| 摘 要： | 本文讨论了河流中BOD—DO动态的数学模拟方法,并将该方法应用于图们江,利用在图们江上取得的实测数据建立了江中BOD—DO动态的数学模型。在所得到的模型中,耗氧系数κ_1,复氧系数κ_2,BOD沉淀-再悬浮系数κ_3被表达为流量与水温的函数。表达式中的参数通过系统识别与参数估计方法确定,因此能较好地反映河流的地理环境特点。特别是κ_3的表达式,它以流量为自变量,用一个单一的解析函数同时描述了江中的沉淀与再悬浮现象,具有独创性。 本文所提出的BOD—DO动态模型可以做为图们江水质规划与管理的基础。

| Abstract: | A method for mathematical modeling of the BOD-DO dynamics of a river is described. The method is applied to field data collected on Tu Men River in North-Eastern China. In this model of Tu Men River quality the functional structures of the deoxygenation coefficient k1, reaeration coefficient k2 and BOD sedimentation-resuspension coefficient k3 are established and tbe parameters determined by a regression technique to suit the characteristics of a river in the mountain area of North-Eastern China. In the model the sedimentation-resuspension coefficient k3 is given in the form of a single analytical function of the flow rate in the river. The model can also be used as basis for a river quality management scheme to be carried through on Tu Men River. |
