摘　　要：小班是森林资源规划设计调查的基本单元,其勾绘精度决定了森林空间分布定位的准确性和面积调查精度,过往对此缺乏深入的研究.为此以QuickB ird高空间分辨率卫星遥感图像为基础,对以1∶10 000地形图为手图的小班勾绘精度进行检验.结果表明,63个小班的面积平均误差25.0%,中心位置平均位移77.1 m,边界平均位移9.3 m,小班边界平均最大位移26.0 m.此外,还讨论了提高小班勾绘精度的技术方法.The subcompartment is the basic unite of forest resources inventory, its division accuracy decides the positioning veracity of forest distribution and accuracy of area surveying, so far very little research has been done on it. In this paper, the hi-resolution satellite imagery was utilized to examined the precision of subcompartment division based on the relief map of the scale of 1：10 000. The result indicated that of all 63 subcompartment was involved in the examine, the area average error was 25.0%, the center displacement was 77. 1 m, the average borderline displacement was 9. 3 m, and the average maximal borderline displacement was 26. 0 m. The technical method to improve the subcompartment division accuracy was also discussed in the paper.
