The Research In Ecological Constraints Of China’s Three Big Urban Agglomeration Economy Development

Most developed countries of the world experienced treatment after pollution and spent a lot of time and wealth to adjust the relation between economy and environment. So when we develop the economy, the painful lesson of developed countries in environmental pollution must be kept in mind to avoid same mistakes. Economy should not be developed at the expense of the environment quality.Urban agglomeration where economy developed most rapidly is the concentration place of human activities, so it faces the most obvious ecological restrictions and the environment contradiction. This paper takes the three big urban agglomeration, Yangtze River Delta urban agglomeration, Pearl River Delta urban agglomeration and Bohai Sea urban agglomeration as objects and discusses the relation between ecological environment and economy from the land resource constraints, water resource constraints, energy constraints, and environmental constraints. What kind of price does the ecological environment pay when GDP of the three largest urban agglomerations are growing? What kind of ecological environment restriction will be faced if we only pursue pure material growth? What can we learn from the experience of developed countries? This essay focuses on answering the above questions.Introduction introduces related theories and research about the relation between economic development and ecological environment to provide the theoretical basis for the following research. The first chapter to the forth chapter discuss the land resource, water resource, energy and environmental constraints faced by the three urban agglomerations in the process of economic development. Chapter five analyses whether the three urban agglomerations can fit Environmental Kuznets Curve. Chapter six takes New York urban agglomeration as example and studies their measures in resolving ecological problems. The main conclusion is the points of coordinating economic development and ecological environment protection are optimizing the economic structure and improving energy efficiency.
