| 摘要: |
| 采用鄱阳湖乐安河流域13个监测断面1995-2002年8年的污染指标的监测平均值作为原始数据,应用物元分析法对各监测断面进行优化.在确定最佳和最次理想点的基础上,建立标准物元矩阵和节域物元矩阵,并结合综合关联函数,选出优化点位.同时应用相关分析中的距离分析和K-均值聚类法确定各监测点所属类别.综合这三种优化结果,最终确定乐安河流域可以由传统的13个监测点位优化为9个监测点位. |

| Abstract: |
| The matter element analysis has been used to optimize points selection of water quality monitoring in the Lekn River basin of Lake Poyang, taking the average monitoring data in 8 years which is from 1995 to 2002 as the original data. Matter element matrix of standard and partial unit can be established on condition that optimum and second optimum points are chosen, connected with integrative and correlative function, the optimized points are chosen. Meanwhile, the distances methpd which is belonged to the correlation and the Means Cluster process are used to the classification of monitoring points. Integrating three methods above, the 13 traditional monitoring points in the Le, an River basin of Lake Poyang can be optimized to 9 monitoring sites. |
