“This study analyzed the impact of climatic and topographic factors on tree radial growth of red pine and oak forest in Korea. Annual tree growth can be affected by age, current size, density, competition, site environment, and climatic factors such as temperature, precipitation and humidity. To find the relationship between annual tree radial growth and climatic factors, we took core samples from individual trees and measured the tree radial width. We found the spatial differences in tree radial growth. There exists spatial relationship between topographic and climatic factors, and tree radial growth. Using this relationship, we predicted spatial distribution change of red pine and oak forest with GAM (Generalized Additive Model) analysis based on GIS.”
