长江上游滑坡、泥石流预警系统减灾效益与经验

长江上游有大小滑坡１５ 万处，泥石流沟１ 万余条。自１９９０ 年建立滑坡、泥石流预警系统以来，预警站（ 点） 与群测群防结合，成功预报滑坡、泥石流灾害险情７６ 处，处理灾害险情３４ 处，避免直接经济损失７ ０００ 余万元，走出了一条动态普查—宣传培训—重点监测—定点定人—预警预报—防灾减灾的群测群防成功之路，积累和总结了一系列成功经验和监测预报方法。

Disaster Alleviation Experience and Effect of Prediction System for Landslide and Debris Flow in the Upper Yangtze River

There are 150 000 landslides of various scales and 10 000 debris flow gullies in the upper Yangtze River. Since the landslide and debris prediction system was established in 1990, 76 landslide and debris flow has been successfully forecasted and 34 has been solved through combination of predicting points with overall measurement and prevention, which resulted in averting direct economic loss of 70 million Yuan. This is leading to a successful way of people participation in measurement and prevention as: dynamic investigation—propaganda and training—fixed site and responsible person—prediction—disaster prevention and alleviation, and a lot of experiences are accumulated and summed up and monitoring and predicting methods developed.
