Research progress in monitoring and simulating stem radius growth: an overview

Traditional dendroclimatology research is based on the statistical correlation between tree-ring chronology and modern observation data, but lacks consideration of the mechanisms of tree-ring growth. In order to reconstruct past climatic conditions more reliably, the response of stem radius growth dynamics should be studied in detail. At present, in international researches, monitoring and simulation methods are generally treated as two separate approaches. The monitoring method generally consists of dendrometer measurements, micro-coring, and pinning. Here, we present the research progress of stem radius growth dynamics studies derived from these methods, and provide prospects for future study.
