摘　　要：分析了城市绿化的形式与现状,讨论了一种新的生态型绿化模式———城市森林.并对城市绿化的乔-灌-草结构型与城市草坪型进行比较,认为前者在生态环境效益方面有较大优越性.从景观角度分析城市森林带来的效益,建议城市绿化要考虑生态服务效能及其养护管理和节约用费.It is proposed that a new pattern of forestation, arbor-shrub-lawn composite construction, based on analyzing the form and the actual state of the urban forestation. The arbor-shrub-lawn is superior by comparing with the urban lawn as for ecological environmental function including landscape. It is suggested that forestation's ecological saving efficiency and management,maintaining and reducing cost should be thought over simultaneously.

关 键 词：景观效能 城市绿化 森林式绿化 生态服务效益
