摘要
受自然环境因子(如地形地貌、地层岩性、地质构造等)和诱发因素(如降雨、地震等)的影响,滑坡在空间上的分布特征极其复杂,但其空间分布仍具有内在的规律。本文以"汶川地震"极端事件为时间分段点,采用基于样方的点模式分析法对汶川地震重灾区滑坡的空间分布特征进行了分析,得出滑坡点群在震前和震后均呈空间聚集模式分布。这说明由于受各环境因子及其因子组合作用,汶川地震重灾区滑坡的发生无论在震前还是震后并非随机事件,其滑坡点的空间分布具有统计意义上的自相似结构,且无特征尺度。
By the impact of the natural environmental factors(such as topography,stratum lithology,geological structure,etc.) and the inducing factors(such as rainfall,earthquakes,etc.),the characteristics of the landslides distribution in space are extremely complex,however,its spatial distribution still has internal rules. This paper takes the time of "Wenchuan earthquake"extreme event as the time phasing point,quadrat-based point pattern analysis of landslide point space distribution indicates that the landslide point group showes a spatial agglomeration model before and after the earthquake. This results demonstrate that the occurrence of landslide in the study area are not random events before and after the earthquake,but the results of the natural environmental factors,or factors combination; and the landslide point spatial distribution of Wenchuan earthquake heavy disaster area has selfsimilar structure in statistical sence,no characteristic scale.
