This paper attempts to use the land use map, road map, community demographic data, and the 10 years data about urban crimes in a county-level city, to conduct a spatial analysis of the county town’s crimes of different types in different years. The research on the urban crime and the spatial pattern of its influencing factors shows that (1) the number of cases in the core area of the county town is the largest, followed by the east and west areas, while fringe areas have a relatively small number of cases; (2) the spatial distribution of crime density have clear regional characteristics, of which the Shuikou Road, Cross Street and Yuanshan market have the highest density of crime; the east and west areas as well as the new city in the north area are the high density areas of crime; while, the fringe of the city is the lowest density area of crime. The study has shown that urban crime has relations with the development of urban built-up area, and there is a strong linear relationship between urban crime and urban travel. Based on the establishment of the spatial distribution model of urban crime, we can simulate and predict the future spatial distribution of urban crimes, so that police departments can take accurate and timely preventive measures.
