An effective method for developing a set of tree biomass models and their application in regional forest biomass inventory is presented by using the sample data of Chinese fir, Masson pine, and broad leaved tree species.

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.

In connection with the situation of forest resource inventory in China, some suggestions are presented.

The computer data processing technology is applied to the county level forest resource inventory,which provides a scientific,simple and accurate method for the procassing of complicated data,and thus has improred the efficiency of interior working of the forestry resource inventory.

Based on the forest inventory conducted in 2003 in the DaxingAnling Forest Region, this paper presents an analysis on the dramatic increase in forest mortality and puts forward some countermeasures as for how to reduce it.

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.

According to the characteristics of the regional forest resources,this paper discusses the rules, structure and methods on the construction of an evaluation index system of regional forest resources sustainable development based on the sustainable development theory.

At last,the paper discussed the relevant system behaviors of regional forest resources,includ.

An overall framework of DSSMRFR (DSS for Macro Decision of Regional Forest Resources) is designed in accordance with analysis of main decision problems on regional forest resources.
