This book presents an in-depth study on and summary of the current practice and theories for the construction of eco-cities in China in the context of the country's rapid urbanization. It argues that by 2020, 60% of China's population will live in cities. And the evolution from "green cities" to "eco- cities", and subsequently to "smart cities" is crucial to China's sustainable development. The book presents a feasible and objective quantitative evaluation system for the sustainable and healthy development of eco-cities. It summarizes the Chinese experience in building eco- cities as the coordinated development of economy, society, resources and environment, with the goal being "to make cities inclusive, safe, resilient and sustainable". This is essential to achieving a number of the United Nations' Sustainable Development Goals. In addition, the book defines the current stage of development Chinese cities have reached in terms of ecological construction, and offers guidance on selecting suitable urban ecological construction modes and improvement approaches. It provides a valuable reference source and guidebook for research on and the practice of eco-city construction. Accordingly, it will help other countries around the world, especially the developing countries, to benefit from China's successful experience.
