| 摘 要： | 以新疆伊犁地区盐渍土为研究对象,通过分层采样测定土壤盐分含量,采用EM38和EM31两种磁感式大地电导率仪测定土壤表观电导率,分析不同土壤层次盐分与土壤表观电导率的相关性,应用逐步回归方法构建土壤盐分解译模型,并进行了模型精度验证。研究表明:土壤盐分含量与土壤表观电导率之间呈显著线性相关,构建的土壤盐分解译模型具有良好的精度。本研究将为精确解译伊犁地区土壤盐渍化特征提供重要的方法支撑。

| Abstract: | Taking salinized soil as research object in Ili City of Xinjiang Uygur Autonomous Region, soil salinities were measured in different layers and soil electrical conductivity were recorded by EM38 and EM31. The correlation between soil salinities and apparent soil electrical conductivities in different layers were analyzed and interpretation models of soil salinity were established. The results showed that significant liner correlation existed between soil salinities and apparent soil electrical conductivities in different layers, which indicate the high accuracy of the established models. This study can provide an important support in accurately interpreting the characteristic of soil salinity in Ili. |
