摘　　要：分析反映土壤腐蚀性的土壤理化指标。基于实验数据,评价埋地钢质燃气管道腐蚀率、孔蚀深度与土壤理化指标(p H值、电阻率、含水率、含盐量、硫酸盐还原菌含量)以及土壤理化指标自身之间的相关性。The soil physicochemical indexes which reflect the soil corrosivity are analyzed. The correlations of corrosion rate and pitting corrosion depth of buried gas steel pipelines to soil physicochemical indexes （ pH, resistivity, moisture content, salinity and SRB） as well as among the soil physicochemical indexes are evaluated based on the experimental data.

关 键 词：埋地钢质燃气管道 腐蚀 土壤理化指标 相关性分析
