The recognition that climatically modulated erosion acts to govern the development of active mountain ranges is arguably one of the most transformative conceptual shifts in the geosciences subsequent to the plate tectonic revolution. Topography in tectonically active regions results from an interplay among climatic, tectonic, and surface processes. The building of mountains increases topographic slopes, which directly influences the rate and efficiency of erosional processes. Rising landmasses can also influence climate by altering patterns of airflow and heating, influencing the magnitude and pattern of precipitation. Feedbacks between the redistribution of mass by climate-driven erosion can influence the state of stress, thermal structure, and subsequent deformation patterns within mountain belts, the very mechanisms that drive the growth of topography. The strength of these various interactions and coupling, however, is still contested. Furthermore, these processes have strong impacts on the well being of humans living in mountainous terrains. This project supports a U.S.-Taiwan workshop that would assess the current state of research and identify future interdisciplinary research directions. A key objective of the workshop is to increase partnerships between the U.S. and Taiwan through the development of collaborative research projects that benefit from research expertise in both countries, thereby strengthening research activities within each country while advancing understanding of the complex linkages among mountain building, climate, and surface processes. The participation of students and early-career scientists in the workshop will ensure the development of long-term collaborations that are mutually beneficial both from the perspective of the development of the scientific workforce and the exchange of scientific ideas. This project supports the participation of U.S. based scientists in a U.S. Taiwan workshop, which will be held at Oregon State University in 2017. The overarching purpose of this workshop is to promote interdisciplinary research on the linkages and feedbacks among mountain building, climate, and surface processes. The active Coast and Cascade Ranges, which will be explored during pre- and post-meeting field trips, will provide the backdrop for the workshop. Specifically, the workshop goals are four-fold: (1) evaluate the current state of understanding in how feedbacks among climate, mountain building, and landscape evolution govern the trajectory of orogenic systems; (2) identify and refine research goals that capitalize on transdisciplinary approaches that will lead to the next set of advances in our understanding of coupled solid and fluid earth systems; (3) strengthen emerging collaborations between U.S. and Taiwan scientists and to foster the development of specific research strategies to address research goals; and (4) broaden the scope of research goals to include systems beyond the Taiwan orogeny and to increase participation from a broader swath of U.S. researchers. The workshop is organized around two key themes: This project is supported by the Tectonics Program and the Geomorphology and Land Use Dynamics (both in the Earth Sciences Division, Geosciences Directorate) and NSF's Office of International Science and Engineering.

在板块构造革命之后的地球科学中，可以说，对管理主动山脉发展的气候调节行为的认识可以说是最具变色的概念转变之一。构造活动区域中的地形是由于气候，构造和表面过程之间的相互作用而产生的。山的建造增加了地形斜坡，这直接影响了侵蚀过程的速度和效率。上升的陆地还可以通过改变气流和加热的模式来影响气候，从而影响降水的幅度和模式。通过气候驱动的侵蚀对质量重新分布之间的反馈会影响压力，热结构和随后的山带变形模式，这是驱动地形生长的机制。然而，这些各种互动和耦合的优势仍然有争议。此外，这些过程对生活在山区的人类的福祉产生了强烈的影响。该项目支持一个美国台湾研讨会，该研讨会将评估当前的研究状态并确定未来的跨学科研究指示。研讨会的一个关键目标是通过开发合作研究项目来提高美国和台湾之间的伙伴关系，这些研究项目受益于两个国家的研究专业知识，从而加强了每个国家 /地区的研究活动，同时促进对山区建筑之间复杂联系的了解，和表面过程。从科学劳动力的发展和科学思想的交流的角度来看，学生和早期科学家在研讨会中的参与将确保长期合作的发展。该项目支持美国科学家在2017年在俄勒冈州立大学举行的美国台湾研讨会的参与。该研讨会的总体目的是促进有关山区建筑，气候和地表之间的联系和反馈的跨学科研究过程。将在会议前和后的实地考察期间探索的活跃海岸和级联范围将为车间提供背景。具体而言，研讨会目标是四倍：（1）评估气候，山区建筑和景观演化如何控制造山学系统轨迹的当前理解状态； （2）确定并完善研究目标，以利用跨学科方法，这将导致我们对耦合固体和流体地球系统的理解的下一步进步； （3）加强美国和台湾科学家之间的新兴合作，并促进针对研究目标的特定研究策略的制定； （4）扩大研究目标的范围，以包括台湾造山基础以外的系统，并增加了更广泛的美国研究人员的参与。研讨会围绕两个关键主题组织：该项目得到了构造计划和地貌和土地利用动态（都在地球科学部，地球科学局）和NSF国际科学与工程办公室的支持。
