摘　　要：本文将化学计量学方法引入土壤肥料研究。以一组紫色花生土理化性状数据作为样本,用因子分析法研究了土壤理化性状关系,用人工神经元网络的BP算法研究土壤理化性状与供肥能力的关系,所得结果表明化学计量学完全可以成为土壤肥料研究的强有力工具。The article introduces the chemometrics methods into the research of soil fertilizer. Using a set of physico-chemical properties data of purple peanut soil as samples, employing the factor analysis method to reseach the relations of soil physico-chemical properties, and applying BP neural network algorithm to research the relations between soil physico - chemical properties and the capcity of providing fertilizer. We are able to draw the conclusion that the chemometrics can serves as a powerful tool of the soil fertilizer research.
