| 摘 要： | 河流泥沙灾害有河道，水库淤积、土地沙化、湖泊、城市或建筑物淤积及工程设施被冲刷破坏等表现形式。中国是河流泥沙灾害最严重的国家，每年河流泥沙造成的损失在100亿元量级，其中因河道泥沙淤积造成的损失约20亿元，土地沙化损失在10亿元左右，河流泥沙造成的其它灾害也很严重。

| Abstract: | Riverine sediment hazard includes silting up rivers and reservoirs, burying lakes, cities and buildings and washing out engineering facilities, as well as the land desertisation. China's riverine sediment hazard is most serious in the world. Annular loss due to riverine sediment hazard is in level of 10 billion RMB in which the loss from silting up of rivers is about one billion RMB and that from land desertisation is about two billion RMB. Other disasters induced by riverine sediment is serious as well. |
