摘要: 采用对应分析方法研究了辽河平原土壤中14种元素的地球化学分布,将其分为亲氧、亲硫、易淋溶元素3个组群.土壤类型、成土母质、土壤机械组成和有机质对元素分布有一定影响.指出了元素的地球化学性质是产生分异的内在原因,土壤机械组成中的大于0.01mm的粘粒仅对易淋溶元素分布有一定影响,0.01-0.001mm粒级的粘粒与亲硫元素、土壤有机质与亲氧元素分别呈显著正相关.

Abstract: Geochemical distribution of 14 elements in soils of Liaohe River plain and factors affecting their distribution are investigated with correspondence analysis method. The results show that these elements could be classified into three groups: oxyphilic, sulphilic and leached elements. The mentioned distribution differentiations are caused by the geochemical properties of these elements. Soil type, parent material, soil physical composition and organic matter content are the factors influencing element distribution. Clay particles with size of more than0.01mm only influences leached element distribution. Clay particles of 0.01—0.001mm and organic matter are significantly related with sulphilic and oxyphilic elements respectively.
