Focus on the problem of big differences in computing aspect factor of subcompartment between two methods of most eigenvalue based on DEM and scalar quantity,a new vector method for the aspect factor of subcompartment is proposed in terms of the characteristics of digital terrain analysis and the theory of vector statistics.
针对目前基于DEM的最大特征值法和标量平均法在小班坡向求算中存在误差大的问题,基于地形分析特点和矢量统计原理提出了一种计算小班坡向的矢量方法,并对比了该方法与前2种方法的实验数据计算结果,表明该方法求算的小班坡向与森林资源调查规程的要求更加吻合。
