Features: The preparation of this manual aims to provide a practical, convenient, and quick method for calculating the volume of standing timber. The compiled two-parameter volume tables for standing timber consist of two parts: one part includes fast-growing broadleaf tree species, such as poplar and Paulownia, based on local standards DB/3700866001—89 and DB37/T-92; the other part primarily includes coniferous tree species, such as black pine and Chinese pine, based on the forestry industry standard LY208—77. Additionally, for the convenience of timber utilization and commercial transactions, rapid calculation tables for raw timber volume and Chinese fir log volume have been compiled based on relevant national and industry standards. It should be noted that the accuracy of the standing timber volume tables depends on the selection of data for compilation and measurement. During use, there are certain measurement requirements and applicable ranges. The compiled two-parameter volume tables for standing timber are primarily suitable for the North China region. Other regions may require adjustments before application. This manual can serve as a reference for forestry professionals, forest farm operators, timber dealers, and farmers, among others.
