Abstract

Purpose

Soil contamination is one of the most pressing environmental problems on a global scale. However, assessing the shape and size of an area where pollution occurs, and the spatial variation in the pollution level, is a complex issue. Field magnetometry is a cheap and fast tool for soil pollution assessment. The purpose of the paper is to systematically describe the history, current state, and potential future applications of geostatistical methods in field magnetometry.

Materials and methods

The article was written based on over a hundred outstanding scientific papers describing soil research around the world using field magnetometry and geostatistical methods, combined with various secondary variables such as geochemical and diffuse reflectance spectroscopy measurements of soil as well as satellite observations.

Results and discussion

Geostatistical methods allow for the optimal use of the magnetometric method in areas with different types of soils such as forests, arable fields, meadows, fallow lands, and urban areas as well as for the determination of spatial variability parameters of magnetic susceptibility. The use of geostatistical methods in field magnetometry also allows for a more accurate determination of other soil and environmental parameters significantly affecting the value of magnetic susceptibility, which must be taken into account when conducting field measurements.

Conclusions

Both geostatistics and field magnetometry are considered groundbreaking methods in pedological research but even greater results arise from the simultaneous use of these methods. The synergy effect resulting from the use of geostatistical methods in field magnetometry allowed for the achievement of many significant scientific and practical findings. Especially, the cokriging method plays an increasingly important role in magnetometric research, thanks to the integration of magnetic susceptibility measurements with other types of measurements.

在土壤磁力测量中使用地质统计方法:综述
摘要 目的 土壤污染是全球范围内最紧迫的环境问题之一。然而,评估污染区域的形状和大小以及污染程度的空间变化是一个复杂的问题。现场磁力测量是一种廉价、快速的土壤污染评估工具。本文旨在系统地介绍地质统计方法在野外磁力测量中的历史、现状和未来的潜在应用。 材料和方法 这篇文章是在百余篇优秀科学论文的基础上撰写的,这些论文介绍了世界各地利用野外磁强计和地质统计方法进行的土壤研究,并结合了各种次要变量,如土壤的地球化学和漫反射光谱测量以及卫星观测。 结果和讨论 地质统计方法可使磁测法在森林、耕地、草地、休耕地和城市等不同土壤类型的地区得到最佳应用,并确定磁感应强度的空间变化参数。在野外磁力测量中使用地质统计方法还能更准确地确定对磁感应强度值有重大影响的其他土壤和环境参数,在进行野外测量时必须考虑到这些参数。 结论 地质统计学和野外磁强计都被认为是土壤学研究的开创性方法,但同时使用这两种方法会产生更大的成果。在野外磁力测量中使用地质统计学方法所产生的协同效应使得许多重要的科学和实践成果得以实现。特别是,由于磁感应强度测量与其他类型的测量相结合,cokriging 方法在磁测量研究中发挥着越来越重要的作用。 图表摘要

期刊介绍: The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
