分析深澳湾浅海养殖生态系统服务功能,运用《海洋生态资本评估技术导则》(GB/T28058-2011)对该生态系统的生态服务功能进行价值评估。结果表明:2011年深澳湾养殖生态系统服务功能主要分为:食品供给、原材料供给、氧气产生、气候调节、废弃物处理和科研服务。2011年深澳湾浅海养殖生态系统服务价值为7 959万元,平均单位海域面积的服务价值为598万元/km2。在评估的6项服务中,食品供给4976万元,占总服务价值的62.52%,突显了食品供给为养殖型海湾的主要服务功能。其次为原材料供给(1 933万元)、氧气产生(484万元)、气候调节(249万元)和科研服务(214万元),废弃物处理最低,为103万元。牡蛎和龙须菜所提供的服务价值占总服务价值的79%,表明龙须菜和牡蛎养殖在深澳湾浅海养殖生态系统服务中具有决定性作用,特别是龙须菜养殖对于维持和提升养殖生态系统的服务有重要意义。
The function of ecosystem service of shallow ecosystem in Shen’ao Bay was analyzed, and the value of ecological service function of the ecosystem was assessed using the Technical Guidelines for Marine Ecological Capital Assessment (GB / T28058-2011). The results showed that: 2011 Shenzhen deep Bay farming ecosystem services are mainly divided into: food supply, raw material supply, oxygen generation, climate regulation, waste disposal and scientific research services. In 2011, the service value of Sham Bay shallow-sea farming ecosystem services was RMB 75.90 million and the service value of the average unit sea area was 5.98 million yuan / km2. Among the six assessed services, the supply of food amounted to 49.76 million yuan, accounting for 62.52% of the total service value, highlighting the main service functions of food supply as a breeding bay. Followed by raw materials supply (19.33 million yuan), oxygen production (4.84 million yuan), climate regulation (2.49 million yuan) and scientific research services (2.14 million yuan) with the lowest wastes disposal at 1.03 million yuan. The service value provided by oysters and asparagus accounted for 79% of the total service value, indicating that asparagus and oyster farming play a decisive role in the deep-sea aquaculture ecosystem service in Shen’ao Bay. In particular, asparagus breeding is very important for maintaining and enhancing aquaculture Ecosystem services are important.
