The reasonable distribution of COVID-19 testing facilities is a crucial public necessity to protect the civil right of health and the proper functioning of society in the post-epidemic period. However, most of the current COVID-19 testing facilities are in large hospitals in China, partially overlooking the COVID-19 testing needs of rural dwellers. This paper used shortest-path analysis and the improved potential model to measure the accessibility of current and potential COVID-19 testing facilities, superimposing this with the testing demands of residents, as calculated by the population demand index, so as to comprehensively evaluate the equity of the spatial allocation of the current and potential testing facilities, with a particular focus on Haishu District, Ningbo City, China. The results revealed that the overall accessibility of the current testing facilities in Haishu District was high, while the internal spatial differentiation was considerable. The comprehensive accessibility of testing facilities gradually declined from the downtown areas towards the rural areas. Moreover, roughly half of the rural population needing COVID-19 tests encountered hindrances due to poor access to testing agencies. However, after fully exploiting the potential testing facilities, the comprehensive accessibility of testing facilities was significantly improved, and the inequity in the accessibility to testing facilities was effectively alleviated, which significantly improved the equity of the allocation of testing facilities in Haishu District. The leveraging of current medical facilities to boost the number of testing facilities in rural areas could eliminate the disparity of resource distribution caused by urban and rural binary opposition, and could quickly identify external sources of COVID-19 in rural areas in the post-epidemic period. Moreover, efficient COVID-19 testing combined with the travel records of infection carriers can effectively identify unknown infection cases and obviate large-scale infection outbreaks.

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.
