摘要
以１９８０—１９９８年近２０年间的共３１８２次水害数据为基础进行统计分析，对中国铁路水害的自然环境致灾因子作了分类，验证了其与太阳黑子之间的相关性．同时，对降水致灾的发生频数与断道时间之间的关系进行了探讨，指出地形、地质对铁路水害的影响具有区域性特征。
Based on statistical analysis of railway flood disasters with amount of 3182 times in nearly past 20 years from 1980 to 1998. the natural environmental factors on railway flood disaster are classified and its dependence on sunspots is verified. The paper investigates relationship between precipitation - induced disaster frequency and interrupted transportation time and points out that the effect of topography and geology on railway flood disaster has regional characters.
