测定了大庆地区土壤的理化性质，用综合评价指标方法和以土壤电阻率作为单项评价指标的方法评价了土壤腐蚀性。同时，采用线性极化测试技术测量了Ａ３钢在土壤介质中的极化电阻，进而对土壤腐蚀性作出了定性评价。结果表明，用上述几种方法对土壤腐蚀性进行的评价有较好的一致性，该区土壤腐蚀性等级为中等强度。
The physical and chemical properties of soils in Daqing area were determined. The soil corrosivity was evaluated by comprehensive evaluation index method and soil resistivity as a single evaluation index. At the same time, the polarization resistance of A3 steel in soil media was measured by linear polarization test technique, and then the soil corrosion was qualitatively evaluated. The results show that there is a good consistency between the above methods and the evaluation of soil corrosivity. The soil corrosion level in this area is medium intensity.
