| 摘 要： | 将灰色聚类法应用到湿地水体富营养化评价中，旨在建立起一套比较完善、适合于湿地水体富营养化的评价体系。把湿地水体富营养化程度划分为6个级别，其阚值参照中国湖泊富营养化评价标准和湿地富营养化的特点。利用灰类白化权函数描述水体富营养化分级界限，正确地选择了各参评指标对于各等级的聚类权，在此基础上构建了湿地水体富营养化灰色聚类法综合评判模型。并以扎龙湿地为例进行了实例计算与分析，验证了此模型的准确性、可比性和实用性。 |

| Abstract: | Grey clustering method is applied to evaluate the eutrophication of wetland water, in order to established a superior evaluation system which is suitable for wetland eutrophication evaluation. Eutrophication degree is divided into 6 classifications, and threshold of each classification makes reference to eutrophication standard of Chinese lake and eutrophication characteristics of wetland. Whitenization weight function is used to describe the limit of eutrophication classification, and clustering weight is selected correctly. Finally, based on grey theory,a mathematical model for evaluating water eutrophication of wetland is established. The application of this method to evaluate the water eutrophication in Zhalong Wetland is given as an example for demonstration, which proves clustering model is exact, comparable and applied. |
| Keywords: | grey clustering method eutrophication of wetland evaluation clustering weight |
