| 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。

| Abstract: | 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. |
