湖泊富营养化模型的研究进展

Advances in studies on lake eutrophication modelsLiang

湖泊的富营养化是全球普遍关注的环境问题之一。湖泊的富营养化模型是防治、修复和治理湖泊富营养化的重要决策工具。按研究的侧重点不同,将湖泊富营养化模型分为简单回归模型、水质模型、生态模型和生态-水动力水质模型,并分别回顾了四类模型的研究进展。最后指出湖泊富营养化模型的发展趋势,强调不确定理论、3S技术、耦合模型是今后湖泊富营养化模型研究的重点,应在此基础上建立通用的模拟、预测、评价和优化模型,为湖泊富营养化管理提供科学依据。

Recently people around the world have paid more attentions to eutrophication of lakes. Eutrophication models are useful tools to prevent, manipulate and control lake eutrophication. According to the emphases of research, eutrophication models are divided into simple regression models, water quality models, ecological models and ecological-hydrodynamic water quality models in this paper. The development of these eutrophication models is reviewed. The development trend of eutrophication models is pointed out. It is emphasized that models, which based on uncertainties,3S techniques as well as coupled models,are a promised research field. In order to effectively manage eutrophication of lakes, it is useful to develop simulating models, forecasting models, evaluating models as well as optimal models.
