摘要
现阶段我国创建生态园林城市的绿化指标都属于二维指标,这些指标不能反映绿化空间结构和绿地功能水平,尤其是在系统统计分析园林绿化的生态效益方面,很难给予准确的测算。绿量是绿化的三维指标,可以弥补二维指标的不足,能在创建生态园林城市中发挥重要作用,使城市绿化朝着提高环境效益、提高生态功能的方向健康发展。
The quantitative indicators of green land cover in the development of ecological Landscape cities in China are all two- dimensional, which can not characterize the spatial structure of urban vegetation and their ecological functions. The two-dimensional indicators are especially deficient in quantifying the ecological benefits systematically for urban green space development. ＇Green quantity＇ is a three-dimensional indicator for urban vegetation cover that can overcome the shortcomings of the two-dimensional indicators. The application of Green quantity approach can lead the development of urban green space to the directions of improving urban ecological and environmental quality.
