以渭干河-库车河绿洲地区典型样区为研究对象,电磁感应仪EM38检测与田间采样相结合,针对其存在的土壤盐渍障碍问题,分析土壤电导率的剖面分布特征,建立磁感应表现电导率与土壤电导率之间的回归模型,并对运用电磁感应仪EM38划分土壤盐渍剖面类型进行探讨。结果表明:研究区表层土壤盐分具有较强的表聚性与变异强度,土壤电导率与磁感表观电导率呈极显著的相关关系,EMh对浅层土壤电导率的解译精度较高,而EMv对深层土壤电导率的解译精度要高于EMh。利用电磁感应仪EM38对研究区进行土壤盐渍剖面类型划分,表聚型与底聚型是研究区最主要的盐渍剖面类型。该结果对研究土壤盐渍化的发生机制、预测与评估该地区土壤盐渍化的发生发展具有重要参考意义。 Taking the typical area of ​​Weigan-Kuqahe oasis area as the research object, the electromagnetic induction EM38 detection was combined with the field sampling. According to its existing problem of soil salinization, the profile of soil conductivity was analyzed and the magnetic induction performance was established Conductivity and soil conductivity between the regression model, and the use of electromagnetic induction EM38 division of soil salinity profile types are discussed. The results showed that the surface soil salinity had strong surface aggregation and variation intensity, the soil conductivity was significantly related to the apparent conductivity of magnetic induction, and the interpretation accuracy of soil electrical conductivity by EMh was high. The accuracy of EMv interpretation of deep soil conductivity is higher than that of EMh. The type of soil salinity profile was classified by EM38, which was the most important type of salinity profile in the study area. The results have important reference significance for studying the mechanism of soil salinization, forecasting and assessing the occurrence and development of soil salinization in this area.
