特殊的地质结构、自然条件和地理环境使日本崩塌、滑坡和泥石流灾害十分严重,因此,日本非常重视对滑坡泥石流的监测和预报研究,并已处于世界领先地位。笔者主要对日本在泥石流、滑坡、崩塌的监测、预测、预报方面的研究及最新的成果进行总结,以期为我国开展这些方面的工作提供借鉴。 Due to the special geological structure, natural conditions and geographical environment that have caused the landslides and mudslides in Japan, the damage caused by the landslides and mudslides is very serious. Therefore, Japan attaches great importance to the monitoring and forecasting of landslide debris flows and is already a world leader. The author mainly summarizes the research and the latest achievements of Japan in monitoring, forecasting and forecasting debris flows, landslides and collapses so as to provide reference for our country to carry out these tasks.
