Abstract：Based on the analysis of humanocean relationship，this article argues that mankinds maritime culture has experienced three updated versions in history， while Chinas current construction of marine ecological civilization， as the newest achievement embodying a tendency of ecological turn of maritime culture worldwide， intrinsically points to and calls for a systemic ecological turn of Chinese maritime culture， thereby implies a historic moment for version upgrading. The ecological turn therefore should be consciously promoted towards an upgraded version of maritime culture that orients on harmonious humanocean relationship， being mutually compatible and supportive with the marine ecological civilization. At present its essential to solve the problem of insufficient ecological attention and social mobilization power with Chinese maritime cultural discourse. The discourse could be upgraded through four creative paths and the upgraded discourse should find its effective expressions in various discourse fields. This will consequently not only boost the construction of marine ecological civilization and the contemporary development of maritime culture， but also contribute to China's image as a sea power and the international spread of Chinese maritime culture．
