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.
