However, the scope of the study is limited due to the lack of fixed plot observations. With the improvement of my country's continuous forest inventory system, each continuous forest inventory can obtain the observation values of thousands of retest plots with relatively complete information and reliable quality, which is a very valuable material that is worthy of further development and utilization. The research and construction of traditional dynamic growth is based on the continuous inventory data of forest resources to carry out modeling.

The purpose of the present invention is to provide an accurate measurement method for the dynamic growth of a sub-compartment to provide accurate sub-compartment measurement annual data, and the cost is small and the cycle is short, providing a feasible method for the dynamic monitoring of forest resources.
