| Abstract: | Based on the relative membership degree and function, the model of multi-classification fuzzy pattern recognition is applied in assessment of geoenvironment quality, which counteracts the defects of maximum membership degree law and makes it easier to calculate the relative membership degree and function. The paper has established assessment model of geoenvironment quality and uses it to assess the geoenvironment quality of Lueyang county in Shaanxi. The result indicates that the method is rational and practical. |
