Geohazard Susceptibili-ty Evaluation Along the Road in Hainan Tropical Rainforest National Park Based on Logistic Regression Model
摘要
Abstract
Due to the frequent geohazards along the along the road of tropical rainforest park,it is of great sig-nificance to carry out the research on the vulnerability of geological hazards for disaster prevention and reduc-tion.Taking the road in Jianfengling Park as an example,six factors including fault,slope,slope direction,water system,road and rainfall were selected as susceptibility evaluation indexes,and the influencing factors of themin the study area were quantitatively analyzed.Based on GIS platform,the sensitivity evaluation was carried out by using two models of certainty coefficient and certainty coefficient logistic regression.The re-sults show that rainfall,slope and distance of road are main controlling factors affecting the development of geological hazards.The high-prone areas are mainly located along the road with relatively developed geologi-cal hazards,and the very low and low-prone areas are located in the high-altitude areas with rare human set-tlement.The AUC values of CF model and CFLR model are 0.785 and 0.808 respectively,showing that both evaluation models are great reliable and objective.The value from certainty factor compelling logistic regres-sion model(CFLR)has higher accuracy than that of the single certainty factor model(CF).The research will pro-vide scientific basis for geological hazard assessment and disaster prevention and reduction in the study area.关键词
