城市森林三维绿量研究现状与展望

三维绿量是指所有生长植物的茎叶所占据的空间体积。城市三维绿量的测算是城市森林生态功能研究和环境效益评价的基本前提, 也是城市生态系统研究的重要内容之一。文中主要在进一步明确城市森林三维绿量概念及提出意义的基础上, 对目前三维绿量的主要测算方法进行阐述与总结, 并指出现有三维绿量测算方法中存在的主要问题, 同时对测算方法的发展趋势进行了展望。希望通过对城市森林三维绿量的研究丰富城市森林评价指标, 为城市森林生态功能和环境效益研究以及城市森林布局优化提供有价值的参考。

Research Status and Prospect of 3D Green Quantity of Urban Forest

Three-dimension green quantity refers to the spatial volume formed by stem and leaf of a plant.The measurement for three-dimension green quantity is a basis precondition for the study of ecological function and the estimation of virescence environmental benefit of urban forestry,and also is an important part for urban ecosystem study.This paper summarized the research advance on three-dimension green quantity,expatiated its concept,introduced main calculative methods of 3D green quantity,and put forward some key problems in them and the view on research direction of 3D green quantitive calculation.The research of 3D green quantity provides not only an important index for the evaluation of urban forest,but also useful references for studying of ecological function and environmental benefit of urban forest,as well as the pattern optimization of urban forest.
