【摘要】 将渤海海域划分为辽东湾、渤海湾、莱州湾、渤海海峡和渤海中部五个部分,以海洋生态服务功能的物质生产、环境调节、文化娱乐、服务支持四大功能为基础,构建了水产品生产、提供基因资源、氧气生产和气候调节、污染物净化、生物控制、休闲娱乐、科研文化、初级生产、物种多样性维持等十项服务功能价值的评估方法。对渤海海域生态服务功能价值进行了定量评价。结果表明:渤海海域生态系统服务功能价值为558.85亿元,其中支持服务功能价值占32.84%,环境调节功能价值占29.69%,文化娱乐功能价值占27.74%;在空间分布上,渤海中部、辽东湾和渤海湾生态服务功能价值分别占到渤海海域生态服务功能总价值的38.47%,26.25%和20.85%,是渤海海域生态系统服务功能的组成主体;生物多样性维持功能价值和休闲娱乐功能价值是渤海海域生态服务功能价值两项最大的类型,生物多样性维持功能价值以渤海中部最大,其次为辽东湾、渤海湾,休闲娱乐功能价值以辽东湾最大,其次为渤海湾。更多还原

【Abstract】 In this paper,the Bohai Sea was divided into five parts,i.e.Liaodong Bay,Bohai Bay,Laizhou Bay,center of Bohai and Bohai strait.And ten types of ecosystem service function were established,including fish production,gene resource provision,O2 production,climate regulation,pollutant purification,biological control,leisure and entertainment,research and education,primary production and biodiversity conservation based on the four major functions,of material production,environmental,regulation,culture and entertainment,and service supporting.Assessment of ecosystem service values in the Bohai Sea was complished as follows.Value of ecosystem service in the Bohai Sea is 55.885 billion RMB,among which,the supporting service accounts for 32.84%,the regulation service account for 29.69%,and the cultural service for 27.74%.In the spatial pattern,Liaodong Bay,Bohai Bay and center of Bohai are the main body of the ecosystem service in the Bohai Sea,accounting for 26.25%,20.85% and 38.47% respectively of the total ecosystem service value in the Bohai Sea Biodiversity conservation service value is the biggest in the center of Bohai,next in the Bay Liaodong Bay,Bohai Bay,while leisure and entertainment is the biggest in the Liaodong Bay,and next in the Bohai Bay.更多还原
