摘要
海洋生态系统服务价值对海洋资源开发和海洋综合管理具有重要的意义。研究应用联合国千年生态系统评估框架,构建了食品生产、原料生产、基因资源、氧气生产和气候调节、废弃物处理、生物控制、休闲娱乐、科研文化、初级生产以及物种多样性维持等10项服务价值的评估方法。对辽东湾、渤海湾和莱州湾进行了上述10项生态系统服务价值的评估,结果表明,三个海湾服务功能的总价值量为1 485.11×108元,单位面积价值为4.52元/(m2 a)。其中,辽东湾价值量最大,占三个海湾总价值量的56.7%,其次是莱州湾,占总价值量的23.3%,渤海湾最小,占总价值量的20%。各项服务中,食品生产的价值量最大,占总价值量的71.0%。食品生产、氧气生产和气候调节、初级生产这三项服务价值之间表现出显著相关性,主要是由于三项服务有着共同的初级生产者。研究结果可为相关管理部门制定生态补偿政策提供理论依据。
The value of marine ecosystem services plays an important role in marine resources development and marine management. In this research, we use the classification method of Millennium Ecosystem Assessment, which is to divide the ecosystem services into food production, gene resources provision, oxygen production and climate regulation, waste disposal, biological control, leisure and recreation, scientific search and culture, primary production, biodiversity and habit provision. The result shows that the total economic values of 10 services of the marine ecosystem services of Liaodong Gulf, Bohai Gulf and Laizhou Gulf is RMB 14851.1 million yuan. Among them, Liaodong Gulf has the largest value, followed by Laizhou Gulf and Bohai Gulf, accounting for 56.7%, 23.3% and 20%. Food production has the largest value in each ecosystem service, accounting for 71%. It appears high relativity among the food production, oxygen production and climate regulation and primary production, because they depend on the same primary production phytoplankton and benthic algae. The valuation of marine ecosystem services in this study would help government officials to establish the policy of ecosystem compensation.
