Simulation of diameter distribution of Pinus sylvestris var. mongolica plantations on sandy soil

Abstract

Abstract: Through the use of reverse Weibull function, this article simulated the diameter distribution of Pinus sylvestris var. mongolica plantations on Zhanggutai Sandy Land, which shows that for this simulation, reverse Weibull function had the characteristics of high precision and strong adaptation. Correlation equations of three parameters of reverse Weibull function and stand age and density, and regression equation of diameter distribution and these three parameters were established, which could be used to predict the stand yield and timber grade, and to appraise the management effects.

Key words: Pinus sylvestris varmongolica, Plantation, Diameter distribution, Reverse Weibull function, water environment, transformation, fate, analytical technique, AgNP
