摘要
对滇中地区昆明市海口林场过火3年的蓝桉林和华山松林迹地及未过火的对照林的群落进行调查分析,研究不同更新方式的植被特征。结果表明,华山松林抗火能力最差,迹地上无幼苗生存,仅有大量的草灌植物;蓝桉抗火干扰能力及萌生能力较强;过火后未伐除过火木的蓝桉林中小铁子为优势种,并且较为集中,其重要值高达99.84%;Shannon-Wiener指数和Simpson指数在各样地上的反映趋势基本一致,物种多样性指数最低的为未伐除过火木的过火蓝桉林,最高的为过火华山松林。
Based on an investigation of E.globulus Lab and P.armandi counmunity in burned area of Haikou Forest Farm , Central Area of Yunnan , and compared with control , research on the vegetation characteristics in different regeneration methods has been carried out .The results showed that the fire re-sistance ability of P.armandi forest was poor , little seedling was survival but large grass and shrub in burned area;Fire resistance ability and sprouting ability of E.globulus were strong, M.africana was the dominant species after the fire , and was relatively concentrated , the important value was up to 99.84%.Reflect trend of Shannon-Wiener index and Simpson index in different sample plots were unani-mous, the species diversity index of E.globulus non cutting wood after fire was lowest , but was highest in P.armandi forest burned area .
