摘要

传统的盐碱土壤分类及含量的划分方法是通过对采样点土壤样品化验统计值来确定。因工作量大和费用高，通常不能对研究对象进行连续、系统的了解。提出了研究地质雷达信息与土壤含盐量、pH值、有机质含量、含水量等参数的相关关系及探测与检测技术方法。理论研究表明，土壤的物理和化学特性变化差异可以使探测的雷达波振幅及波形、频谱特性等波的几何学与动力学特点产生响应。研究结果显示这种方法是一种直观快速的可行方法，可为今后生态环境治理因素评价和遥感资料的解译提供地面探测的雷达电磁波频谱与确定不同颜色土壤单元所对应的盐碱土壤含盐量、pH值、有机质含量、含水量的依据。

Abstract

The conventional identification of salinizated soil is based on the laboratory results of soil specimen. It can not be applied continuously to the investigating area inch by inch due to high cost and heavy work of dense sampling rate. However

the correlation among Ground Penetration Radar(GPR) information and soil salinity

pH value

organism and water content enable us to formulate a method with which parameters above specified may be investigated. Theoretical study show that the existence of variations in soil chemical and physical properties results in correlated response in geometry and dynamics in GPR waveforms and their amplitude. The field experiment indicates that GPR method would be a feasible technique with fast speed for evaluation of environmental properties of soil salinization.
