Shuitu Baochi Xuebao, 2005 风沙流的危害是多方面的,不仅破坏地表结构,削弱土壤的抗风蚀性,而且影响到植物的生长,损坏工农业设施。通过在便携式风洞内模拟挟沙气流,研究了风沙流对土壤风蚀的影响。结果表明,风沙流可不同程度地降低土壤地表结构的临界起沙风速,使土壤变得更易风蚀。风沙流因子对于土壤风蚀的影响,在不同的风速段具有不同的特征。在较低风速段,风蚀量随风速增加缓慢,当风速进一步加大,风蚀量则急剧增加,其差异最多可达4倍之多;而当风速增大到10m/s以上时,风蚀量反而有所减小,说明随着风速的加大,更多的沙粒具有了更大的动能 ...

Computational Simulation of Landform Change in a Fluvial-Aeolian Interacting Field [PDF]
, 2018 传统上对干旱地区地表环境的研究是以风蚀动力为主，然而地球地貌的演化是各种自然过程及环境因子相互作用的结果，风蚀地貌亦然。自20世纪60年代以来，不断有研究人员注意到地球甚至火星地表风蚀沙丘与河流相互影响的现象或痕迹，发现地球地层记录中广泛存在干旱环境的风水交互沉积，从而认识到风水交互作用对地貌的发展与环境变化的联系。但由于风蚀、水蚀地貌的驱动机制不同，风沙地貌与流水地貌的研究是相对独立发展的。因此，研究不同时空尺度下风水交互作用的动力机制、风水交互作用对土壤侵蚀 ...

Bipartisan Failures: How Political Agendas Undermine Core Ethical Principles in Emergency Management
Politics &Policy, Volume 53, Issue 6, December 2025.ABSTRACT This paper examines how political agendas across the ideological spectrum compromise ethical principles in emergency management in the United States. Through a literature review and comparative fact‐based scenario analysis, it demonstrates that both conservative and liberal governments have politicized disaster declarations, resource ...
