Research Status and Prospect of 3D Green Biomass Measures of Urban Forest

摘要

Three-dimension green biomass refers to the volume formed by stems and leaves of a plant. It overcomes the limitation of two-dimension indices, and more accurately reflects the rationality of the plant spatial constitution and the level of ecological benefit. This paper summarizes the research advances on TGB, expatiates its concept, introduces main calculate methods of TGB, and puts forward some key problems and the view on research direction of TGB measurement. The research of TGB measurement not only is important for the establishment of a city's green database, but also provides an important index for the evaluation of urban green area. Therefore, it is useful for studying of the green environmental benefit.
