Study on Mechanisms of Material Cycling in River Ecosystem with Water, Material and Organism Dynamics

本研究旨在阐明河流过程中水与物质运移与生物群落之间的相互作用系统。这些主题被安排为以下三个子主题：(1)与河岸植被的水-沉积物-有机营养物质运输过程机制；(2)沙坝地表和地下水之间的水-物质相互作用系统；(3)河流藻类、水生昆虫和鱼类的生产和物质循环机制；(4)将这三个子主题的研究结果结合起来进行数值动力学模拟。

The present study is conducted to be clarified the interaction system between water and material transports under fluvial processes with biological communities. These topics are carried out by arranging as the following three sub themes : (1) the mechanism of water-sediment-organic-nutrient material transportation processes with riparian vegetations, (2) the interaction system of water and materials between surface and subsurface water of sand bar, (3) the mechanisms of production and material cycling of riverine algae, aquatic insects, and fish, and (4) the combining of findings from these three sub themes for numerical dynamics modeling.
