Abstract: This paper uses energy values to establish an estimation method of oceanic ecosystem service based on non-monetary ecosystem service values evaluation, which is used to estimate China's oceanic ecosystem service values in 2012 with objectives of providing reference for governmental managements in planning oceanic resources. According to oceanic ecosystem service values in 2012, China's 13 coastal provinces (cities) are ranked as follows: Guangdong, Shandong, Taiwan, Fujian, Hainan (Sansha city excluded), Liaoning, Zhejiang, Jiangsu, Shanghai, Guangxi, Hebei, Tianjin and Sansha city (only coral reef and sea grass bed considered). Seven categories of oceanic ecosystems whose unit service values are in a decreasing order are mangrove, salt swamp, tidal flat, estuary, sea grass bed, warm water coral reef and 12 sea miles water, suggesting a bigger unit ecosystem service value in shore wetland, compared to coastal water. So protection of existing shore wetland ecosystem or expansion of its area helps increase oceanic ecosystem service values. The major ecosystem services include increasing biological diversity, fixing carbon and releasing oxygen, and natural power generation with their contribution over 70%.
