摘　　要：根据近期对三条管线（输油、输气、输水）沿线土壤埋片试验结果，研究了土壤腐蚀性，并将沿线环境划分为三种腐蚀性等级。用土壤pH值、土壤含碳酸氢根离子量、土壤含钠离子量这三个关键参数建立了所研究的三条管道沿线土壤腐蚀等级预测回归方程，根据此回归方程来定量评价和预测三条管道沿线土壤腐蚀等级，结果表明可靠性在90％以上。Through studying along 3 pipeline's soil corrosion factor by using soil's pH value etc three key parameters, soil corrosion grade forecast regression equation is set up. According to the above regression equation to appreciate and forecast along three pipelines soil's corrosion grade, its reliability is above 90%. Because the three pipelines studied run through most part soil types in Daqing oilfield,so the regression equation can be used to appreciate and forecast soil corrosion grade of other part of Daqing oilfield.
