摘　　要： 系统地论述了林分蓄积量调查的线截抽样原理和方法、并在针叶林和阔叶林中进行了验证。结果表明．其抽样精度高．调查效率和抽样效率均超过样地法。 The principle and method of line intersect sampling for surveying stand volume were introduced in this paper. and tested in coniferous forests and broad-leaved forests. The results indicate that the sampling precision of line intersect sampling is high. and the sampling efficiency as well as surveying efficiency are all higher than that of plot investigation.
