在这项研究中，一个单一的盒子生态系统模型评估四个藻类群体（绿色藻类，蓝绿色藻类，硅藻/甲藻，和隐藻）在一个平坦的，低洼的农业区的三个富营养化水库。这些水库被用作农业水资源，它们在水深、蓄水量和植被等特性上各不相同。2009年7月至11月每周进行一次水质调查，包括每种藻类的叶绿素浓度、总有机碳（TOC）、溶解有机碳（DOC）、总氮（TN）、总磷（TP）和溶解氧（DO），以验证生态系统模型的有效性。该模型可评价不同富营养化水库水质的季节变化，并可估算与藻类季节变化相关的营养盐动态特征。研究结果表明，该模型可用于模拟浮游植物和营养盐之间的关系，以及在短暂但关键的时期，当强烈的富营养化发生藻类的物种组成的季节变化。版权所有© 2013约翰威利父子有限公司.
In this study, a one‐box ecosystem model evaluating four algal groups (green algae, blue‐green algae, diatoms/dinoflagellates, and cryptophytes) was constructed for three eutrophic reservoirs in a flat, low‐lying agricultural area. These reservoirs are used as agricultural water resources, and they differ in characteristics such as water depth, storage capacity, and vegetation. Water quality surveys of the chlorophyll‐aconcentration of each algal group, total organic carbon (TOC), dissolved organic carbon (DOC), total nitrogen (TN), total phosphorus (TP), and dissolved oxygen (DO) were conducted weekly, from July to November 2009, to verify the validity of the ecosystem model. The model evaluated seasonal changes in water qualities for the different eutrophic reservoirs and could estimate the dynamic characteristics of nutrients related to the seasonal changes in algae. The study showed promising results and the model could be used to simulate the relationship between phytoplankton and nutrients, as well as seasonal changes in the species composition of algae during the brief but critical period when strong eutrophication occurred.
