摘要:
物质输移扩散规律是大型浅水湖泊水质变化机理研究的重要内容,对湖泊水环境的管理具有重要的现实意义.本文在太湖湖流三维模型研究成果的基础上,创建了太湖保守物质输移扩散三维数值模型,并用之模拟了1997年冬季1~2月太湖总磷含量的变化,计算结果表明,模型计算值与观测值吻合,本文所建的保守物质输移扩散模型,可用于冬季太湖营养盐含量时空变化的计算。

Abstract:
Transportation and diffusion of nutrients and pollutants are one of the important procevS-ses in the large shallow Taihu Lake.They influence not only the distributon of water quality, but also the growth of phytoplankton and the algae bloom.Based on the results of a three-dimensional numerical simulation on the dynamicvS in Taihu Lake, China, a three-dimensional model of transportantion and diffusion of conservative substance has been built.The model has been calibrated by the total phosphorus changes from Jan.18 to Feb.22, 1997.The model results in winter are coincided with the observed.It describes that the model can be used to calculate the pollutants and nutrients transportation and diffusion without consideration of biochemical processes in winter in Lake Taihu, China.
Key words:  Conservation substance  transportation and diffusion  three-dimensional model  Taihu Lake
