| 摘 要： | 本文报道了松嫩平原区域土壤中8种重金属元素的背景值的获得方法及其数值范围。对松嫩平原区域内不同的土壤类型、土壤的垂直深度、土壤成土母质、土壤属性等与土壤背景值的关系进行了相关分析。研究结果表明,松嫩平原区域土壤中,8种重金属元素中绝大多数土壤背景值与土壤有机质含量有极好的正相关,而与土壤总碱度呈贞相关。

| Abstract: | Soil environmental background values are the basic data for environmental studies. They are important for setting environmental standard, evaluating environmental quality and forecasting agricultural environment. The background values of Sheavy metallic elements on Songnen plain were collected and the correlation analysis made according to soil types, vertical depths, parent materials and properties. It was pointed out that most of the background values of the 8 heavy metallic elements were correlated positively with organic matter content but correlated negatively with the total alkalinity on Songnen plain. |
