Abstract: The Marine Functional Zoning (MFZ) in Zhejiang province has been carried out for more than five years since 2012.It has played an important role in ensuring the demands of local economic and social development, protecting the marine ecological environment and promoting the rational development and sustainable utilization of the sea area.Meanwhile, the problems have been revealed gradually, for example, some targets are lagging behind, and part of the marine functional zones doesn't fit in with current natural environment and social needs.In order to grasp the condition and effects of the implementation, to find out and solve the problems that exist in the implementation process, it is necessary to periodically evaluate the implementation of MFZ.This paper discussed the theoretical basis and methods of the evaluation of MFZ, proposed the notion of MFZ assessment from single result to multiple process management and control and perfected the evaluation index system.The research results have reference significance for the assessment of MFZ.
