Study On Native Tree Species In Hefei

The resources of native tree species are rich in Hefei, but lack some relevant researches, at present there are no systemic research achievements about germplasm resources of native tree species, so it can either provide a strong basis for City Green Land System Species Planning or for the development, utilization and research of the native tree species in Hefei. Using relevant theories and methods of plant community subject, plant taxonomy and botany, through the survey of the natural forest communities, the afforestation plants around the village, the river, the road and the house, and urban garden tree species, combining the analysis of the species distribution area in Anhui which recorded in Anhui flora, we get the directory of the native tree species'germplasm resources. The main results shown as follows:1. There are 69 native tree species(including variations) belonging to 34 families and 58 genuses of natural secondary forest in Hefei, including 1 of gymnosperm and 68 of angiosperm; in which there are 30 arbors, 27 shrubs and 12 woody climbers, respectively occupying the total species of 43.5%, 39.1%, 17.4%; furthermore there are evergreen tree 5 species, semi-evergreen tree 1 species and deciduous tree 63 species; evergreen arbor 1 species, deciduous arbor 26 species; evergreen sub-arbor 1 species, deciduous sub-arbor 2 species; evergreen shrub 1 species, deciduous shrub 26 species; evergreen vine 2 species, semi-evergreen vine 1 species, deciduous vine 9 species.2.

In Hefei there are 222 native tree species(including variations) belonging to 49 families and 112 genuses in the past but not exist now, including 1 of gymnosperm and 221 of angiosperm; in which there are 85 arbors, 98 shrubs and 39 woody climbers, respectively occupying the total species of 38.3%, 44.1%, 17.6%; furthermore there are evergreen tree 25 species, semi-evergreen tree 9 species and deciduous tree 188 species; evergreen arbor 13 species, deciduous arbor 45 species; deciduous sub-arbor 27 species; evergreen shrub 6 species, semi-evergreen shrub 7 species, deciduous shrub 85 species; evergreen vine 6 species, semi-evergreen vine 2 species, deciduous vine 31 species.5.
