摘要:

作者于2003年, 在全面调查的基础上, 选择广东、广西、江西、海南、福建、浙江等省区10个乐东拟单性木兰(Parakmeria lotungensis)分布较集中的群落, 采用每木调查法进行样方调查。结果表明: 16,900 m2的样地面积内共记录伴生植物477种, 隶属110科237属。其中, 乔木层的优势种类主要集中在壳斗科、樟科、山茶科和木兰科; 灌木层以杜鹃花科、紫金牛科、大戟科、山矾科、冬青科的种类为主; 草本层以铁芒萁(Dicranopteris linearis)、钱氏鳞始蕨(Lindsaea chienii)、狗脊蕨(Woodwardia japonica)和乌毛蕨(Blechnum orientale)等蕨类植物为主。大部分的种类仅在一个群落或少数群落中出现。乐东拟单性木兰没有固定的伴生植物。

Abstract:

Parakmeria lotungensis is a rare and endangered plant endemic to China. Based on intensive field surveys, we chose 10 plant communities where relatively more individuals of P. lotungensis were found. Based on these surveys, we developed a checklist of 477 plant species, belonging to 237 genera and 110 families. Dominant tree layer species belonged to the Fagaceae, Lauraceae, Theaceae, and Mognoliaceae plant families, whereas dominant shrub layer species belonged to the Ericaceae, Myrsinaceae, Euphorbiaceae, Symplocaceae, and Aquifoliaceae plant families. A majority of herbaceous layer species belonged to fern families, such as Dicranopteris linearis, Lindsaea chienii, Woodwardia japonica, and Blechnum orientale. We found that most species occurred in only one or relatively few communities and there are no obligate plants which associate with P. lotungensis.
