摘要
利用weibull分布函数3个参数a,b,c的预测模型以及立地、林龄与径阶的相关模型和立地、林龄、径阶与径阶高的相关模型,给出了日本落叶松林分结构合理分布的理论参数和不同立地、各龄阶径阶分布的理论株数,为合理经营利用日本落叶松林分提供了科学的理论依据.
Using Weibull prediction model with three parameters, a, b, c and relation model of site index, stand age with diameter class, and relation model of site index, stand age, diameter class with height of diameter class, theoretical parameters of suitalbe construction distribution in Japanese larch stand, and theoretical tree number of each diameter class in different site index are indicated, which provides theoretical foundation for reasonable management of Japanese Larch.
