Abstract:
Standardized and time normalized data of the latest two or more forest resource inventory plots in the provinces were achieved to obtain the sample data of the forest resources plots and samples in the target year,and a nationwide database of 2005,2012 and 2014 sample plots and trees were established.It provides effective ground data support for China's forest resource dynamic analysis,forest resource monitoring,forest volume and biomass modeling.
Key words: inventory of forest resources, standardization, time normalization
