| 中文摘要: |
| 动、植物体以及其他有机生命体在水生态系统中的传播过程逐渐成为近年来最为活跃的研究领域之一。水媒是滨水植被的基本传播途径，可以实现大量繁殖体的长距离输运，同时为后续的繁殖体定植提供适宜的环境及物质条件，是最具效率的传播媒介。本文以植物繁殖体为典型有机生命体，对主要传播媒介与途径进行梳理并分析其特点，进一步总结了其经水媒周期性传播过程及其在群落动态演化中的主导地位，并就主要干扰因素进行归纳并分析其作用机制，对水媒传播过程中繁殖体动力学特性进行描述。重点对长距离水媒输运的关键意义、研究手段与描述方法进行介绍，对研究现状与存在的问题进行分析，从水动力学角度对输运过程中的关键机制进行剖析，并阐明其在构建集成化的动态耦合模型中的作用。 |

| The dispersal of plants, animals and other organisms in aquatic ecosystems has become one of the most active research fields in recent years,as the essential dispersal mode of riparian vegetation,hydrochory can make long-distance migration of millions of propagules, and create suitable conditions for subsequent establishment and growth. In this paper the propagule is selected as typical living organism, the main medium and pathway of its dispersal have been summarized and analyzed. Further,the periodic hydrochory of propagules are summarized and its role in dynamics of plant community, interference factors of which are summarized and analyzed, and dynamics characteristics of the propagule in hydrochory have also been depicted. The means and characteristic methods of long-distance transport, the existing condition and problems of which are analyzed in the study. The essential mechanisms of hydrochory are dissected in the view of hydrodynamics,and their roles in building integrated coupling models are clarified. |
