The comparison of the Bayesian method with the classical methods in modeling crown width for Prince Rupprecht larch in northern China
Autor: Liang Hong, Mengxi Wang, Linyan Feng, Guangshuang Duan, Liyong Fu, Xiyue Wang
Publikováno v: Frontiers in Forests and Global Change, Vol 7 (2024)
IntroductionCrown width (CW) is a significant variable of tree growth, but measuring crown width is laborious and time-consuming. Diameter at breast height (D) is a commonly used growth variable in crown width prediction. Here, a CW-D model was devel

Prediction of tree crown width in natural mixed forests using deep learning algorithm
Autor: Yangping Qin, Biyun Wu, Xiangdong Lei, Linyan Feng
Publikováno v: Forest Ecosystems, Vol 10, Iss , Pp 100109- (2023)
Crown width (CW) is one of the most important tree metrics, but obtaining CW data is laborious and time-consuming, particularly in natural forests. The Deep Learning (DL) algorithm has been proposed as an alternative to traditional regression, but it
