模糊聚类分析法在声环境功能区划分中的应用

基于聚类分析和模糊数学的基本原理，运用模糊聚类分析的方法在南通市声环境功能区调整中对难以确定功能区的部分单元进行模糊聚类分析。通过分类，将具有共性的单元划归一类。结果表明，类别的划分突出了特性，反映了不同类别功能区的差异，对难以确定功能类别的单元归属起了科学、客观的辅助作用。

Application of Fuzzy Clustering Analysis in Division of Acoustic Environmental Function

Based on the fundamental theory of clustering analysis and fuzzy mathematics,some units whose function categories diffi-cult to be confirmed were analyzed during the adjustment of acoustic environmental function zones in Nantong.The similar units which have the same characters were grouped.Such division can show that different clusters have their own characters and the differ-ences among these functions.The analysis can help to divide those units whose attributions were difficult to be determined into the suitable functional categories.
