Abstract: Sandy coast is one type of coastal wetland ecosystems, which has important ecological service functions and is also susceptible to human activities and global changes. In September and December 2022, 10 survey profiles were set up on the sandy coast in the Shenhu Bay, Fujian Province to conduct observations of the terrain and geomorphic characteristics as well as measurements of sediment granularity. A comprehensive evaluation of the natural resource endowment and disaster bearing capacity of the sandy coast in the Shenhu Bay was conducted based on the related national standards which provide corresponding indexes and grading criteria. The overall natural resource endowment of the sandy coast in the Shenhu Bay is good, but due to factors such as seaward width and relative tidal range, the natural disaster bearing capacity is moderate. The research results provide first-hand basic data of Shenhu Bay, and provide technological support for improving the natural resource endowment, natural disaster bearing capacity, and protection and restoration of the sandy coast in the Shenhu Bay.

Key words: Shenhu Bay, Sandy coast, Sediment granularity, Resource endowments, Disaster bearing capacity, Fujian
