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/H2),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 Cunningharnia 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.
