中文摘要	通过对榆林卧云山植物园绿化树种的实地调查,分析了乔木、灌木树种的组成结构。结果表明,榆林卧云山植物园现有乔木16科31属46种,其中本地树种与引进树种之比为1∶1.42,常绿树种与落叶树种之比为1∶3.18;灌木14科19属21种,其中本地树种与引进树种之比为1∶2.5,常绿树种与落叶树种之比为1∶9;乔灌木数量之比为1.06∶1,国家级保护乔灌木树种9种。表明卧云山植物园已由沙地零星灌木草本植被转向乔木灌草结合的针阔混交林森林植被群落,为沙地与黄土高原过渡带这一特殊立地条件下建立植物园及珍稀濒危植物迁地保护提供了参考。
英文摘要	A field investigation was carried out on the trees and shrubs occurring in Yulin Woyunshan Botanical Garden.The compositional structures of the trees and the shrubs in the garden were analyzed.Totally 46tree species,(belonging to 16families and 31genera),21shrub species(belonging to 14families and 19genera)were observed.The proportion between native and exotic tree species was 1∶1.42;it was 1∶3.18between evergreen and deciduous tree species.For shrubs,the proportion between native and exotic species was 1∶2.5;it was 1:9between evergreen and deciduous species.The proportion between the number of trees and shrubs was 1.06∶1.Nine tree and shrub species were under state-rank protection.The investigation indicated that this area had been changed from shrub-grass vegetation to the arbor-shrubgrass compound land.The results would provide references for establishing botanical gardens and ex-site conservation of rare and endangered plants in desert-loess transitional zone.
