BIOCOMPLEXITY -- INCUBATION ACTIVITY: Dynamic Controls on Emergent Properties of River Flood Plains

斯坦福德河目前被视为与集水区设置和产水量有关的线性河段，其中的物质呈螺旋形向下游旋转。该项目旨在将科学转向一种非线性的、更动态的观点，强调能量分散和材料保留是河流生态系统的主要组织元素。这项研究在概念上基于这样的观点，即冲积洪泛区是区域生态组织的中心，因为动态的、非线性的过程将水和物质的流动和保持与相互作用的景观形成过程联系起来。这种相互作用创造了一个复杂的、动态的资源补丁和界面阵列，从而产生了生物多样性的区域热点(包括非常广泛的迁徙物种)。系统动态的重要修正因素包括干旱、野火、水流和地貌调节(水坝和护岸)以及外来物种的入侵。跨学科小组将根据现有的经验数据开发一个专家系统，描述冲积洪泛区的结构和功能。该团队将使用现有的、新颖的模拟器，在蒙大拿州西部的一片大洪水平原上，在特定的水流中引导水。一项主要任务是制定一个战术计划，以完善模型，使其能够由遥感数据驱动。

0083884StanfordRivers are currently viewed as linear segments where materials spiral downstream in relation to catchment setting and water yield. This project is designed to shift science toward a non-linear, more dynamic view that emphasizes energy dispersion and materials retention as the primary organizing elements of river ecosystems. This research is conceptually based on the view that alluvial flood plains are regional centers of ecological organization, owing to dynamic, non-linear processes linking water and materials flux and retention to interactive landscape-forming processes. This interaction creates a complex, dynamic array of resource patches and interfaces, thereby producing a regional hot spot of biodiversity (including a very wide array of migratory species). Important modifiers of system dynamics include drought, wildfire, flow and geomorphic regulation (dams and revetments) and invasions of nonnative species. The interdisciplinary team will develop an expert system derived from available empirical data describing the structure and function of alluvial flood plains. The team will use an existing, novel simulator that routes water during specified flows through a large flood plain in western Montana. A primary task is to develop a tactical plan for refining the model to allow it to be driven by remotely sensed data.
