莱州湾陆海污染源多级监测和评价分析系统

渤海是我国唯一半封闭型内海，是我国近岸海域环境问题最为突出的海区之一。近年来由于国家对渤海环境保护和治理工作不断重视，其水质恶化势头得到遏制，但由于缺乏陆海统筹、部门区域联动的控制机制，制约了减排措施的有效实施。而构建支撑陆海协同监控和评价的信息化和智能化系统是解决该问题的关键措施。本文以莱州湾为典型应用场景，通过构建陆海污染源多级监测和评价分析系统，实现高精度多级陆海联动的入海通量监测评估、污染源解析、海域水质变化和入海排污响应分析等主要功能，进而为阐明渤海水质变化和陆源排污关系，建立污染物入海总量控制技术体系和高效精准的减排方案提供参考决策平台。

Laizhou Bay’s multi-level monitoring and evaluation analysis system for land and sea pollution sources

The Bohai Sea, the only semi-enclosed inland sea in China, is one of the most serious coastal areas with environmental problems among the offshore area. In recent years, with the increasing attention of the government to environmental protection and governance in the Bohai Sea, the deterioration of water quality has been curbed. However, due to the lack of a control mechanism for land-sea integration and departmental and regional linkage, the effective implementation of emission reduction measures is restricted. The key measure to solve this problem is to build informatization and an intelligent system that supports land-sea coordinated monitoring and evaluation. Thus, by taking Laizhou Bay as a typical application scenario, this paper implements the following major functions through the construction of land and sea pollution source multi-level monitoring and evaluation analysis system: high-precision multi-level land-sea linkage monitoring and evaluation, pollution source analysis, change of seawater quality, and sea pollution response analysis. These functions further provide a reference decision-making platform for clarifying the relationship between the water quality changes and terrestrial pollution sources, establishing a technical system for controlling the total amount of pollutants into the sea, and providing an efficient and accurate emission reduction plan.
