摘　　要：从真实犯罪案例数据出发,以湖南省新宁县为实验区,提出了一种警务岗亭优化选址方法。首先利用核密度估计划定高频案发区;然后利用区域覆盖模型,结合点距离计算方法,对主城区进行犯罪预测,并对构造的犯罪预测区进行置信度检核,置信度为84%。考虑到学校、医院等具有重大安全隐患的公共场所,针对划定的高频案发区、犯罪预测区,利用缓冲区分析、叠置分析方法构建最终优化选址区,解决警务岗亭优化选址问题。Based on the real crime case data,we presented a police post optimization location method in Xinning County,Hunan Province.Firstly,we used kernel density estimation to define the area of high frequency cases.Then we used area overlap model and point distance calculation meth-od for crime prediction in the main urban area and checked prediction area confidence.The confidence is 84%.Considering public places such as schools and hospitals with major security risks,we used the buffer zone analysis and superimposed analysis methods to construct the final opti-mized location area for delineated high-frequency incident and crime prediction areas,which solved the police post optimization location problem.
