基于点模式的盗窃犯罪空间分布规律分析 ——以福州市主城区为例

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.

Spatial distribution of crime is one of the main research contents of Crime Geography. 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 concentration and key areas of crime, space continuously changing and cluster center in Fuzhou 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.
