Abstract

Research object was middle-aged plantation of Cunninghamia Lanceolata in Huangfengqiao national forest farm, You county, Hunan Province. Ratio of crown inclination(RCI) was set up as a index to signify crown inclination in research. Ratio of crown inclination in east, west, south and north were calculated and histograms in four direction were drawn which showed that crown inclination was generally existed in research area. Principal Component Analysis (PCA) was used to measure the influence that diameter at breast height(DBH), height, height under branch and crown height had on Cunninghamia Lanceolata crown inclination. The result showed that most influential factors of the four factors was diameter at breast height(DBH) and height.
