With the rapid development of urbanization and industrialization, human activities have caused marine pollution in three ways: land source, air source, and sea source, leading to the problem of marine environments. Remote sensing, with its wide coverage and fast and accurate monitoring capability, continues to be an important tool for marine environment monitoring and evaluation research. This paper focuses on the three types of marine pollution, namely marine seawater pollution, marine debris and microplastic pollution, and marine air pollution. We review the application of remote sensing technology methods for monitoring marine pollution and identify the limitations of existing methods. Marine seawater pollution can be effectively monitored by remote sensing technology, especially where traditional monitoring methods are inadequate. For marine debris and microplastic pollution, the monitoring methods are still in the early stages of development and require further research. For marine air pollution, more air pollution parameters are required for accurate monitoring. Future research should focus on developing marine remote sensing with data, technology, and standard sharing for three-dimensional monitoring, combining optical and physical sensors with biosensors, and using multi-source and multi-temporal monitoring data. A marine multi-source monitoring database is necessary to provide an immediately available basis for coastal and marine governance, improve marine spatial planning, and help coastal and marine protection.

Marine functional zoning is a basic form of marine management proposed and organized by the Chinese government in the late 1980s, and the third round of planning and implementation has been completed. Effectiveness evaluation of marine functional zoning is an important tool to supervise the implementation of marine functional zoning and improve the level of marine management. For the first time, based on the concept of consistency, based on the planning blueprint, with the sea area use compliance, environmental quality compliance and development and utilization impact as the evaluation benchmark, this paper attempts to integrate and construct the coordination discrimination method of sea area utilization status and marine functional zoning, that is, the coordination index of marine functional zoning, and takes Wenzhou as an example. The research shows that the coordination index of marine functional zoning in Wenzhou is 0.81 during the planning period, and the implementation effect of marine functional zoning is good. Empirical research shows that this evaluation method can provide basic guidance for scientific compilation and effective implementation of marine spatial planning.
