| 摘 要： | 为了揭示蜘蛛群落在马尾松林中的地位和作用规律，于1995年4月至1996年6月对湖南新邵、长沙、岳阳3县不同立地条件马尾松林抽样调查90块样地．马尾松林蜘蛛群落计有25科62属107种．在马尾松林垂直分布的4个层次中蜘蛛群落具有明显的分层特征．灌木层的蜘蛛种类最丰富，林冠层次之．这两层蜘蛛对整个蜘蛛群落的稳定和控制害虫危害功能的发挥起决定作用，树干层和地面层蜘蛛处于过渡和补充地位．植被盖度对蜘蛛群落多样性和稳定性有显著影响，林龄的影响则不明显．

| Abstract: | In order to reveal the status and role of spider communities in Pinus messoniana forests, the authors have investigated 90 sample-plots of Pinus messoniana forests, respectively in Xinshao, Changsha, and Yueyang County of Hunan province during the timefrom April, 1995 to June, 1996. There are 25 families, 62 genera, and 107 species in thespider communities in the forests. The spider communities obviously have a level-administered characteristic. There are abundant spider species in the shrub levelF the less abundant are in the canopy level. The spiders living in these two levels play a decisive role instabilizing spider communities and controlling harmful functions of pests. The spiders living in the stem level and ground level play a transitive and complementary role. The vegetation cover rate significantly influance the diversity of spider communities, and the effectof stand-age is not evident. |
