In order to study the measurement method of urban forest tridimensional green biomass(TGB) and its ratio of precision with true color aerial photo and ARC/GIS,using a method of "estimating tridimensional volume by tridemensional volume",the TGB of urban forests of Shenyang in August 2001 was measured.

Study on three-dimensional vegetation quantity measurement and calculation of urban greening in semi-arid region based on RS and GIS——Taking anning district of Lanzhou as an example;

The "crown diameter-crown height" correlation equations and the formulas of three-dimensional vegetation quantity of tree crown are established.

"Three-dimensional vegetation quantity" was proposed as a new mentality and theory in the research of urban green space and its indices.
