灰色关联法在乡村生态环境评价中的应用

在研究灰色系统理论的基础上，以福建省生态村的评估工作为例，将灰色关联分析法应用到乡村生态环境质量的综合评定中，建立以多重指标下的生态环境灰色关联模型，并进行实例应用。结果证明该方法可行，得出了实测值分别与标准值和理想值的关联度，而且可以进行同级别的比较分析。

Rural ecological environment evaluation models based on grey relational analysis

Based on the gray system theory, grey relational analysis（GRA) is applied in the evaluation of ecological environment of ecological villages in Fujian province. A multi-index grey relational analysis model for evaluating ecological environment is formulated, which is employed in practical village ecological environment evaluation. The gray relation degrees between practical values and the standard values and between the practical values and the ideal values are obtained. The results show that the GRA method is feasible in ecological environment evaluation and can be employed in the analysis of the same grade villages.
