Loss appraisal on the value of marine ecosystem services of the sea reclamation project for Caofeidian
曹妃甸围填海工程的海洋生态服务功能损失估算

In this paper, the market value method, alternative cost method and shade project method were employed to assess the value loss of the marine ecosystem services function during the reclamation in Caofeidian sea field. Its influence on nearby sea feild ecosystem services function was also assessed. The result showed that the 10 500 hm2 reclamation project in Caofeidian sea field might cause an annual loss of marine ecosystem services value of 47.3567 million RMB yuan; among this, loss of biodiversity function value accounted for 46.52%, loss of climate regulation function value accounted for 20.92%, loss of air quality regulation function value accounted for 9.62%, and loss of food production value accounted for 8.98%. The influence Caofeidian reclamation project on its eastern sea field could lead to a loss of ecosystem services function value of 4.211 million RMB yuan each year, including the biodiversity function value with an annual loss of 12.4204 million RMB yuan, the food production function value of 4.5299 million RMB yuan, but the annual services of air and climate regulation functions value increased 9.9812 million RMB yuan and 4.5903 million RMB yuan, due to the increase of primary production functiona of phytoplankton community.
