滑坡、泥石流等地质灾害受多种因素的影响，地质灾害预报警报工程体系的建立需要多部门、多学科的合作。2003年6月1日中国气象局和国土资源部联合启动了全国地质灾害气象预警业务，取得了很好的社会和经济效益。分析了我国滑坡泥石流等地质灾害的时空分布特点及其与降雨等多因素、多学科的关系。介绍了国家级地质灾害预报警报业务系统的有关技术，并分析了存在的问题，结合国内外的技术发展现状和趋势，提出了从地球系统5大圈层相互作用的角度研究地质灾害，建立多学科多部门合作的地质灾害监测、预报、警报和防治体系等建议。

Sediment-related disasters are caused by various factors. A multi-discipline and multi-department cooperation is important to construct the warning engineering system on sediment-related disasters. Most of the sediment-related disasters are induced by rainfall. Based on the regressive relationship between the disaster occurrence and rainfall, a meteorological-statistical potential forecast model for sediment-related disasters is developed as part of a joint project undertaken by China Meteorological Administration (CMA) and Ministry of Land and Resource ( MLR). The forecast has been launched into operation since June 1，2003，when a nationwide sediment-related disasters warning system via public media was set up by CMA and MLR. In this paper the forecast and warning system is reviewed and some valuable suggestions are presented.
