断层是滑坡发育的影响因素之一。选择雅安市雨城区和区域内232处滑坡作为研究的基础资料,通过地理信息系统空间分析技术及作者提出的滑坡影响因子贡献率的方法,得到了研究区内断层100m和200m缓冲区对滑坡的贡献率,定量研究了断层对研究区域滑坡发育的关系。研究结果表明,研究区域断层对滑坡敏感性不大,100m断层缓冲区较200m断层缓冲区贡献率值较大,为下一步研究区域滑坡危险度区划奠定了基础,同时为区域防灾提供了科学依据。
Fault is one of the influencing factors of landslide development. This paper chooses Yucheng District in Ya’an City and 232 landslides in the area as the basic data of the study. Through the spatial analysis technology of GIS and the contribution rate of the landslide impact factors proposed by the authors, the influence of the 100m and 200m buffer zones in the study area on the landslide Contribution rate, quantitatively studied the relationship between fault and landslide development in the study area. The results show that the study area has little sensitivity to landslides, and the contribution rate of the 100m fault buffer is larger than that of the 200m fault buffer, which lays the foundation for the further study of regional landslide risk zoning and provides a scientific basis for regional disaster prevention in accordance with.
