Tree diameter at breast height growth rate model based on multiple elements and standardized growth table construction method

The invention provides a multi-element-based tree diameter at breast height growth rate model and a standardized growth table construction method, which comprehensively considers four element systems of competition, forest stand, terrain and climate, establishes a diameter at breast height growth rate model of main tree species, divides five diameter step groups of 5cm, 15cm, 25cm, 35cm and 45cm based on a tree height-diameter at breast height model, a binary wood volume model and a diameter at breast height growth rate model, and establishes a standardized growth table of the tree diameter at breast height growth rate model. The three indexes of the diameter at breast height, the tree height growth and the wood volume growth of the single tree after five years are calculated, a standardized growth table is constructed, a process for popularizing the standardized growth table to any land parcel is provided, and a more accurate and efficient solution is provided for tree growth prediction and management. 本发明提供
