山地灾害研究的发展态势与任务

泥石流、滑坡等山地灾害已成为世界各国十分关注的自然灾害问题。据最近几年的国际学术会议,泥石流、滑坡研究的前沿领域是：泥石流、滑坡活动的地带性与全球气候变化的规律；泥石流、滑坡起动机理、动力学模型；泥石流、滑坡等山地灾害风险分析、发生时间预报；成灾机理与减灾防灾关键技术。国内研究较晚,但发展很快。经过近50 a的研究,涉及上述诸多研究颁域。但研究不深,还存在不少差距。据国内外研究态势,针对山地所实际,提出了在泥石流、滑坡理论创新和防治关键技术等研究方面12条任务。

The Development Trend of the Mountain Hazards Research and the Task

Debris flows and landslides are the serious environments hazards which bring the attention of world peo- ple. According to the new achievements of the national academic conference recently,the research frontiers of deb- ris flows and landslides can be concluded into the follows aspects:debris flows,landslides and the globe climate change;the mechanism of debris flows and landslides initiation;the dynamical model of debris flows and land- slides;forecast and assessment of debris flows and landslides hazard and risk;the mechanisms and the controlling technology of debris flows and landslides. The research in our country is later and not deep than the abroad and there are some differences,but there is a fast progress on the above aspects in recent 50 years. Based on the cur- rent situation and developments of debris flows and landslides study at home and abroad,the paper bring forward 12 tasks for us on the research of theories innovation and key mitigation technologies.
