Application of DPSIR model in prediction of ecological sustainable development capacity in Bohai Sea

Abstract

The Bohai Sea is one of the three major marine economic zones in China, and its sustainable development capabilities have a key impact on economic development trends. Therefore, the DPSIR model is used to predict the ecological sustainability of the Bohai Sea. Through the DPSIR model, the development capability was predicted from five aspects (driving force, pressure, status, sustainable development impact, and response), and a prediction system was constructed. The analytic hierarchy process and entropy method are used to calculate the feature weights of the economic development data of Bohai Sea. The weights were inputted of the above indicators into the development capacity prediction model, and data training on the model was perform to complete the prediction of the sustainable development capacity of Bohai Sea. Finally, an empirical analysis of the Bohai Sea ecological sustainable development indicators is carried out. The study found that in recent years, the Bohai Rim provinces have experienced rapid economic growth, the people’s income level has increased significantly, the marine economy has continued to advance, and the driving subsystem forecast indicators have steadily increased. Optimizing the structure of the marine industry can improve the level of marine scientific and technological innovation and is an effective measure to improve the sustainable development of China’s Bohai Sea ecology.
