柳杉人工林林分生长模型的研究

利用标准地材料建立柳杉人工林林分生长模型并提出预估方法。当森林经理调查获得小班各林分因子后,应用本文研制的林分生长模型及相应的预估方法,可对无人为干预的柳杉人工林的蓄积量、断面积、优势高、平均高、平均胸径、株数等因子进行连续预估,为及时有效地更新柳杉人工林的小班资源数据并掌握其资源动态变化提供了一种切实可行的技术方法。

Growth model of the Cryptomeria fortunei plantation stand

Based on the data of sample plots,the growth model of the Cryptromeria fortunei plantation stand was discussed and(estimation) method was put forward.With the each stand factors from the sub-compartment by forestry management investigation,the factors of C.fortunei plantation from no human disturbance such as growing stock of sub-compartment,basal area,dominant height,average height,average breast diameter as well as numbers of individuals were estimated by using the growth model and estimation methods.The results provided feasible methods for effectively updating the C.fortunei plantation sub-compartment resources in time and controlling the dynamic variation of the C.fortunei plantation resources.
