基于地统计学的土壤养分空间变异研究进展

A review on spatial variability of soil nutrients based on geostatistics

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 high spatial variability because of the combined effects of natural and anthropogenic factors. The research methods on spatial variability of soil nutrients start with traditional statistics and advance to geostatistics and new aided technology, with geostatistics as the most commonly used method at present. This paper discussed about the fundamentals of geostatistics and its applications in spatial variability study of soil nutrients. The status and achievement based on geostatistics at home and abroad were introduced, and the existing problems and the development trends were summarized.
