| 摘 要： | 区域滑坡危险性评价是进行区域滑坡风险性研究的基础.由于滑坡演变机制的复杂性,使得目前基于独立分析各因素对滑坡影响的“白箱”型评价模式具有一定风险性,同时这类评价方法要求对滑坡演变和研究区地质地理背景进行非常细致的监测和调查.为了克服这些问题,文章提出了一种基于Kriging插值理论的“黑箱”型评价方法.在利用该方法对历史滑坡点的规模进行评价的基础上,利用Kriging插值法获取研究区的滑坡危险性区划,并以四川省苍溪县为例,验证了运用该方法进行区域滑坡危险性评价的可行性.

| Abstract: | The assessment of regional geological hazards is the basis of the study landslide hazard.The research results can provide foundation for planning of land and resources,selection of important project sites,governance,monitoring and forecast of geological disasters,development of contingency measures for disaster,and environmental protection.Because of the complexity of the slidelide mechanism,the current "White Box" assessment mode which is based on independent analysis of the factors on the impact of landslides own certain risk at the same time,and this type of evaluation approaches requires a very detailed monitoring and investigation for the landslide evolution and the geological and geographical background of the study area.In this paper a "black box" type evaluation approach is proposed based on the Kriging interpolation theory.The landslide hazard zonation of the study area can be obtained by applying the Kriging to interpolating the scale of the historical landsides.Taking the Cangxi County of Sichuan Province as an example,the feasibility of Kriging interpolation theory in regional landslide hazard assessment is verified. |
