摘　　要：　应用多级模糊模式识别模型进行地质环境质量评价,克服了最大隶属度原则所不适用的地方,而且以相对隶属度、隶属函数为基础理论,使隶属度、隶属函数的计算更容易。建立环境质量评价模型,并应用于陕西省略阳县地质环境质量综合评价中,应用结果表明,该方法合理、可行。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.
