vulgaris)、槽杆荸荠(Eleocharis valleculosa)、华扁穗莞(Blysmus sinocompressus)、碱蓬(Suaeda glauca)的空间分布格局及其动态.研究表明:杉叶藻、槽杆荸荠、华扁穗莞三种群由侵入期、定居初期到种群发育盛期的过程中,其集群程度先增大后减小,总体呈扩散的趋势;碱蓬种群,从幼苗到繁殖期,集群程度增大,呈聚集的趋势.说明前三种植物的克隆繁殖方式对于滨湖湿地生境具有更好的生态适应性. 图2 表3 参11
Abstract:
Abstract The spatial distribution pattern and dynamics of four species of dominant plants Hippuris vulgaris,Eleocharis valleculosa,Blysmus sinocompressus and Suaeda glauca in wetlands of the Qinghai Lake were studied by means of spatial distribution analyses. The result showed that the clustering degrees of the populations of Hippuris vulgaris,Eleocharis valleculosa and Blysmus sinocompressu increased first and then decreased from the invasive stage, settle ment stage to culminative developmental stage. While the clustering degree of the population of Suaeda glauca increased from seedlings to propagation in which the population appeared aggregation. It suggested that the reproductive pattern of the former three kinds of the clonal plants had the better ecological adaptability in the wetland. Fig 2, Tab 3, Ref 11
