| 摘 要： | 湖泊营养物基准参照状态的科学合理确定是营养物基准制定的重要技术基础之一。以四川邛海为例，将系统动力学模型耦合多种数学模型，对湖泊营养物的产生、分布及输移进行系统模拟，并结合系统反演方法获得湖泊近几十年不同水文条件下的各营养物浓度演化过程及湖泊富营养化水平。结果表明，经过试验校准的系统仿真模型能够较真实地反映湖泊历史富营养化变化过程，据此确定了湖泊营养物基准参照状态：TP浓度为0.008~0.015 mg/L；TN浓度为0.286~0.323 mg/L；Chl-a浓度为2.140~4.211 μg/L；透明度(SD)为1.862~2.731 m。 |

| Abstract: | Establishing lake nutrient reference conditions scientifically and reasonably is one of essential technical foundations for nutrient criteria determination. A system dynamics-based method, combined with several mathematical models, was undertaken to simulate the nutrient sources, distribution and movement in Lake Qionghai, Sichuan Province. The evolution process of nutrient concentrations and eutrophication levels in the past decades under different hydrological conditions was modeled by a system retrieval method. The results showed that the system simulation model calibrated by experiments was capable of describing the historical changes of lake eutrophication. Accordingly, this new method identified the reference total phosphorus values of 0.008-0.015 mg/L, reference total nitrogen values of 0.286-0.323 mg/L, reference chlorophyll-a values of 2.140-4.211 μg/L, and reference Secci depth values of 1.862-2.731 m for Lake Qionghai. |
