The Yangtze River Delta Economic Zone, one of the strategies for regional economic development, is undergoing some delicate changes. Relevant parties pointed out that the eco-environmental protection in the Yangtze River Delta Economic Zone is in an urgent and complicated situation. For example, the systematic protection of the river basin is inadequate and the degradation of ecological functions is serious. It can be seen that under the background of the general idea of economic development, the strategy is changing from promoting economic growth in the past to a more protective one. As the Central Government pointed out, China should make full use of its resources and not engage in large-scale development.
