关于水域纳污能力计算理论的总结与思考

Summary and Reflection on Calculation Theories of Assimilative Capacity of Water Body

科学认识、合理计算水域纳污能力对促进污染减排、实现水功能区限制纳污红线管理至关重要。在系统调研大量水域纳污能力计算理论相关文件、报告、书籍、规范、文献的基础上,总结归纳现有水域纳污能力内涵、计算方法和原则选用、设计条件和参数确定等,并对其优缺点、适用性等进行讨论,最后提出新形势下细化、强化水域纳污能力计算的合理性分析与检验、推进水文-水动力-水质-纳污能力耦合研究等发展方向。研究成果可为水域纳污能力科学、合理、准确计算提供参考依据。

Scientific understanding and reasonable calculation of water’s assimilative capacity is of crucial significance to the pollution reduction and the red-line management of water functional area.We summarized the existing connotations,calculation methods,principle selections,design conditions and parameter determining of water’s assimilative capacity based on systematic investigation of a large number of documents,reports,books,specifications and articles related to the calculation theory of assimilative capacity.We also discussed the advantages and shortcomings as well as their applicability.In addition,we put forward the development directions:refining and strengthening the rationality analysis and verification of the calculation of assimilative capacity;promoting the coupling research of hydrology,hydrodynamics,water quality and pollutant carrying capacity.The research offer reference for the scientific,reasonable and accurate calculation of assimilative capacity of water body.
