摘要： 通过实验区的采样数据,利用典型的经验公式计算出各采样点的合理施肥量及相应的土壤肥力指数,并用GIS方法绘制成变量施肥图和土壤肥力分布图,结果表明：田块内部土壤肥力是有差异的,不同区域的施肥量是不同的.

Abstract: By the data sampled from wusi farm ,input of fertilizer and the degree of the soil index of fertilizer are calculated using the empirical formula . At the same time,the variable input map of fertilizer and the fertilizer map are maped using GIS. The result shows:There exits difference with the fertilizer whin the field and the input of fertilizer is different too.

Key words: model, soil index of fertilizer, GIS, variable input of fertilizer, model, soil index of fertilizer, GIS
