摘　　要：模糊数学是一种研究和处理模糊现象的定量化分析方法,在各个领域具有广泛的应用价值。以GIS技术为基础,阐述了该方法在土壤肥力综合评价中的应用。以安庆市土壤样点数据为例,建立包括土壤的pH值、有机质、全氮等8项指标土壤肥力多指标评价模型,对安庆市范围的土壤肥力状况进行评价,分析土壤肥力空间分布。结果表明,模糊数学方法在土壤肥力综合指标评价中具有简便可行性。As a quantitative analysis method of fuzzy phenomena,fuzzy mathematics was widly applicated in many fields.By means of GIS,the method was elucidated in the comprehensive evaluation soil fertility.Taking the sample points data in Anqing City for example,soil fertility multi-index evaluation model was founded including eight indexes like soil organic matter,total nitrogen,pH value and so on,to evaluate the comprehensive level and space distribution of the soil in Anqing City.The conclusion showed that fuzzy mathematics method was simple and feasible in multi-index evaluation of the soil fertlilty.
