针对林业系统的多样性和地学特征,将多主题抽样与GIS技术相结合,从林业统计调查制度体系建设、方法体系设计、运行体系设计三方面对林业统计调查体系的建设进行了探讨;提出了在建立健全“林业系统一套表”制度的前提下,遵循单级汇总、统一公布等原则,采用“三明治”空间抽样模型、Kriging方法,分别对样本总体和未调查对象进行统计推断,设计了基于GIS技术以及多主题抽样理论的林业统计调查体系。
In view of the diversity of forestry system and the characteristics of geography, the multi-subject sampling is combined with GIS technology, and the construction of forestry statistical survey system is discussed from three aspects: system construction of forestry survey system, design of method system and design of operation system; Under the premise of establishing and perfecting a set of system of forestry system, following the principles of single-level aggregation and unified publication, the “Sandwich” spatial sampling model and the Kriging method were used to conduct statistics on the sample population and the un-surveyed population respectively Extrapolated, designed based on GIS technology and multi-thematic sampling theory of forestry statistical survey system.
