安徽省毛竹林下植物物种多样性的研究

Understory Plant Diversity in Moso Bamboo Forests of Anhui Province

借以安徽省林业厅与浙江农林大学合作以提升安徽省竹产业的契机,调查安徽省毛竹面积最多的霍山县、广德县、黄山区三县(区)毛竹林下植物物种多样性的情况,以了解和掌握在当前的经营水平下,毛竹林下灌木与草本的数量特征、群落的物种结构特征,并且对如何开发珍稀植物物种进行了探讨。结果表明:毛竹林下灌木主要以株高小于40 cm的蓬蘽、紫金牛、山橿、六月雪、山胡椒等为主,草本主要是淡竹叶、中日金星蕨、大油芒等;群落的物种结构特征表现为灌木主要以豆科、蔷薇科、大戟科、壳斗科、樟科为主,草本主要以禾本科、菊科、金星蕨科、百合科、唇形科、豆科等为主。保护毛竹林植物物种多样性,有效利用毛竹林下空间,发展复合经营,对提升毛竹林经营效益有重要意义。

The Forestry Department of Anhui Provincial Government and Zhejiang A F University are cooperating to promote the development of bamboo industry in Anhui province.The understory plant species diversity of Moso bamboo forests in the top three Moso distributing counties,i.e.,Huoshan,Guangde and Huangshang,of Anhui province were investigated.Results showed that the dominant shrubs were composed of Rubus hirsutus,Ardisia japonica,Lindera reflexa,Trachelospermum jasminoides,Serissa japonica and Lindera glauca,while the dominant herbs included Lophatherum gracile,Parathelypteris nipponica and Spodiopogon sibiricus and so on.The community structure is characterized by the shrubs of Leguminosae sp.,Rosaceae sp.,Euphorbiaceae sp.,Fagaceae sp.and Lauraceae sp.,and herbs of Gramineae sp.,Compositae sp.,Thelypteridaceae sp.,Liliaceae sp.,Labiatae sp.and Leguminosae sp.Protection and exploration of understory plant resources are very important to the promotion of Moso bamboo plantation industry.
