| 中文摘要 |
| 提出可考虑二维扩散的分区达标控制法用于求解海域环境容量。引进贡献度系数将二维容量问题定义为线性规划问题,使各类水功能区在达到所对应的环境标准的前提下各排污口污染物允许排放量之和最大,并给出了用二维扩散模型计算贡献度系数的方法。将分区达标控制法应用于汕头市海域环境容量研究,表明该方法求出的结果是准确和合理的。 |
| 英文摘要 |
| A programming model is proposed for the optimal allocation of pollutant loads for coastal and estuary water quality management,taking account of the effects of tidal current and two dimensional diffusion.The model is stated as the maximization of total discharged pollutant loads,subject to the satisfaction of environmental standards imposed on the seawater quality of check points which are set along the boundary of water bodies of different utility functions.The model is linear and is solved by Simplex method.Coefficients reflecting the contribution of pollution of each effluent to water quality check points are calculated by numerical simulation with 2D hydrodynamic and diffusion models.The programming model is applied to the water environmental management planning for Shantou City,Guangdong,China,to determine the allowable discharge loads of pollutants to the Yongjiang River estuary. |
