土壤磁性的应用研究进展

Advancement in Applied Research on Soil Magnetism

和土壤磁性作为环境变化指示体,具有诸多易于观察的特征和可以统计测量的属性。本文简述了土壤磁性常用的参数、来源(自然、生物、人为因素);参考最新文献,重点介绍了土壤磁性在土壤污染、土壤侵蚀、水体污染、大气污染等方面的应用进展:针对多学科相互交叉领域的问题进行讨论:①生态学与环境科学相结合,探索不同生态系统、生态交错带土壤磁性的空间格局;②通过分析不同时空尺度土壤磁性特征,探索物质组分及其相互转化规律、作用机制及环境内涵:③结合"3S"与常规地球物理化学分析,建立区域磁数据库,快速简便评价生态环境质量。

Soil magnetism, as an indicator of environmental change, is characterized by a number of attributes, such as easy observation, measurability for statistics, etc. A brief introduction was given to common parameters and sources of soil magnetism （natural, biological and anthropogenic contributions）, and recent advances in the study on application of soil magnetism to measuring soil pollution, soil erosion, water pollution and atmosphere pollution. Discussion was conducted on some related inter-disciplinary issues, such as 1 ） study of spatial distribution of soil magnetism in various ecosystems and ecotones through integrating eco}ogy with environmental sciences; 2） exploration of composition of matters and their inter-transformation rule, interaction mechanism as well as environmental meanings, through analyzing soil magnetism of different matters on various scales; and 3） establishment of regional soil magnetism databases for quick and convenient evaluation of eco-environmental quality by integrating 3S with conventional geo-physic-chemistry methods.
