【摘要】 对石家庄市城市林业应用的绿化植物与群落结构进行了调查,分析了植物资源数量、常用植物与使用频率、不同绿化景观的物种丰富度与植被多样性特征、乔木树种的年龄结构等.认为石家庄市现有绿化植物的资源总量偏少,常用植物过于集中,除公园与城郊风景区外各类型绿地景观的物种丰富度与多样性指数较低,乔木树种的年龄反映出现有林业发展水平距城市森林目标差距较大.建议加大引种与驯化力度,增加植物的使用频率,大力开发乡土植物资源,注重植被结构的自然性与塑造城市林业的地方特色.更多还原

【Abstract】 The applied frequency,biodiversity and richness of species,and community structure of urban forests in Shijiazhuang city have been investigated.The results showed that the shortage of species resource,inadequate biodiversity and richness in all kinds of grassland except garden and suburb forests,etc.have limited the functions and development of urban forest.To meet the progress of city,some measurements should be adopted: introducing and domesticating new species,increasing applied frequency of plant,developing indigenous tree species and building specialization of local urban forest.更多还原
