Relationships among Growths and Canopy Factors of Dalbergia odorifera Plantations with Different Stand Densities
In order to provide theoretical basis for optimization of management measures in Dalbergia odorifera plantations, taking D. odorifera plantations as research objects, correlation analysis and path analysis methods were used to study relationships among growths and canopy factors. Results showed that with increase of stand density, DBH, crown width and crown volume of D. odorifera plantations decreased, tree height and crown length ratio showed trends of firstly increase and then decrease, and crown shape ratio increased. Correlation analysis results showed that most of growths and canopy factors were significantly or extremely significantly correlated in D. odorifera plantations with different stand densities. Path analysis results showed that direct and indirect effects of crown width, crown length ratio and crown shape ratio on tree height and DBH were more complicated. Effects of crown width on DBH and tree height were larger.
