摘要:

国家热带雨林公园内地形陡峭,地质灾害频发,开展国家热带雨林公园地质灾害易发性评价对减少地质灾害风险具有重要意义。以海南省保亭县为研究区,选取断裂、高程变异系数、剖面曲率、NDVI指数、水系和道路作为评价因子,分别采用确定性系数模型(CF)、确定性系数与逻辑回归耦合模型(CF-LR)、确定性系数与层次分析法耦合模型(CF-AHP)对研究区进行地质灾害易发性评价与精度分析。结果显示,地形地貌对地质灾害的发育具有控制作用,地质灾害受断裂、公路和水系分布影响明显;三种模型均有较高的准确性,其中确定性系数与逻辑回归耦合模型(CF-LR)相对更高,是一种地质灾害易发性评价可靠性高的模型。

Abstract:

The national tropical forest park has steep topography and geological disasters occur frequently. It is of great significance to evaluate the vulnerability of national tropical forest park to geological disasters for risk reduction. Taking Baoting County, Hainan Province as the study area, the fault, elevation variation coefficient, profile curvature, NDVI index, water system and road were selected as evaluation factors. The deterministic coefficient model (CF), the coupling model of deterministic coefficient and logistic regression (CF-LR), and the coupling model of deterministic coefficient and analytic hierarchy process (CF-AHP) were used to evaluate the vulnerability of geological disasters and its accuracy of the study area. The result shows that the topography controls function to the development of geological disasters, and geological disasters influenced by fracture, highway and water distribution are obvious. All the three models have high accuracy (highest for CF-LR), which is a highly reliable model for the evaluation of geological hazard susceptibility.

Key words: deterministic coefficient method, logistic regression, AHP, susceptibility, geological hazard, Baoting County, Hainan Province
