| 摘要: |
| 根据国际生态系统服务共同分类的标准，海洋生态系统服务分为三大类、10 亚类，结合GIS 技术与市场价格法、替代成本法、污染防治成本法等评估方法，对江门市海洋生态系统供给、调节、文化服务价值进行量化评估和空间分布特征分析。结果表明：（1）2022 年，江门市海洋生态系统服务总价值为 174.96 亿元，由 44.73％的供给服务、37.94％的调节服务和 17.33％的文化服务组成，单位面积服务价值为 358.53 万元 /km2；（2）近岸贝类养殖产业除提供食品供给外，还能够提供额外的气候调节和废弃物调节服务价值，约占海洋生态系统服务总价值的 9％ ；（3）生态系统服务价值空间分布密度从近岸到远海整体呈逐渐降低趋势，近岸区内生态系统服务价值主 要取决于养殖生产，近海区生态系统服务价值主要取决于初级生产力。研究认为，通过科学发展 近海海域生态养殖产业，合理开发利用海洋生态资源，可有效提升生态系统服务功能，实现生态 保护与资源利用的协同推进。 |

| Abstract: |
| Based on the Common International Classification of Ecosystem Services（CICES），marine ecosystem services were categorized into 3 major categories and 10 sub-categories. Integrating GIS technology with valuation methodologies including market price method，replacement cost method，and pollution prevention cost method， this study conducts a quantitative assessment and spatial distribution analysis of the provisioning，regulating，and cultural service values of marine ecosystems in Jiangmen City. The results showed that：（1）In 2022，the total marine ecosystem service value（MESV）of Jiangmen City reached 174.96×108 RMB，comprising 44.73％ provisioning services，37.94％ regulating services，and 17.33％ cultural services，with the unit MESV of 358.53×104 RMB/km2；（2）The nearshore shellfish aquaculture industry not only provides food supply but also delivers additional climate regulation and waste regulation service values，accounting for approximately 9％ of the total MESV；（3）The spatial distribution density of MESV generally shows a gradual decline from nearshore to offshore areas．Within nearshore zones，MESV primarily depends on aquaculture production，while in offshore areas，it is mainly determined by primary productivity．The study suggests that developing marine aquaculture in offshore areas and scientifically and rationally exploiting marine ecological resources can effectively enhance ecosystem service functions，thereby achieving the synergistic advancement of ecological conservation and resource utilization. |
