洞庭湖生态水文研究进展与展望

Research progress and prospect of ecological hydrology in Dongting Lake

生态水文科学研究的核心内容是揭示不同尺度、多层次的环境条件下生态景观变化与水文过程的相互响应机理,尤其是植物与水之间的相互关系。介绍了洞庭湖生态水文的主要研究内容,基于洞庭湖生态水文物理和化学过程研究不够完善,生态水文模型数量少、创新少,生态水文修复起步晚且单一等问题,指明了加强洞庭湖生态水文的机理研究、完善和改进洞庭湖生态水文模型、提高生态水文修复在洞庭湖治理中的作用等生态水文的研究方向,以期为洞庭湖后续的研究提供参考。

The core content of the research is to reveal the interaction mechanism between the ecological landscape changes and the hydrological processes in different scales, especially the relationship between the plant and water. The main research contents of Dongting Lake ecological hydrology were introduced. Because ecohydrological physical and chemical process research in Dongting Lake is not perfect, ecohydrological model number is less, and innovative is less, hydrological and ecological repair is late, and so on. In order to provide important reference value for the study of the Dongting Lake, eco hydrological progress and research direction for research of Dongting Lake were pointed out, ecohydrological mechanism science should be strengthen,Dongting Lake ecohydrological model should be improved, and ecohydrological restoration should be increased in the function of Dongting Lake governance.
