| Abstract: | In the past,the stand mean diameter at breast height and stand mean tree height growth functions of Larix principis-rupprechtii Mayr were primarily based on the age of tree.This paper adds two more factors,Site Index and Afforestation Density,to the growth functions by using the Genetic Programming to simulate and get the better theoretical growth functions.New multiple growth functions are identified for Larix principis-rupprechtii Mayr growth models supplying high-accuracy and strong-applicable growth fun... |
