| 摘要: |
| 以曹妃甸围填海工程为例, 采用直接市场法、影子工程法和替代花费法等构建了围填海工程的海洋生态系统服务功能损失的货币化评估模型与方法, 并采用对比分析法, 建立并探讨了曹妃甸围填海工程对周边海域生态服务功能影响的损失估算方法。结果表明: 曹妃甸围填海一期工程占用海域滩涂面积10 500 hm2, 由此每年造成海洋生态服务功能价值损失4 735.67 万元, 其中生物多样性维持功能损失占46.52%, 气候调节功能损失占20.92%, 空气质量调节功能损失占9.62%, 食品生产功能损失占8.98%。曹妃甸围填海工程导致其东部海域生态系统服务功能价值损失每年为421.10 万元, 其中生物多样性维持功能每年损失1 242.04 万元、食品生产功能每年损失452.99 万元, 而气候调节功能和空气质量调节功能因海洋浮游植物群落初级生产增加而出现功能增大, 每年服务功能价值分别增加998.12 万元和459.03 万元。表明曹妃甸大规模围填海工程不仅对围填所在海域海洋生态系统服务功能造成彻底毁灭, 也对围填周边海域海洋生态系统服务功能产生重要影响。 |

| Loss appraisal on the value of marine ecosystem services of the sea reclamation project for Caofeidian |
|

| Abstract: |
| 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. |
