Abstract: The community structure of Rosa praelucens were studied by using the sample plot method .The results show that：(1) There were 97 vascular plant species in the community belonging to 24 families and 71 genera. And, there were 6 fern plants species belonging to 2 families and 5 genera, gymnosperms have 1 species belong to 1 family. There were 90 species of angiosperm plants belonging to 65 genera and 21 families. (2) The community structure was complicated which could be deviled into tree layer, shrub layer, herb layer, and less interstater plants. Herb layer grew better than tree layer and shrub layer. According to Raunchier, the high bud plant has high percent of 39.56% in all plants.

摘要： 采用样方调查法，对中甸刺玫(Rosa praelucens)的群落特征进行分析。结果表明：(1)中甸刺玫群落中共有维管植物24科71属97种，其中，蕨类植物2科5属6种，裸子植物1科1属1种，被子植物21科65属90种；(2)群落垂直结构可分为乔木层、灌木层、草本层。乔木层及灌木层不发达，草本层较发达。根据Raunchier生活型谱划分，高位芽植物占优势（39.56%）。
