福建省滑坡灾害特征及驱动因素分析

Characteristics and Driving Factors of Landslide Hazard in Fujian Province

依据福建省灾害信息网、福建省国土资源厅、福建气候公报及相关文献资料,建立福建省滑坡灾害数据库,对福建省滑坡灾害特征进行分析,得到福建省滑坡灾害群发性强、年际变化大、地区差异明显、发生频率高和强度小的特征。根据福建省滑坡灾害特征分析,采用资料分析法对滑坡灾害驱动因素进行分析,得出了对福建省滑坡灾害影响大的驱动因素为地质构造、地形坡度、降雨暴雨、地质岩性及人类地质工程活动的结论。根据各个驱动因素提出了福建省滑坡灾害防治措施,为福建省的滑坡灾害防治提供科学依据。

According to Geological Disaster Prevention Information Network, Department of Land ＆ Resources and climate bulletin of Fujian Province, this paper analyzes the characteristics of landslides in Fujian Province.The results showed： they have characteristics of severe group, large variability, obvious differences, high frequency and low intensity. According to the analysis of the characteristics of landslides, the driving factors of landslides were analyzed by adopting data analysis method. The driving forces influencing landslides in Fujian province are geological structure, topography, rainfall, geological lithology and human geological engineering activities. According to the various driving factors, measures of control were proposed, which can provide a scientific basis for the prevention of landslides in Fujian Province.
