固定样地复查时由于样木不能复位,使复查期内总生长量及总消耗量无法正确测定。如果这类样地达一定数量时,必然降低资源动态变化的估计精度,影响连续清查的应有效果。《林业调查规划》84年6期中介绍的一种计算进界生长量及消耗量的近似
Due to the sample wood can not be reset when the sample is fixed for review, the total growth and total consumption during the review period can not be determined correctly. If such a sample reaches a certain amount, it will inevitably reduce the estimation accuracy of the dynamic changes of resources and affect the proper results of continuous inventory. “Forestry Investigation Plan” 84 years 6 period described in a calculation of the growth rate and consumption of approximation
