| 摘 要： | 通过详细的野外地质灾害调查，确定了合阳县现有地质灾害隐患点80个，以黄土崩塌及黄土滑坡为主，主要沿大峪河、金水河、徐水河、太枣河4大沟系及黄河西岸展布。研究表明，本区地质灾害的发生，除了受岩土体性质、地形地镜等因素影响外，不规范的人类经济工程活动和降雨是引发地质灾害发生的一个重要因素。在对该区地质灾害发育规律进行分析的基础上，结合合阳县历史地质灾害发生时的降雨资料，做出地质灾害气象预警降雨量判据图。利用该降雨量判据图，采用模板判据法，对该区8个地质灾害易发区进行气象预警。在接到当地气象部门的气象预报舌，结合气象预警区划图，对地质灾害易发区发生地质灾害的可能性做出预报，以利于当地各部门采取适宜的防范措施。

| Abstract: | According to detailed field geo-hazard survey, there are eighty potential geo-hazards in Heyang County and they are loess rockfalls and loess landslides mainly. The geo-hazards spread along Dayuhe River, Jinshui River, Xushui River, Taizao River and Yellow River's western side. Property of rock and soil and landform affect the geo-hazards, in addition, nonstandard economic and engineering activities are the most important reasons for geo-hazards. According to history rainfall data of Heyang County, criterion map for early warning can be drawn. Based on this map, combined with weather forecast, we can forecast possibility of geo-hazard and prevent it from occurring by right measure. |
