The construction of world-class Bay makes the marine ecology in Guangdong-Hong Kong-Macao Great Bay Area in risk. Based on the DPSIR index framework, Lotka-Volterra symbiosis model is applied to calculate symbiosis degree between coastal socio-economic system and marine ecosystem in 9 coastal cities. It is found that the marine ecological pressure in this area have not been reversed in recent 20 years. Most cities are in the stage that socio-economic development and marine ecological damage coexist. In Shenzhen, Guangzhou, Dongguan and Zhongshan, the damaged marine ecology has begun to restrain the further expansion of economy and society. The massive population agglomeration in Hong Kong, Macao and other places has caused serious marine ecological stress. It is urgent to improve the marine ecological security by cultivating ecological industrial system and industrial clusters, establishing a land-sea ecological restoration, promoting joint-protection and co-governance across different administrative regions.
世界级湾区的建设使粤港澳大湾区的海洋生态面临风险。基于 DPSIR 指标框架，应用洛特卡-沃尔泰拉共生模型来计算 9 个沿海城市沿海社会经济系统与海洋生态系统之间的共生程度。研究发现，该地区的海洋生态压力在过去 20 年中并未得到扭转。大多数城市都处于社会经济发展与海洋生态破坏并存的阶段。在深圳、广州、东莞和中山，受损的海洋生态已经开始限制经济和社会的进一步扩张。香港、澳门等地的大量人口聚集造成了严重的海洋生态压力。迫切需要通过培育生态产业体系和产业集群、建立陆海生态修复、促进不同行政区域的联合保护和共同治理来提高海洋生态安全。
