With the continuous development of the coastal economic belt, it has become the main area of China's economic development and shouldering the important mission of China's economic development and social construction. This paper mainly analyzes the economic development and environmental development of coastal areas, constructs an evaluation model for the coordinated development of coastal economic belt and environment, and analyzes the economic development and environmental coordination of six cities under the jurisdiction of coastal economic belt. The GM model is used to predict the development of the coastal urban economic belt, and the annual index matrix is obtained. The economic and environmental development of the coastal economic belt and the six cities involved are calculated through the coordination model, and the relative evaluation is given.
