Abstract: Protected areas in the coastal and marine space provide critical habitats for a wide range of marine species, they are interconnected through maritime zones, forming a natural protected area connectivity network. Since the designation, construction, and management of these areas are primarily carried out at the provincial level, conducting research on protected area networks at this scale is essential for advancing the development of the national protected area system. This study focuses on coastal and marine space of Zhejiang Province to analyze the distribution and spatial pattern of its protected areas. The results indicate that protected areas in the coastal and marine space of Zhejiang Province exhibit a rich and diverse typology, with relatively balanced composition and spatial distribution. By analyzing the current distribution patterns and key anthropogenic influencing factors, this study identified three distinct zones: protected area contraction zones, protected area expansion zones, and ecological corridor zones, which provides a scientific basis for the future spatial layout of protected areas in the coastal and marine space of Zhejiang Province.
