Abstract:

The aim was to describe the current foreign study of biomass model and to summarize the developing trend and heated topic of biomass model study. The developing process of foreign study on biomass is concluded and the heated biomass model is analyzed on the basis of plenty of foreign thesis. This thesis gives a conclusion on the broadly applied heated biomass equations such as empirical equation, allometric equation, generalized allometric equation, fractal geometry, channel model etc. This thesis also concludes the current study situation of biomass calculation parameters, biomass allocation etc. According to the developing trend of biomass study, the biomass study will broaden the research spectrum and depth and the research will center on the perspectives on the survival and sustainable development on human beings. According to the foreign experience, the biomass study in China should focus on the enlargement of biomass research spectrum, standardization of parameters and conversion of dimension etc. The research of biomass should hold the right orientation and technology to give scientific conclusion.
