摘　　要：农业环境损害案件类型多样且各具特点,针对耕地内含人工障碍层这类鉴定对象复杂且不确定因素较多的案件,现有鉴定技术成本投入较高、耗时较长且存在一定的技术局限性,很大程度影响司法鉴定的时效性与科学性。为探索地球物理勘探技术高密度电阻法在耕地破坏鉴定中的应用效果,本研究在天津某区实证案例现场铺设总长度为1338 m的9条测线,共682根有效电极数,探测地下人工障碍层固体垃圾的分布特点,同时采用钻探勘查方法进行验证。结果显示地下填埋固体垃圾深度在2.8~7.0 m不等,分布面积约3000 m^(2),高密度电阻法测试结果与钻探勘查方法结果接近。研究表明,高密度电阻法在司法鉴定实证案例中具有较强的应用价值,将其与钻探勘查方法结合使用有利于降低鉴定成本并提升地下人工障碍物勘查的准确性,对进一步开展鉴定工作具有重要的借鉴意义,同时为我国农业环境损害司法鉴定实证研究开拓了新的思路。Agricultural environmental damage cases are diverse and usually exhibit unique characteristics.Cases of artificial barrier layers in cultivated land are often complicated and uncertain,and the existing identification technology is costly,time-consuming,and limited by certain technical constraints,which greatly affects the timeliness and scientificity of judicial expertise.To evaluate the effectiveness of the high-density resistivity method in the identification of cultivated land destruction,nine measuring lines with a total length of 1338 m and 682 effective electrodes were laid in a case site in Tianjin.The distribution characteristics of underground solid waste were investigated,and the results of the high-density resistivity method were validated by drilling exploration.The underground landfill solid waste depth ranged from 2.8 m to 7.0 m,and the distribution area was approximately 3000 m^(2).The test results of the high-density resistance method were similar to those of the drilling exploration method.We conclude that the high-density resistance method has considerable application value for empirical cases and is recommended to be used simultaneously with the drilling method.Combined application of the highdensity resistivity and drilling methods will reduce costs,improve the accuracy of judicial appraisal,and provide new ideas for empirical research on agricultural environmental damage.
