意味

Tidal flat; mudflat. A coastal area of soft sediment that is exposed at low tide and submerged at high tide, serving as a vital habitat for marine organisms and migratory birds.

A noun combining 干 (to drain or dry out) and 潟 (lagoon or tidal inlet). 干潟 ecosystems are among the most biologically productive in the world, supporting shellfish, wading birds, and juvenile fish. In Japan, many tidal flats were lost to land reclamation during the post-war economic boom, and their ecological restoration has become a significant environmental policy concern.
