摘要
近年来,用WCL-1型磁化率仪(北京地质仪器厂制造),测定了宁夏境内上千个上样和300余个典型剖面的土壤磁化率。研究表明,银川平原及鄂尔多斯西南丘陵土壤的磁性分布及变异同地形地貌有明显关系;六盘山山地土壤的磁性分布也具有垂直地带性。
Innrecent years, the magnetic susceptibility (MS) of the tho-usands soil samples and more than three hundred soil profiles are measured by susceptibilitimeter WCL-1 (the apparatus is made in the Geoiogical Instruments Manufactory of Beijing) .The result shows: the soil magnetic dis-triluticn and its variance are concerned with the topography or geomop hol-ogy rcmarkably in the soil of the Yinchuan plain and southwesten hills in Erdous.The soil magnetic distribution in Liupanmotnntain area,it also pos-sesses vertical region characteristics.
