Analysis on the Hydrodynamic Environment of Philippine Sea and Its Enlightenment to Marine Ecological Zoning

Abstract

Marine hydrodynamic environment, the critical component of marine ecological habitat, provides fundamental conditions for the evolution of marine ecological differentiation pattern and basic guarantee for the realization of ecological functions and services. The Philippine Sea is one of the important centers and origins of global marine biodiversity. Based on the analysis of three-dimensional tempo-spatial characteristics of marine hydrodynamic environment in the Philippine Sea, and combined with the current situation of marine ecological zoning, this paper put forward some enlightening research suggestions. The results showed that the core marine hydrological elements of the Philippine Sea presented the distinct modes of horizontal "five zones differentiation" and vertical "three lines and one circle", which could be used as a basic reference for marine ecological comprehensive zoning. Marine ecological zoning was the strategic basis for sustainable marine development. In the future, China should strengthen marine observation networking and basic data fusion, scientifically divide the boundaries of marine biodiversity protection and resource space management, build a theoretical system of comprehensive zoning scheme and a technical system of comprehensive zoning of classified zoning, innovate a composite classification zoning algorithm, and improve the service capacity of marine ecosystem.
