摘　　要：通过对昆明市近郊的长虫山和元宝山林区具有代表性的4片不同龄级的华山松人工林进行了调查,并对不同林龄的华山松人工林的群落结构、物种组成,林下植物生活型、生长型进行了分析。研究结果表明,随着林龄的增长,华山松人工林郁闭度及华山松的株数呈现递减趋势,林下植物的科属种数呈现不同程度的增长趋势,但物种多样性仍然低下,50年龄的华山松人工林分的物种多样性仍然显著低于当地的天然林分;林下植物生长型以灌草为主,其中灌木的重要值随林龄的增长而有所增加,林分结构随林龄增长而趋向稳定。Through the survey data from 4 representative plots of artificial Pinus armandii forest of different ages in Kunming City,we analyzed the community structure,species constitution,life form and development form of the tree and the under-canopy plants.It showed that as the forest age increased,the closure rate and individual number of Pinus armandii decreased,while the genera and species number of the under-canopy plants increased with different extents.Nevertheless,the bio-diversity in artificial Pinus armandii forest was significantly lower than the natural ones.The under-canopy plants were mainly shrubs.As the ages of the forests increased,the importance value of shrubs increased and tended to be stable.
