| 摘 要： | 自助法和刀切法是在小样本条件下对总体进行估计的非参数统计方法.本文除介绍其基本原理外,主要是阐述其在小样本条件下估算胸径、冠幅、材积、树高。根径等森林调查因子和可行性.从结果看,利用这两种方法估算有关森林调查因子是令人满意的,精度都在83％以上.

| Abstract: | Bootstrap and Jackknife are statistical methods of non-parameter under the condition of small - samples on the estimated population. This paper gives an introduction of Bootstrap and Jackknife,and estimates some forest factors of investigation-breast diameter,crown diameter,volume,tree heightandstump diameter,etc. under the condition mainly. Besides,the basic principles areintroduced.The results show that the methods are satisfactory to estimate someforest factors of investigation. Both of the precisions are over 83 per cent. |
