摘要

文章通过3个地州4县(区)森林资源调查数据的分析,比较系统抽样、分层抽样等群抽样3种抽样方法在总体蓄积量调查中的运用,比较哪种抽样方法在资源分布差异较大的县域抽样精度更高,更适用、更高效。根据实测数据,在山地、坝子交错分布,资源分布不均的县(区),分层抽样法是精度最高、操作可行、节约成本的抽样方法。
        Through the analysis of inventory data for forest of four counties(districts) in three prefec?tures, by comparing the application of three sampling methods of systematic sampling, stratified sam?pling and cluster sampling in overall stand volume investigation, this paper discusses which sam?pling method is more accurate, applicable, and efficient in county area with large resource distribu?tion differences. According to the measured data, the stratified sampling method is the most accu?rate, feasible and cost-saving in mountain-plains interlacing area and in counties(districts) with un?even resource distribution.
