Data accuracy and reliability are key factors for inventory results to objectively and factually reflect forest resource situations.Sampling scheme design,inventory technology and methodology,operational process and many other factors influences the continuous forest inventory(CFI) data accuracy and reliability.Among them,sampling scheme design is the key factor of effecting CFI data quality.In order to optimize CFI system,and prevent the side effects to CFI data quality by periodical alterations of systematic sampling and special artificial treatment issues,Zhejiang Province started experiments and researches on anti-deviation technology adopting sampling scheme of permanent plots plus substitute(temporary) plots in 1994.This paper calculates and analyzes three periods of Zhejiang Province CFI data since 1989 by groups,using methods of the Difference Test for Population Average and the Variance Analysis.Every combination of the three periods of data passes the Difference Test for Population Average and the Single Factor Variance Analysis,and there are no noticeable differences.Tentative experimental results demonstrate that the CFI sample plots are well representative of Zhejiang forest resources,and obvious systematic deviation does not exist.[Ch,3 fig.9 tab.13 ref.]

数据的准确性和可靠性是清查成果能否客观、真实地反映森林资源状况的关键要素。森林资源连续清查数据的准确性和可靠性受到抽样方案设计、调查技术方法和实施操作过程等诸多因素的影响。其中,抽样方案设计是影响森林资源调查数据质量的关键因素。为了优化森林资源连续清查体系,防止系统抽样周期性变动和人为特殊对待等问题对清查成果质量的影响,从1994年开始,浙江省采用固定样地加部分替换样地(临时样地)的抽样设计方案进行防偏技术试验和研究。采用总体平均数的差异性检验和方差分析等方法,对浙江省自1989年以来的3期调查数据进行分组统计分析,3期调查数据的3组样本两两之间均通过了总体平均数差异显著性检验和单因素方差分析,无显著差异。初步试验结果表明,浙江省森林资源连续清查总体样本具有较好的代表性,不存在明显的系统偏差。图3表9参13
