| 摘 要： | 本文建立了浅水湖泊水质系统滤波模型和相应算法。根据滇池流场比较稳定等特点。对湖泊进行单元分区，考虑模型误差扰动和观测误差扰动的存在，建立系统的状态方程和观测方程，用吉尔（ＧＩＬＬ）算法求解微分方程，进行系统多点连续模拟和实时预报，用此法对滇池１９８８年的ＢＯＤ、ＣＯＤ时空变化进行连续预报，取得满意效果。

| Abstract: | The water quality system filter model and its algorithm in shallow lake have been established in thes paper. On the basis of relative stability of flow field, considering the disturbances of model error and observation error, the state equation and observation equation of the system can be deduced by dividing the lake into calculated units. The model has properties of continuous simulation and real-time prediction by employing GILL method to solve differential equation. BOD and COD concentrations during 1988 in Dianchi Lake, Yunnan province have been simulated. The computed results by using this model are in good agreement with field observation data. |
