摘　　要：以霍山七里峪随机选择的落叶阔叶林、油松针叶林边缘为研究对象进行对比分析。主要用样方法对4个落叶阔叶林和2个油松针叶林的边缘进行了调查,总共设置了192个5 m×5 m落叶阔叶林样方和72个5×5 h绿素含量进行测定发现:各物种叶绿素含量沿边缘表现出边缘-10～10 m区域>边缘10 m内>边缘-10 m外区域。The latifoliate and taiga was searched. The plot was setted upright the forest edge. The plant community survey, environment factors and the daily dynamic of photosynthesis of Corylus eterophylla Fiseh. ex Bess. was mensurated. The result showed that：The grass layer is as the same as the shrub layer. In latifoliate, the number of species, the species diversity of shrub, the species diversity of grass have the same change trend. The Chlorophy II mensuration about several plant that distribute abroad show that： The Chlorophy II content of the plant is different depend on the distance from the edge. The Chlorophy II content of the plant in the district that the distance from the edge shorter than l0 m is much than the distance from the edge longer than 10m in forest. The Chlorophy II content of the plant in the district that the distance from the edge longer than 10m in forest is much than the distance from the edge longer than 10 m out forest.
