| 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。

| Abstract: | 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. |
