Abstract:A in the field comprehensive evaluation method was developed. In order to attain a better result, this method integrated fuzzy mathematics together with traditional quasi quantificational field comprehensive evaluation method. This method was realized by Visual Basic programming, and ArcView GIS 3 1 was used to generate soil fertility distribution map and the evaluation result map. After comparision study, it has been shown that this evaluation method is effective and accurate.
Keywords:quasi  quantificational evaluation  comprehensive evaluation  GIS
