摘要:
系统介绍磁性示踪技术的基本原理、测量参数、计算模型及应用前景。近年来，利用磁性示踪研究土壤侵蚀成为示踪技术在土壤侵蚀研究中应用的一种新思路，利用环境物质磁性的时空差异性来研究区域内侵蚀泥沙来源，以沉积物磁性作为流域环境变迁指示剂以及利用磁性参数的变化研究土壤侵蚀等方面已取得的一些成果，同时利用人工磁性示踪剂来研究土壤侵蚀强度的空间分异规律，定量描述侵蚀方式的演变及侵蚀过程的发生、发展规律，并在野外进行小区试验。磁性示踪技术具有测量简便易行、无破坏性、连续性好、分辨率高，并可迅速与其它示踪技术复合示踪等优点，将成为水土保持监测的有力手段之一。
Abstract:
This article systemicly introduced the basic principle, the survey parameter, the computation model and the application prospect of the magnetic tracing technique.In recent years, the magnetic tracing technique has became a new technology in the soil erosion research.With measured temporal and spatial variability of natural magnetism, sources of mobilized sediments have been assessed using different parameters.Manmade magnetic tracers were also applied in experimental plot to study the temporal and spatial variability of erosion intensities; observe the evolvement of erosion types and erosion processes.The magnetic tracing technique has a few of merits, such as simple and convenient surveys, no destructiveness, better continuity, highly power of discrimination, and may rapidly compound tracing with other tracers technique and so on.It will become one powerful method of the soil and water conservation monitoring.
