Because there are so many influencing factors of urban safety, and the evaluation of the information is fuzzy, this paper introduced the key risk factors for AHP Analytical Hierarchy Process to establish the urban safety assessment model; set up the urban safety factor as the target level indicator. Based on the hierarchy of the various factors of the urban safety, this paper established 9 indicators of the rule layer and 52 program layer single indexs; fixed urban safety evaluation index system of multi- level indicators system; using the matlab software, calculated the index weight of the indicators, built up the urban security method based on AHP analysis model, in o
