摘　　要：基于研究区植物名录和野外样方调查统计数据,采用Raunkiaer生活型分类系统,对霍山七里峪植物种类组成生活型谱进行分析。结果表明,七里峪研究区植物群落的维管植物有221种,分属157属,53科,其中蕨类植物2科2属4种,裸子植物1科2属2种,双子叶植物43科133属187种,单子叶植物7科20属28种;霍山七里峪植物生活型组成以地面芽植物为主,占41%,其次是高位芽植物,占28%,一年生植物也较多,占22%,地上芽植物和地下芽植物很少,仅占5%和4%。总体上反映了该区夏季温暖且多雨,冬季寒冷且漫长的气候特点。Based on the study area′s plants and sampling statistical data,Raunkiaer life form classification system was used on the plant species of life form spectrum analysis of Huoshan Mountain Qiliyu.The results showed that Qili valley plant communities recorded in the study area were 221 kinds of vascular plants,belonging to 157 genera,53 families,including two families,2 genera and 4 species of gymnosperms,133 genera,187 species,43 families,133 genera,187 species,of dicotyledonous plants,7 families,20 genera,monocotyledon ferns,one famity,2 genera,2 species of.The plant life form composition in Huoshan Mountain Qiliyu was mainly hemicryptophyte,which accounted for 41%,followed by phanerophyte （28%） and 22% had more annuals.Chamaephyte and geophyte were few only,which accounted for 5% and 4% respectively.Generally,the climate features of warm and rainy in summer,cold and long winter were reflected.
