The rotation factor method presented in this paper is a novel method based on park-transformation, suitable for machine-network transient analysis of power systems.

Based on the observation data obtained from 69 sampling sites of different age class forests, and by using biomass expansion factor function, the regression equations of stand biomass and volume of the main forest types in Pearl River Delta were built, and the regional forest biomass and its dynamics were estimated on the basis of forest inventory data.

The forest carbon stock of 31 provinces in China was obtained by the method of biomass expansion factor(BEF) based on the last six forest inventory data from 1973 to 2003.
