Coexistence or Mutual Loss?

Abstract:
How to assess the health status of China’s coastal ecosystems and establish a comprehensive ocean observation plan to support the assessment of ecosystem health status are major scientific issues that urgently need to be addressed by the Chinese government and local coastal governments. Based on the Lotka-Volterra, a symbiosis model is applied to calculate symbiosis degree between the coastal socio-economic system and marine ecosystem in Beibu Gulf. It is found that the marine ecological pressure in Beibu Gulf has not been reversed in the past 20 years. Most cities are in the stage when socio-economic development and marine ecological damage coexist. We use the Lotka-Volterra model to discuss the dynamic process of the evolution and development of marine ecosystem and coastal socio-economic system in an environment of mutual influence. It is urgent to improve marine ecological security by cultivating ecological industrial system and industrial clusters, establishing a land-sea ecological restoration, and to promote joint protection and co-governance across different administrative regions.
