The Application of Catastrophe Progression Method and GIS Technology to the Safety Evaluation of Human Settlements

Abstract:

The safety of urban human settlements has ever aroused extensive attention of the whole world. And the safety of urban human settlements and the evaluation are scarcely studied. The safety evaluation index system of urban human settlements was put forward, the safety evaluation model based on the catastrophe theory and GIS technology was built up. And the model was applied in the case study of cities in Sichuan Province. According to the above index and catastrophe progression method, the scoring and ranking of every 17 indicators of the safety evaluation in 18 prefecture-level cities in Sichuan Province were calculated. Finally, the grading map of the safety evaluation of Human Settlements in Sichuan Province was obtained. The results showed that the evaluation result is basically accordant with people's perceptions. According to concrete conditions of different cities, it should make corresponding measures and analyze deeply to get the scientific and feasible scheme.
