摘　　要：土壤中常量元素主要呈矿物形式存在,将土壤氧化物指标转化为土壤矿物指标对于生态地球化学评价具有重要意义。阐述了利用土壤氧化物数据计算土壤矿物的原理方法,用隶属函数描述了土壤粘土矿物与农作物生长适宜性的关系,提出了以模糊逻辑系统为核心的土壤质地地球化学评价方法。实例应用表明,氧化物数据用于土壤质地评价是可行的。Major elements of soil mainly exist in the form of minerals and it is of significance to translate the oxide index into mineral index in eco-geochemical evaluation.Principle and method of the calculation of clay minerals content by oxide data are set forth in the paper and the relationship between clay minerals and suitability of crops growth is described by membership function.Geochemical evaluation method of soil texture based on fuzzy logic system is put forward.A case study indicates it is feasible to apply oxide data in evaluation of soil texture.
