基于ELCOM-CAEDYM模型的淀山湖营养物投入响应关系的模拟
Simulation of the response of algal growth to nutrients input in Lake Dianshan based on ELCOM-CAEDYM model
摘要
Abstract
The lake Dianshan is suffered from eutrophication problem. Based on the ELCOM-CAEDYM model, this paper simulated the water quality of Lake Dianshan in 2008, settled a set of parameters applicable for the simulation, and validated the simulation result. The water-temperature simulation result was satisfactory, which indicated that the all-year simulated fluctuation of TN,TP and algal concentration agreed with the measured data. Furthermore, this paper applied the model in simulating the effect of nutrients input ( nitrogen and phosphorus) on algal growth in Lake Dianshan. The simulation result revealed that the concentration of Chl. a changed significantly with input amount of phosphorus in Lake Dianshan. The increasing of input amount of nitrogen has not affected the concentration of Chl. a. But if the concentration of TN were lower than the critical value of 3.70- 4.31mg/L, the concentration of Chl. a would decrease obviously in Lake Dianshan.关键词
