出材率表简易编制方法研究——以浙江省开化林场人工林为例

摘要

利用浙江省开化林场杉木(Cunninghamia lanceolata)人工林的标准地和树干解析数据,建立带/去皮胸径预估模型:D去=-0.152+0.939D,一致性削度方程:d2/D2 =1.113-1.435×(h/H)+0.329×(h/H)2,编制了出材率表,精度检验结果满足要求.为森林经营单位提供了一种相对简单、实用的出材率表及其编制技术.%The converted equation between DBH outside bark and DBH inside bark:D去 = -0. 152 + 0. 939D and the taper equation: d2/D2 = 1. 113- 1. 435 × (h/H) + 0. 329 × (h/H)2 were established by using the standard plots and stem analysis data of Cunninghamia lanceolota in Kaihua Forest Farm, Zhejiang Province China. Accordinyly, timber-produced rate tables were constructed. Tests of adaptability were made, and the results were satisfactory the request. The model proveded a relatively simple and practical method to forest management unit for construction of timber-produced rate tables.
