Complexity in Freshwater Ecosystems

doi:10.7523/j.issn.2095-6134.2003.2.001

Abstract

Abstract:

Freshwater ecosystem is of much complexity because of such reasons as: watertype complexity, waterbody formation complexity, biodiversity, ecosystem structure and its function, ecosystem patterns and progress complexity, the complexity of watershed influence and the complexity of human being interference etc. Some advances and trends on freshwater ecology in China are introduced here and other related studies on the main problem--eutrophication of lakes and algal blooms faced in freshwater ecosystem as well. In association with the update trends in international ecology, the prospect of freshwater ecology is discussed. On complexity of freshwater ecology, much progress may be made in the following: RCC (River continuum concept) theory, study on ecology health by way of IBI (Index for Biotic Integrity) and IWI (Index of Watershed Indicators), scaling and fractal, ecosystem management and information system, spatial data analysis and heterogeneity, mathematical model and chaos etc.

Key words: ecological complexity, freshwater ecosystem, eutrophication, water blooms, mathematical model
