| 回顾了河流生态系统结构功能模型的研究进展，介绍了多种重要的概念和模型。在此基础上，提出了河流生态系统结构功能整体模型，它是由河流流态－生态结构功能４维连续体模型、水文情势－河流生态过程耦合模型、地貌景观空间异质性－生物群落多样性耦合模型３个子模型组成。整体模型建立了河流流态、水文情势和地貌景观这３大类生境因子与河流生态系统结构功能和生态过程的相关关系，基本上抽象概括了河流生态系统的主要特征。在模型中除了考虑自然力因素以外，还考虑了水利水电工程设施的干扰作用。

| 英文摘要: |
| The development of fiver ecosystem ecology and some of most important structural and functional concepts of river ecosystem were reviewed. The holistic fiver ecosystem structure and function model is proposed. The bollstic model consisted of 3 sub - model such as 4 - dimension continuum model for structure and function of ecosystem concerning hydraulic condition, the hydrological regime and ecological process coupling model, the diversity of biocenose and heterogeneity of geomorphology landscape coupling model. The relationship between ecological process and main habitat factors including hydraulic condition, hydrological regime and geomorphology landscape is established. The holistic model generalizes the major traits of the fiver ecosystem. In addition to natural factors, the holistic model also takes the impact of hydraulic engineering into account. |
