| Abstract: | Forest biomass has great research and application value in forest ecological system.Conception,significance and development history of China's forest biomass were explained.Extra emphasis was placed on research contents and methods of forest biomass in China.An introduction was made on the researches including dominant species,vegetation,litter,coarse,root and regional scale biomass estimation as well.Some common forest biomass estimation methods were summarized,such as harvest,regression model,and biomass-expansion-factor equation.There still existed some shortages in forest biomass research in China,i.e.in disproportion of study field,the collection of basic data and the scaling-up of measurement.Finally,the development trend of forest biomass was pointed out. |

| Keywords: | forest biomass estimation model coarse woody debris scaling - up remote sensing inversion |
