摘要
采用样方法,对湖南阳明山国家森林公园映山红群落的物种组成、结构特征以及物种多样性等群落特征进行调查与分析。结果表明:阳明山映山红群落是以映山红(Rhododendron simsii)、茶(Camellia sinensis)以及圆锥绣球(Hydrangea paniculata)为优势种的植物群落,共有植物23种,隶属于13科18属9个地理分布型,热带属略多于温带属;群落的生活型以小高位芽植物(66.38%)为主,叶级以中小型叶(95.66%)为主,叶片特征以单叶、纸质非全缘型叶为主。阳明山映山红植物群落Simpson多样性指数为0.41、Shannon-Wiener多样性指数为1.28、Pielou均匀度指数为0.40,说明阳明山映山红植物群落稳定性与均匀性较差,尚处于演替的前中期,有继续演替的趋势。
Using the method of sample plot,the Rhododendron simsii community in Yangming Mountain National Forest Park in Hunan was investigated and the community composition,the structure and species diversity were studied.The results showed that in the Rhododendron simsii community Rhododendron simsii,Camellia sinensis and Hydrangea paniculata were the dominant species.The community was composed of 23 species,belonging to 13 families 18 genuses and 9 geographical distribution types;the tropical genera were slightly more than the temperate genera;in term of life form,the microphanerophytes(66.38%)were dominant and the dominating characters of leaf were mesophyll,microphyll(95.66%),simple,coriaceous,unentire.Diversity index analysis showed that the simpson index was 0.41,Shannon-wiener index was 1.28 and pielou evenness index was 0.40,which shows that the stability and uniformity of the community are poor,it is still in the early-middle stage of succession,thereafter the succession of the community tends to continue.
