摘要
以苏宝河流域地震滑坡统计资料为依据,基于贡献权重方法对苏宝河流域地震滑坡本底因子的敏感性进行了分析。结果表明:以贡献率作为各本底因子在分级区间上的敏感性分析的指标,确定了该区域内各因子最利于地震滑坡发育的数值区间;以互权重作为地震滑坡发育各本底因子之间的敏感分析指标,确定了该区域内各本底因子对地震滑坡的贡献率大小。
Based on the statistical data of seismic landslide in Subaohe Basin,the contribution weight method was applied to perform sensitivity analysis of root factors of seismic landslide in Subaohe Basin. The results showed that the contribution rate,as the sensitivity analysis index of root factor in the grading interval,was used to determine the numerical interval of each factor that is most favorable for the development of seismic landslide. The mutual weight, as the sensitivity analysis index for root factors of seismic landslide development,was used to determine the size of the contribution rate of root factor on the development of seismic landslide in this area.
