| 1 | Modeling Experiment of Break of Debris-Flow Dam显示文摘Glaciers are extensively developed in the southwest of Tibet and the moraines are widely distributed with large depth. Large-scale debris flows are often reported which blocked rivers and formed dams. In this paper,seven large debris flows in four valleys are discussed,among which five dams developed. 13 sets of ex-periments have been conducted in laboratory to simulate the forma-tion and failure of the dam. Finally,a model of dam failure is pro-posed and a formula is established to calculate the flood discharge:Q k bh hk BG0.41= T L,where bk is the outlet width of the dam at the original water level,hk the erosive depth,T the time from overflow to final state of failure,the average width of lake;L the length of the lake,and G the total potential energy of the water in the lake. | CHENG Zunlan GENG Xueyong DANG Chao LIU Jingjing | 2007 | Wuhan University Journal of Natural Sciences2007，12，4： | 3 |
| 2 | Assessing the effectiveness of protecting reserves for nature assets in China显示文摘评估保护自然财产的有效性是保护的区域的应答的、积极管理的一个重要部件。保护储备是重要的地质(包括的石块) 是的财产也保护国家、自然的遗产的一个工具。在 2013 的结束, 2669 个保护的区域在中国被建立了,他们中的 123 个是为自然财产的储备。这份报纸为这些财产的保护有效性造一个评估框架。为有效保护的当前的元素和特征被分析,与存在问题的分析一起以便构造一条科学途径保护这些财产。为自然财产储备的有效保护的影响元素和特征在如此的区域为有效保护在一个索引评估系统被包括,它包含四部分目标层,评估标准,评估索引,和在相关文件和文件上基于参数的评估。为目标层,它包括自然财产评估和管理评估。最后,怎么造一个全面评估模型并且完成有效量的评估,被讨论。 | WEI Dongying LUO Zunlan LIJunsheng WANG Wei ZHANG Mengmeng | 2015 | Journal of Geographical Sciences2015，25，4： | 1 |

| 7 | Debris Flow Dam Formation in Southeast Tibet显示文摘Glaciers with their deposits abound in the alpine areas of Southeast Tibet. Large debris flows occur frequently from these deposits and form dams that block streams. In this paper,3 events of large debris flows reported in Peilong Valley located in Southeast Tibet,and which resulted 2 blocking dams resulted,are discussed in details,focusing on the major factors controlling dam formation. The results shows that the first surge group caused by snow and ice avalanches,ice-lake breaks,and large-scale landslides,with a high peak discharge and high velocity,and an abundance of boulders,are most likely to form blocking dams. | CHENG Zunlan WU Jishan GENG Xueyong | 2005 | Journal of Mountain Science2005，2，2： | 0 |
