流域生态学及模型系统

Watershed ecology and modeling system

流域生态学是一门复杂的交叉学科,主要研究流域自然、社会和经济之间的动态关系。虽然流域生态学的发展较晚,尚处于初期阶段,但却有重要的研究意义和应用前景。分析了目前国内外流域生态学研究的现状和存在的问题,然后结合在荷兰参与流域生态研究的经验探讨流域生态学研究的一些思路和框架;重点论述了如何应用现代计算科学和信息技术建立流域生态学研究的定量方法和模型系统,最后给出了荷兰Veluwe湖和莱茵河下游的流域生态研究及模型实例。

watershed ecology is a complex and interdisciplinary subject which investigates the dynamics between nature, society and economy. However, at the present watershed ecology mainly focuses on the mutual interactions between water resources and ecosystem with the disturbance from human activities. Although watershed ecology is a relatively new topic and it is at the infant stage, it has great research significance and promising practical applications. This paper first reviewed the recent developmens of watershed ecology, and then emphasized the framework of future research in this field by incorporating the experiences in watershed research in the Netherlands. The paper especially highlighted the applications of the advanced computation science and information technology to developing quantitative methods and modeling system for watershed ecology research. The case studies of the watersheds of the Veluwe Lake and the River Rhine in the Netherlands were presented as well.
