高海拔或高纬度山区（尤其高山冰川及冻土急剧消退区）常孕育适宜泥石流发育的地形和物源条件。气候变化（如升温、强降雨事件增多等）影响下,高山区潜在孕灾环境更易于成灾,泥石流成为主要的灾害类型和物质输移方式,也是高山区地貌变化的重要驱动力。由于野外监测困难,数据资料匮乏,鲜有针对高山区泥石流过程地貌效应的分析报道。以中国藏东南高山区泥石流多发的帕隆藏布流域为研究区,以古乡沟、天摩沟和扎木弄沟为典型小流域,结合遥感影像、DEM数据、无人机航拍、高精度RTK测量和野外踏勘调查,分析泥石流沟道地貌发育特征（冲淤变化、平面摆动）及其对主河河流地貌的影响,并探讨大规模泥石流事件影响下河谷地貌的长期演变趋势。高山区泥石流过程强烈塑造沟道自身地貌,上游物源区深切展宽和溯源蚀退,沟口堆积扇冲淤变化受控于泥石流事件规模和水流强度。泥石流过程显著影响主河道河流地貌,造成主河道横向冲淤和摆动,并影响堰塞体上游河段平面形态发育。长时间尺度上,河谷地貌在平面上发育形成宽窄相间的藕节状而在纵剖面上形成台阶状形态。 相似文献

2011年2月13日18时35分,我国杰出的地理学家、中国科学院院士、中国现代冰川、冻土、泥石流科学的开拓者和奠基人施雅风先生离开了我们。施雅风院士是我国泥石流研究的奠基人,对我国泥石流科学研究事业的开创、发展倾注了大量心血,培养了大批研究人才,为我国成为世界泥石流研究强国作出了卓越的贡献。从1963年9—10月他率队开始考察西藏波密古乡冰川泥石流,至2011年1月发表庐山泥石流和第四纪冰川的讨论文章,施先生研究泥石流近半个世纪。施先生去世后,作为泥石流研究者,作为施雅风先生当年的同事和晚辈,我们搜集和查阅了大量有关泥石流研 相似文献

对西藏古乡沟泥石流模型试验中的模型砂配制进行了研究,旨在保证模型试验的合理性和科学性,从而为泥石流灾害防治工程提供可靠的设计依据。通过对泥石流形成区和堆积区样品的粒径分析,根据模型试验的目的和条件,选定模型的几何比尺为1∶100,但模型砂的配制采用泥砂分段模拟法,原型中小于0.1 mm的颗粒不缩小,仍按重量百分比配制;原型中大于0.1 mm的颗粒按相似比尺缩小后用小于0.1 mm模型砂代替。并通过模型样品的选用和粒径组合对泥石流体以及堆积扇的模型砂配制过程进行了详细的分析研究,使模型试验获得了比较好的结果。 相似文献

培龙沟泥石流及其堵江可能性探讨 总被引：2，自引：0，他引：2
培龙沟是由冰川和降水共同激发的一条大规模泥石流沟。流域内充足的冰水资源，丰富的冰碛，有利的地形条件是泥石流发生及今后发展的动因。1983-1986年培龙沟泥石流堵塞了帕隆藏布江，本文就今后不同泥石流发生频率探讨了泥石流再次堵江的可能性。这一探讨为该沟泥石流工程整治及过沟工程设计提供科学依据。 相似文献

新平县曼蚌河滑坡型泥石流特征及治理 总被引：4，自引：0，他引：4
曼蚌河是地处新平县腰街镇的一条老泥石流沟，属红河二级支流，在2001年以前的近50年间未暴发过泥石流。2000年在中游芭蕉箐支沟源头一带发育一大滑坡，活动后形成滑坡型泥石流，阻塞主沟溃决形成主沟泥石流危害下游。其形成及活动过程非常复杂，支沟为滑坡型粘性泥石流，龙头高近20m，有气垫效应产生。通过勘察、量测，查明了该沟滑坡型泥石流的发育、活动特征及形成机理等。通过3方案比选优化最终确定了“拦挡、排导为主，辅以稳坡固床”的泥石流防治方案。 相似文献

<正>1 Introduction In 2013,Chagusaba,which is traditional tea-grass integrated system in Shizuoka,were accepted as new world heritage site of agriculture.Shizuoka prefecture occupies a variety of elevations,from 0 to 3000m or more above sea level.Because of the diversity of land features and climates,this area produces 167 agricultural commodities.In addition,a lot of traditional agriculture and over200 local native varieties of crops have been conserved in Shizuoka 相似文献
