摘要
在分析影响地质灾害活动因素的基础上,构建了地质灾害易发性评价指标体系,介绍了隶属函数的建立方法及模糊支持向量机(FSVM)模型的建立过程,最后运用该模型对周宁县地质灾害易发性程度进行评价,把周宁县地质灾害易发性程度划分为地质灾害高易发区、中易发区、低易发区和不易发区四个级别,结果表明该方法可行,具有较强的实用性。
By analyzing the factors which influence on the geological disaster,an index system for evaluating its probability was built up.Fuzzy membership function building methods and fuzzy support vector machine modeling process were introduced.The approach was applied to assess geologic disaster probability in Zhouning County.The results showed that the levels of geologic disaster probability was catalogued into four classes: high easy-happening area,medium easy-happening area,low easy-happening area and not happening area.It indicating that the approach was feasible and very practical.
