摘　　要：为给林场植物资源的保护、开发和利用提供参考,采用线路调查和样方调查相结合的方法,对广西壮族自治区国有高峰林场维管植物科、属、种组成和生活型及本土野生植物区系地理成分进行分析。结果表明,广西国有高峰林场维管植物共有1385种,隶属于192科784属,其中蕨类植物29科49属85种,裸子植物7科10属18种,被子植物156科725属1282种。野生植物161科540属913种,栽培植物119科327属472种。以草本植物为主(558种),藤本植物最少(181种)。寡种科和单种科及寡种属和单种属占比均较高。外来入侵植物共有65种。在本土野生植物区系地理成分中,科的泛热带和热带类型占比为52.53%,属的泛热带和热带类型占比为72.86%,且属的R/T值较高,表明广西国有高峰林场具有较强的热带-亚热带性质。广西国有高峰林场有8种国家二级重点保护野生植物和5种广西重点保护野生植物。广西国有高峰林场植物种类丰富,植物区系地理成分复杂,科和属组成以热带-亚热带性质为主。In order to provide references for protection,development and utilization of plant resources in forest farms,compositions of families,genera,species and life forms of vascular plants,and floristic geographic elements of native wild plants in Guangxi State-owned Gaofeng Forest Farm were analyzed by combination of line investigation and sample survey.Results showed that there were 1385 species of vascular plants in Guangxi State-owned Gaofeng Forest Farm,belonging to 784 genera and 192 families,among which there were 85 species of ferns belonging to 49 genera and 29 families,18 species of gymnosperms belonging to 10 genera and 7 families as well as 1282 species of angiosperms belonging to 725 genera and 156 families.There were 913 species of wild plants belonging to 540 genera and 161 families as well as 472 species of cultivated plants belonging to 327 genera and 119 families.Herb plants(558 species)were dominated and vine plants(181 species)were the least.Proportions of depauperate and mono families and depauperate and mono genera were higher.Number of invasive species was 65.In floristic geographic elements of native wild plants,proportions of pantropical and tropical types of families were 52.53%,proportions of pantropical and tropical types of genera were 72.86%,and R/T value of genera was higher,which indicated that Guangxi State-owned Gaofeng Forest Farm had stronger tropical-subtropical characteristic.There were 8 second-level national key protected wild plants,and 5 Guangxi key protected wild plants in Guangxi State-owned Gaofeng Forest Farm.Guangxi State-owned Gaofeng Forest Farm was rich in plant species with complex plant floristic geographic elements.Family and genus compositions were mainly tropical-subtropical characteristic.
