摘要
利用熵权法和属性识别理论建立浅层地下水环境质量评价模型。采用地下水质量标准作为评价依据,选取15个影响因子作为评价指标,通过建立属性空间矩阵、计算属性测,再利用信息熵确定评价指标权重,应用置信度准则对晋江市浅层地下水环境质量进行属性识别与综合评价,评价结果表明该模型能有效地解决浅层地下水质量评价问题。
Using of the entropy weight method and attribute recognition theory to build the shallow groundwater environmental quality evaluation model. The evaluation basis are used evaluation of groundwater quality, selected 15 factors as evaluation index, through the establishment of the attribute space matrix, computing the attribute measurement, and then determine the weights of evaluation indexes by using the information entro- py, the application of confidence criterion make comprehensive evaluation and the attribute recognition on the quality of environment of shallow groundwater in Jinjiang City, the evaluation results show that the model can effectively solve the the problem of shallow groundwater quality evalu- ation.
