Abstract: Abundant tidal flat resources in Hangzhou Bay give rise to strong demand of utilization. To regularize the exploitation and make it rational and sustainable, resource zoning is carried out. Protection zone, reservation zone, control zone and exploitation zone are divided to ensure the orderly exploitation and to protect natural environment and tidal bore, and to maintain the safe operation of important infrastructures. The detailed approaches, considerations and result of tidal flat zoning in Hangzhou Bay are expounded in this paper. It could be regarded as a reference for tidal flat management and protection in other areas.

Key words: Hangzhou Bay, tidal flat resource, zoning, management of tidal flat resource
