| 摘 要： | 在垂直压缩三维水动力模型的基础上,建立了包括无机碳、有机碳、二氧化碳、浮游植物态碳、浮游动物态碳、鱼类态碳、沉水植物态碳、底泥中的有机碳、底泥中的无机碳、底泥间隙水中的有机碳和无机碳等状态变量的太湖碳循环三维模型。并用2000年的实测资料进行了参数率定,用2003年的实测数据进行了校验。校验结果显示,绝大多数校验点次的实测值与模拟值间的误差均小于30%,4个校验点的模拟值和实测值的年平均误差均小于40%,由此可见,模型虽然仍需进一步完善,但其已经具有了一定的模拟精度,为太湖湖泊水体碳循环的研究奠定了基础。同时模型计算结果表明:湖泊水体碳循环对大气二氧化碳浓度的降低有正面作用。

| Abstract: | In this paper,a three-dimension carbon cycle model,including several variables such as organic/inorganic carbon in the water,CO2 in the water,carbon in phytoplanktons,fish,and phytobenthons,and organic/inorganic carbon in sediments and the water of clearances,is constructed based on the three-dimension dynamic model.In Taihu lake,the carbon cycle simulation results show that the average difference between the simulation values and the observation values is less than 40% in 2003,so it can be conclusded that the model can simulate the carbon cycle in Taihu lake and can be used to study the carbon cycle in the lake.At the same time,the results of the model show the carbon cycle in the lake can reduce the concentration of CO2 in the air. |
