摘要
为了寻求出一种既可以保证土壤属性空间全覆盖又保证区域地理全覆盖的科学合理的土壤样点布设方法,基于国内外相关文献,从传统统计学和地统计学2个角度对土壤样点布设方法进行系统分类,通过对现有的土壤调查布点方法进行归纳总结,详细介绍了相关研究的主要方法及国内外发展状况,并对今后该领域的研究进行展望。通过归纳整理发现,目前相关研究中,虽涉及范围广,但众多方法中仍存在诸多问题,并没有形成一套体系能够既满足土壤地理空间全覆盖又满足土壤属性空间全覆盖;未来土壤样点调查研究应在空间及属性全覆盖进行更加系统深入的研究,逐步解决样点空间位置、代表性及密度问题。
The research aims to find out a scientific and reasonable soil sample layout method which can guarantee the full coverage of soil properties and the full coverage of regional geography by summarizing the existing methods of soil investigation.Based on the relevant literatures at home and abroad,The soil sample layout methods was systematically classified from the perspectives of traditional statistics and geostatistics.The main methods of related research and the development status at home and abroad were introduced,and the prospects for research in the field were put forward.Through inductive sorting,it was concluded that although there were a wide range of related researches,there were still many problems in many methods,and there was no system that can satisfy both the full coverage of soil geospatial space and the full coverage of soil property space.Future soil sample survey research should conduct more systematic and in-depth research on the full coverage of space and attributes,and gradually solve the problem of spatial location,representativeness and density of samples.
