文章利用地理信息系统（Geographic Information System，GIS）方法，以綦江县为例，利用1990年~2010年间綦江县地质灾害普查的累积数据，结合数字高程模型（Digital Elevation Model，DEM）、地形因子和地层发育年代，初步分析了綦江县地质灾害时空分异。结果表明，綦江县地质灾害的发生发展在时间上具有明显的季节性，在空间分布上显示出不均匀，但有相对集中的特性，在切割强烈、坡陡、相对高差大的中低山区发生频率较高，地形起伏较少，岩性较坚硬的低山地区发生平率较低。%This paper, taking Qijiang County as an example, uses the cumulative data of 1990~2010 geological disasters, DEM, topographic factors and strata in the preliminary analysis of the spatial and temporal variation of geological disasters in Qijiang county by using GIS method. The results show that the development has obvious seasonal time occurrence of geological disasters in Qijiang County, in the spatial distribution showed uneven, but concentrate relatively, has a high frequency in cutting strong, steep slope, relative elevation of the low mountain, the terrain is less, lithology is hard and low mountain areas occurred flat rate is low.
