Floristic Characteristics and Plant Compositions of Guangxi State-owned Gaofeng Forest Farm
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 ele-ments 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 1 385 species of vascular plants in Guangxi State-owned Gaofeng Forest Farm,belonging to 784 genera and 192 families,among which there were 85 spe-cies of ferns belonging to 49 genera and 29 families,18 species of gymnosperms belonging to 10 genera and 7 families as well as 1 282 species of angiosperms belonging to 725 genera and 156 families.There were 913 spe-cies of wild plants belonging to 540 genera and 161 families as well as 472 species of cultivated plants belong-ing 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 pan-tropical 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 ge-nus compositions were mainly tropical-subtropical characteristic.
