采用标准地调查法,对深圳梧桐山毛棉杜鹃林天然更新进行调查与评价。结果显示,在毛棉杜鹃林更新能力排在前12位的树种中,更新能力良好的有浙江润楠Machilus chekiangensis、亮叶冬青Ilex viridis;天然更新等级为中等的树种有华鼠刺Itea chinensis、短序润楠Machilus breviflora、密花树Rapanea neriifolia、香叶树Lindera communis;天然更新为不良等级的树种有豺皮樟Litsea rotundifolia var. oblongifolia、鸭脚木Schefflera octophylla、光叶山矾Symplocos lancifolia、毛棉杜鹃Rhododendron moulmainense、吊钟花Enkianthus quinqueflorus、粗叶榕Ficus hirta。在6块标准地中,仅有2块标准地内发现毛棉杜鹃幼苗,所有标准地没有发现苗高<30 cm 的毛棉杜鹃幼苗,且株数密度低,属于天然更新不良的树种,不能依靠天然更新来保持其地位和观赏特性。
The regeneration characteristics of Rhododendron moulmainense forest were investigated by sample plot method. It was showed that there were 12 species with larger amount of seedlings in the understory. The results showed that the population of Machilus chekiangensis, Ilex viridis had great regeneration ability; the population of Itea chinensis, Machilus breviflora, Rapanea neriifolia, Lindera communis had medium regeneration ability; the population of Litsea rotundifolia var. oblongifolia, Schefflera octophylla, Symplocos lancifolia, Rhododendron moulmainense, Enkianthus quinqueflorus Ficus hirta had bad regeneration ability. The seedlings of Rhododendron moulmainense had only been found in two sample plots among the six sample plots, and no seedlings lower than 30 cm. Besides, Rhododendron moulmainense forest had low forest density. So the natural regeneration of Rhododendron moulmainense cannot keep its landscape sustainable.
