我省1 977年建立以省为总体的森林资源连续清查体系后,于1983年进行了第一次复查。在复查中、把按分层双重抽样估测全省森林资源改为按系统抽样估测全省森林资源。通过复查,发现样地完全复位困难,复位分布不均习,样木复位率低等问题,给动态计算分析带来一定麻烦;同时感到因精度要求提高,外业工作量仍然相当大,要在较短的时间内统一完成,在技术力量不足的情况下确有不少问题。本文以几套样本的实际计算结果,就系
After the establishment of a continual inventory system of the province’s forest resources by province in 1977, our province conducted its first review in 1983. In the review, the stratified double sampling was used to estimate the province’s forest resources instead to estimate the province’s forest resources by systematic sampling. Through the review, it was found that the problems of complete resetting of plots, uneven distribution of resetting and low reset rate of sample wood brought some troubles to the dynamic calculation and analysis. At the same time, the workload of the field was still quite large due to the increase of precision requirements. In a short period of time to complete a unified, in the case of lack of technical strength, there are indeed many problems. In this paper, the actual calculation of several sets of samples, on the Department
