Ornamental Plant Resources and Their Diversity in Shihu Nature Reserve

Based on 3 years' observation,the ornamental plants in Shihu Nature Reserve were studied for the first time.Some 360 species of ornamental plants belonging to 229 genera and 86 families,which accounted for 61.22%,70.25% and 88.66% of the total species,genera and families of plant resources there,were reported.There were 12 species of endangered plant species under provincial protection of Jilin,accounted for 8.61% of the total.From the viewpoint of ornamental character,most of them were ornamental plants of flower,fruit and foliage plants,which accounted for 61.67%,26.94% and 21.67%.From the viewpoint of landscape use,ground cover plant,landscape tree,flower shrub occupied the majority,which accounted for 27.22%,14.44% and 11.11% of the total ornamental plants.About 97.98% of the ornamental plants distributed in the Korean pine-conifer-broadleaved mixed forests with elevation of 700～1 000 m.45.99% of the species belonged to the plant type of north temperate zone.The dominant families were Rosaceae,Ranunculaceae,Liliaceae,Saxifragaceae,Compositae.Some suggestions on conservation and development of the ornamental plants were put forward.
