摘要
讨论了人工湿地三种常用的数学模型(衰减方程、一级动力学模型和生态动力学模型),并对其研究历史、发展应用、理论基础、基本形式、建立方法,及其各自的优缺点做了分析。从中可以看出,人们对人工湿地去除污染物的内在机制尚缺乏定量化的了解,目前还很难对其的设计、运行和预测做出准确的评价,因此影响了这一高效低耗的生态污水处理技术的推广和应用,而人工湿地生态动力学模型的不断完善可以从根本上解决这一问题。
Regression equation,First dynamic models and Ecosystem kinetic models of artificial wetlands are discussed in this paper,their histories,applications,characteristic,theories,structures and building method are presented.Artificial wetlands are dynamic ecosystems for which is not yet completely understood and which we generally have poor predictive capabilities.Ecosystem kinetic models provide us with a useful tool for understanding wetland function and structure,testing hypothsis and making prediction.
