Environmental Change and Its Influence on Ecosystem Service Values in the Bohai Sea in China

Aimed to reveal the environment change and its influence on ecosystem service value in the Bohai sea in China in last 25 years. The environment change data such as sea primary productivity, marine fishing and main pollutants were collected and surveyed by remote sensing images, and the methods for ecosystem service value assessment were employed to analyze the influence of environment change to ecosystem service value in the Bohai sea. The result show: the primary production, pollutants loading, coastline and sea area have changed greatly in the Bohai Sea since 1988. The environmental changes increased the value of marine ecosystem services value from 529.42 billion RMB in 1988 to 558.83 billion RMB in 2013. The ecosystem services values of recreation, food and materials production, O-2 supply, climate regulation and primary productivity were raised. However, other marine ecosystem services value, including biological control, pollutant purification, knowledge broaden and biodiversity protection were lowered.
