河流不连续体概念及其在河流生态系统研究中的发展现状

Serial discontinuity concept and its development status in river ecosystem research

系统地回顾了序列不连续体概念(SDC)产生与发展的过程以及应用的情况。河流连续体概念对SDC的产生及其最初的形式有着重要的影响。序列不连续体概念的发展经历了最初的形式和扩展形式。利用SDC的扩展形式可以在整个河道内预测由于河流调节所产生的各种不连续生态效应。作为模拟和分析河流再调节计划的理论基础,SDC可以为制订流域新的项目规划以及河流系统整治工作提供指导作用。

The paper systematically reviews the development of the serial discontinuity concept （SDC） and its application. The river continuum concept influences the development of the SDC and its original form. The SDC evolves into two kinds of forms, the original form and the extending one. With its extending form the discontinuity in whole river corridor caused by river regulation can be predicted. As the theoretical base of modeling and analyzing the river re-regulating planning, the SDC can provide guideline for the new project programs of watersheds and the restoration of the regulated rivers. However, there are a few research works about the serial discontinuity concept in China. It is suggested to strengthen the research of this field in order to improve the restoration of river ecosystem.
