酒鬼酒生态功能保护区典型样地植物群落特征

摘要

从3个分别为400 m2样地的调查资料对酒鬼酒生态功能保护区植物群落特征进行分析，结果表明：（1）保护区植物群落种类组成丰富，各样地乔木共有22种、灌木24种、草本34种，其中1号样地有乔木15种、灌木13种、草本16种。2号样地中共有乔木 4种、灌木9种，草本13种。3号样地有乔木10种、灌木11种、草本8种。（2）各样地植物群落结构可分为乔木层、灌木层和草本层，乔木层平均高度为7.81 m，主要包括樟叶槭、板栗和猴樟等。灌木层平均高度为1.43 m，典型的有华南十大功劳、箬竹和紫金牛等。草本层平均高度为0.38 m，主要有麦冬、蝴蝶花和鸭儿芹等。（3）保护区各样地植物群落的 Shannon-Wiener 指数和 Pielou 均匀度指数变化均较大，Shannon-Wiener 指数 H 大小依次为样地2＞样地3＞样地1，Pielou 均匀度指数 J 依次为样地2＞样地3＞样地1。%Based on survey data of three 400 m2 sample plots from Jiugui Spirit Ecological Function Preservation Area in Jishao city of Hunan province, the plant community characters of the preservation area were analyzed. The results show that(1)The plant community species composition is rich, there totally were 22 species of arbor, which belong to 18 families and 21 genera, in which there were 15 species of arbors, 13 species of shrubs and 16 species of herbages in sample No,1, 4 species of arbors, 9 species of shrubs and 13 species of herbages in sample NO.2, 10 species of arbors, 11 species of shrubs and 8 species of herbages in sample No.3.(2) Community structure can be divided into arbor layer, shrub layer and herbage layer in preservation area, the average height of arbor layer was 7.81 meters, mainly including Acer cinnamomifolium, Castanea mollissima and Cinnamomum bodinieri, etc.; the average height of shrub layer was 1.43 meters, the typical shrub species were such as Mahonia japonica, Indocalamus tessellatus and Ardisia japonica, etc; the average height of herbage layer was 0.38 meters, the main herbage species were Ophiopogon japonicus, Iris japonica and Cryptotaenia japonica,etc..(3)The change ranges of plant community’s Shannon-Wiener index and Pielou evenness index were larger, Shannon-Wiener index(H) ranked from big to small as follows: sample No.2 > sample No.3 > sample No.1, Pielou Uniformity Index (J) ranked from big to small: Sample No.2 > sample No.3 > sample No.1.
