摘　　要：通过航空电磁法在松辽地区的实测结果与已知的水文地质成果对比分析,说明航空电磁法在土壤盐渍化程度及范围圈定、地下水水质划分、土壤颗粒度划分、盐渍化趋势预测等区域农业生态地质调查中的作用。展示了航空电磁法廉价高效的特点。Based on a comparison between the achievements made by the airborne electromagnetic method in Song-Liao region and the available hydrogeological data, this paper explains the role played by the airborne electromagnetic method in such regional agricultural eco-geological investigations as the determination of soil salification limits and extent, the division of underground water quality, the classification of soil grain sizes and the prediction of salification trend. It is shown that the airborne electromagnetic method is characterized by low cost and high efficiency.
