Investigation of Ornamental Tree Resources in Laba River Natural Reserve

In order to protect and rationally exploit the ornamental trees in Laba river natural reserve,the species and their visual characteristics were investigated by field investigation in the reserve.There were ornamental trees with 57 faculties,82 genus and 138 species in Laba river natural reserve,including ever-green arbor trees with 5 faculties,11 genus and 21 species,ever-green shrubs with 9 faculties,11 genus and 21 species,deciduous arbor trees with 27 faculties,36 genus and 53 species and deciduous shrubs with 16 faculties,25 genus and 43 species.According to their visual characteristics,there were tree-shape view trees with 18 faculties,26 genus and 28 species,leaf-shape view trees with 18 faculties,25 genus and 42 species,green-leaf view trees with 14 faculties,22 genus and 41 species,spring-leaf view trees with 5 faculties,6 genus and 13 species,autumn-leaf view trees with 18 faculties,28 genus and 43 species,two-colors leaf view trees with 1 faculties,1 genus and 2 species,patch-color leaf view trees with 1 faculties,1 genus and 4 species,flower view trees with 14 faculties,30 genus and 58 species,and fruit view trees with 19 faculties,28 genus and 49 species.Additionally,27 species of important values such as Davidia involucrata,Taxus chinensis,Cereidiphyllum japonicum,Magnolia sargentiana,Actinidia polygama were observed.The results provide efficient data for protection and utilization of ornamental trees in Laba river natural reserve.
