Time-space crime analysis began in1829, has experienced a series of development, the foundation, research and development, application and commercialization, the client application. As an auxiliary tool for police officers, it provides strong support on crime prevention, action effectiveness evaluation, exchanges of views between each level of the platform of police, and criminal theory test. From the perspective of spatial analysis of crime can intuitively reflect the distribution characteristics, trend, and facilitating understanding the relationship between time, spatial and surrounding things. Crime analysis of spatial development bringing together a large number of interdisciplinary scholars, and formed a relatively mature algorithms and processes, and continuously explore innovative method.At present, there are some problems in our country’s crime spatial analysis, lay too much stress on spatial analysis but not on temporal analysis, and on macroscopical phenomenon not on microcosmic phenomenon, In view of the above,this paper selects a city in Jiangsu Province as a study area. The research datas are robbery (Rob and plunder), Burglary and electric bicycle theft cases from2009October to2011August., this paper mainly discusses four issues:(1) Summarized a set of complete spatial-temporal crime hot spot identification process, from the perspective of time and spatial for popular identify method and analysis respectively, identifies three categories of cases the respective distribution of hotspots.(2) Focus on the sensitive areas inside the hot spots. Aiming at hot spots to discuss distance relation between shopping malls, schools, other sensitive places and crime cases. The actual results show that cases of various types of hot spots were identified and displayed the distribution clearly. Different cases show different correlation in the same sensitive places.(3) Reason analysis of crime hot spots. Then by means of the social environment and economic data such as population, area, per capita GDP, employment rate, the number of hospitals and schools, research the causes of hot spots from the perspective of relationship between man and society environment. Prove the cause of crime is the main population, area and per capita GDP.(4) Predicting hotspots throuth the distribution of the cases. this paper predicts crime hotspots to prevention crime. And the outcome of prediction case is more correspond with practice.So that the entire process of research is rigorous and feasibility, enriches the construction of police geographical information system case study our country.
