垦复抚育对油茶林下植被的结构组成及多样性影响研究

摘要

选择上年垦复抚育、前2年垦复抚育和10年未曾垦复抚育的3块油茶(Camellia oleifera)林地,分别进行林下植被的调查,结果表明,油茶林下植被以盐肤木、楤木等木本植物和芒萁、蕨、荩草等草本植物为优势,并且木质藤蔓植物相当丰富,从维护植物多样性角度出发,油茶林地垦复抚育以3年1次为好,同时建议在垦复抚育时适当保留隔药柃、狗脊蕨等常绿阔叶林下较常见的物种,以增加油茶群落的植物多样性和群落结构的稳定性.%Three spots of Camellia oleifera forest reclamated last year, two years ago and not reclamated for 10 years, respectively, were selected to investigate vegetation under the forests. The results showed, Rhus chinensis, Aralia chinensis, Dicranopteris pedata, Pteridium aquillium var. Latiusculum and Arthraxon hispidus were dominant species in the vegetation under the forests, and species of woody vine was rich. It is good that C. Oleifera forest is reclamated once every three years.
