In recent decades, nonlinear dynamical systems theory, which includes such approaches and techniques as chaos theory and the theory of dissipative structures, has brought revolutionary advancements to physics, physical chemistry and fluid dynamics. The broad applicability of nonlinear dynamical systems theory makes it appropriate for the study of earth surface processes such as turbulent flow. The increasingly complex nature of problems related to, for example, global environmental change and the interconnectedness of geomorphic and related phenomena demand a more systems oriented approach to their study. Two major schools of thought on geomorphic systems are lodged in North America and Europe, respectively. While North Americans emphasize more contemporary processes, Europeans focus on longer term landscape evolution. Debates of this nature usually take place at major international conferences. The annual Binghamton Geomorphology Symposium is the foremost gathering of scholars in Geomorphology, and in 1992 the Symposium will be organized around the theme of geomorphic systems. This project allows five eminent geomorphologists associated with the European perspective on geomorphic systems to participate in the Binghamton Symposium. Their presence and their contributed papers will provide the basis for a coordinated examination of the role of dynamical systems theory in the study of surficial processes with the ultimate objective of achieving a better understanding of physical landscape change on the surface of the earth. The Binghamton Geomorphology Symposium has, for over two decades, led the way in advancing the research frontier of geomorphological studies. The geomorphic systems theme provides an opportunity to explore the utility of nonlinear dynamical systems theory for the study of earth surface processes and landforms. It should also examine the potential of geomorphic systems studies for predicting the response of earth surface systems to large-scale perturbations such as climate and sea- level change. The participation of the five European experts will fertilize research in geomorphic systems by bringing together geomorphologists from different traditions to discuss and inform each other about the dynamic processes which produce the variety of landscapes present on the earth. The symposium will investigate the utility of chaos and bifurcation theory, dissipative structures, and hierarchy theory for research on the behavior and evolution of specific geomorphic systems. It will further explore the roles of spatial and temporal scale and scale-linkage problems in geomorphology. This project provides a unique opportunity to bring together scholars under the auspices of an established, distinguished symposium format to discuss and debate the future direction of an important subdiscipline within geography.

近几十年来，非线性动力系统理论，包括混沌理论和耗散结构理论等方法和技术，给物理学、物理化学和流体动力学带来了革命性的进步。非线性动力系统理论的广泛适用性使其适用于地球表面过程的研究，如湍流。例如，与全球环境变化和地貌及相关现象的相互关联性有关的问题的性质日益复杂，这就要求对这些问题的研究采取更加注重系统的办法。关于地貌系统的两大思想流派分别存在于北美和欧洲。虽然北美人强调更现代的过程，欧洲人专注于长期的景观演变。这种性质的辩论通常在重大国际会议上进行。一年一度的宾厄姆顿地貌研讨会是地貌学学者的最重要聚会，1992年的研讨会将围绕地貌系统的主题组织。该项目允许五位与欧洲地貌系统观点有关的著名地貌学家参加宾厄姆顿专题讨论会。他们的存在和他们贡献的论文将提供一个基础，协调检查的作用动力系统理论的研究surprisoning过程的最终目标是实现更好地了解地球表面的物理景观变化。宾厄姆顿地貌研讨会，二十多年来，在推进地貌研究的研究前沿的方式。地貌系统的主题提供了一个机会，探讨地球表面过程和地貌的研究的非线性动力系统理论的效用。它还应审查地貌系统研究在预测地球表面系统对气候和海平面变化等大规模扰动的反应方面的潜力。五位欧洲专家的参与将丰富地貌系统的研究，将来自不同传统的地貌学家聚集在一起，讨论并相互通报产生地球上各种景观的动态过程。研讨会将探讨混沌和分叉理论，耗散结构和层次理论在特定地貌系统的行为和演化研究中的应用。它将进一步探讨地貌学中空间和时间尺度以及尺度联系问题的作用。这个项目提供了一个独特的机会，汇集学者在一个既定的，杰出的研讨会形式的主持下，讨论和辩论地理学内的一个重要的子学科的未来方向。
