摘　　要：为给研究大庆地区石油类污染物在土壤中迁移和转化规律提供背景数据 ,分析了该区地带性土壤———黑钙土和非地带性土壤———盐碱土等主要物理、化学性质 .结果表明 :黑钙土和盐碱土有机质含量均随深度增加而减少 ;盐碱土呈强碱性 ,黑钙土呈中等碱性 ;盐碱土质地黏重 ,含水率比黑钙土大 ;盐碱土电导率明显高于黑钙土 ;盐碱土黏土矿物绝对质量分数比黑钙土的高 ,黏土矿物成分均以伊利石、绿泥石为主 ,盐碱土含伊 /蒙混层 .In order to supply background data to study the migration and conversion pattern of oil pollutants in Daqing region, the paper analyzed the main physical and chemical properties of belt soil-chernozem and non\|belt soil-saline alkali soil. The results show that the organic content of chernozem and saline alkali soil decreases with the depth increases, that saline alkali soil assumes characteristic of strong alkaline, but chernozem middle alkaline. Because saline alkali soil is geo-adhesivity strong and contains more water than chernozem, it's porosity and water content are all present positive correlativity, and it's electrical conductivity is distinctly bigger than chernozem, clay mineral absolute content higher than chernozem. Clay mineral components in saline alkali soil are mainly illite and chlorite while saline alkali soil is mixed layer of illite and montmorillonite.
