Research into Evaluation of Fire Risk in Urban Area Based on AHP and GIS——Taking the Nucleus of Kelamayi City for Exemple

For evaluating fire risk of urban area accurately,the nucleus of Kelamayi city was taken as the study area,and an index system of evaluation of fire risk was structured by using AHP and the grade criterion of indexes was formulated.The ranges of different grades of risk of some indexes were designated exactly by using buffer analysis and network analysis of GIS.The risk indexes were scored based on the grade criterion.At last,a picture of grades of fire risk in the study area was obtained after computing and revising evaluation results.The results show that 6 assessment units of the study area belong to the high fire risk that are 2.2% of all,and 62 assessment units of the study area belong to the middle fire risk that are 22.9% of all.
