摘要
通过分析群发地质灾害的主要致灾因子,可为地质灾害防治提供依据.对某山地公园内地形地貌、地层岩性、地质构造、地下水与地表水、植被、人类活动和大气降水等因素进行分析,统计得到各致灾因子和地质灾害分布的关系,进而确定地面坡度、土层厚度、地表径流流线、道路和大气降水是公园内的主要致灾因子.对基础性致灾因子的相关性分析表明各致灾因子均对公园内地质灾害的发生有较大的影响.在致灾因子分析的基础上提出针对性的防治措施建议.
Abstract
The control measures can be provided based on analyzed the main factors inducing group geological disasters.Through the analysis of the factors such as topography,stratum lithology,geological structure,groundwater and surface water,vegetation,human activities and precipitation,the paper was obtained the relationship between the disaster-inducing factors and the distribution of geological hazards in the park.Then the main disaster-inducing factors in the park were determined,which were slope,soil layer thickness,surface runoff flow line,road and precipitation.The correlation analysis of basic disaster-inducing factors shows that each factor has a greater impact on the occurrence of geological hazards in the park.Based on the analysis of disaster-inducing factors,the paper puts forward the corresponding control measures.
