摘　　要：采用不同方法不同抽样强度测定两个小班的蓄积量，结果表明：用多套小样圆测定小班蓄积具有高精度高工效的特点，用其测量林分平均胸径、平均树高和平均密度等具有同样效果，能够满足森林资产评估的精度要求。Different ways and sampling intensities were applied to measure the stock of two subcompartments. The results show that high precision and efficiency can be reached with multiset smallroundplot and average breast height diameter, average height and average density of crop can be measured with this method. The measurement results meet the requirement of forest assets evaluation.
