土壤养分具有高度空间变异性,这是由自然因素和人为因素共同作用的结果。土壤养分空间变异性研究方法经历了由传统统计学到地统计学再到新型辅助技术的不断改进过程,目前最常用的方法是地统计学。论述了地统计学基本原理及地统计学在土壤养分空间变异研究中的应用,介绍了国内外基于地统计学研究的现状与成果,并分析了当前研究所存在的问题和发展趋势。
Soil nutrients have a high degree of spatial variability, a result of both natural and human factors. The research methods of spatial variability of soil nutrients has undergone continuous improvement from traditional statistics to geostatistics to new assistive technologies. The most commonly used method at present is geostatistics. This paper discusses the application of the basic principles of geostatistics and geostatistics in the study of spatial variability of soil nutrients, introduces the current situation and achievements based on geostatistics at home and abroad, and analyzes the existing problems and trends in current research.
