城市森林建设的意义和途径探讨

THE SIGNIFICANCE AND APPROACHES OF URBAN FOREST CONSTRUCTION

城市森林是城市生命支持系统的主体，具有最大的生态服务功能，能提高城市国有生态资产，减少绿地养护管理费用，丰富城市景观。因此，城市森林建设是将城市可持续发展由口号变成实际行动的生态工程，也是２１世纪城市园林绿化的必由之路。城市森林建设应加强合理规划布局，遵循生态学原理，以乔木为骨架，以木本植物为主体，以生物多样性为基础，以植物群落为结构单位，以地带性植被为特征，以城乡一体化为格局。

Urban forest is the main life support ecosystem in city,which can produce the maximum eco service function,improve urban state owned eco asset and reduce the cost for the conservation and management of green land and also enhance the urban landscape.So ,the construction of urban forest is eco engineering which put the sustainable development from slogan to practical action.And a few basic principles for urban forest construction were also put forward in this paper,namely,strengthen the rational planning of urban forest distribution,obey ecological principles,and take trees as main composition and abundant biodiversity as foundation and plant community as construction unit and zonal vegetation as its fundamental characteristics.Furthermore,the urban and suburb green land ought to be merged into an organic whole.At last,the main aim of urban forest is to improve the eco effects of the green space system.
