| 摘 要： | 本文以湖北鄂州长江外滩植被为研究对象 ,对滩地植物群落的基本特征及多样性指数相关性进行分析。结果表明 :1 .滩地乔木和灌木种类组成较少 ,均只有 2科 2种 ,前者有杨柳科的杨树 (Populusspp .)和金缕梅科的枫香 (LiquidambarformosanaHance) ,后者仅杨柳科的旱柳 (Salixmatsudanakoidz)和桑科的构树 (Broussonetiapapyrifera(L)vent) ,但是草本植物物种比较丰富 ,有 1 3科 2 5属 2 8种 ;2 .滩地草本植物群落类型较丰富 ,有 1 2个类型 ,植物群落结构开始由单一转向复杂 ;3.多样性指数Shanno -Weiner (H′)和丰富度 (R) ,多样性指数Simpson (D)和均匀度指数 (J)的相关系数分别是rH′-R =0 .95 6,rD -J =0 .979,呈极显著正相关 ;指数H′与均匀度指数J,指数D与丰富度R ,丰富度R与均匀度指数J的相关系数分别为rH′-J =0 1 90 ,rD -R =0 0 78,rR -J=0 1 0 0 ,均无显著性 (P <0 0 1 )。

| Abstract: | This study focused on the vegetation in Yangtzi River beach land along Ezhou in Hubei province. Plant community characteristic and correlation among diversity indexes were analyzed. The results were : 1). There were respectively 2 families, 2 species of tree and shrub to be found-Populus spp. and Liquidambar formosana Hance,Salix matsudana koidz and Broussonetia papyrifera (L) vent. Compared with tree and shrub, herb was richer, 13 families, 25 genera, 28 species were found on the beach land. 2). There were rich plant communities on the beach land, which were divided into 12 associations and had developing trend from unitary structure to complex and stable structure. 3). The correlation coefficient between Shanno-Weiner (H′) index and species richness (R), between Simpson index (D) and evenness index (J) respectively were 0.956, 0.979, showed very significant positive correlation, but the correlation coefficient between H′ and J, between D and R, between R and J respectively were 0.190, 0.078, 0.100, without significant correlation to be found. |
