摘　　要：根据2012年10月份福州市主城四个区的盗窃犯罪案事件数据,利用标准差椭圆、最近邻层次聚类、核密度估算等方法,分别研究了福州市犯罪的总体集聚与发展方向、犯罪相对集聚和重点区域、以及犯罪的空间连续变化和集聚中心,并对每种方法进行了适合性评价和比较分析.结果显示:福州市盗窃犯罪案的平均中心位于台江区的茶亭街道附近;犯罪的总体集聚区域位于鼓楼区、台江区西部和仓山区北部;犯罪集聚中心为台江区的中亭街、祥坂村和晋安区的福州火车站.Based on the data of theft crime event from four main districts of Fuzhou City in October 2012, this paper respectively studied the direction of crime gathering and development , relative con-centration and key areas of crime , space continuously changing and cluster center in Fuzhou City with a series of methods such as standard deviation ellipse , nearest neighbor hierarchical clustering and kernel density estimation method ,meanwhile , we had a suitability evaluation and comparative analysis for each method .The result shows that the average center of theft crime events is nearby Chating street of Taijiang district;The overall gathering areas of crime are located in the Drum -Building district , the west of Taijiang district , and the north of Cangshan district;Crime gathering centers are located in Zhongting Street and Xiangban Village in Taijiang district , Fuzhou railway station in Jingan district .
