The existence of the continental shelf front in the Yellow Sea is a critical mesoscale-physical process which can influence the ecosystem of the eastern marginal sea of China，and it is also very important to the local bio-geochemical processes．Based on the introduction and summary of the research progress of the continental shelf front in the Yellow Sea，this paper expounds the ecological functions and ecological effects of the continental shelf front，besides，the development direction and focus of research on the continental shelf front are analyzed，and point out that carrying out the research on the front region ecosystem and the front region ecosystem dynamics can not only become the new growth of the marine ecology，but also provide a new research project for the marine ecology of the Yellow Sea．
