This book focuses on port collaborative operation, an important emerging topic in the port and shipping industry, and deeply analyzes the high-quality collaborative mechanism of port groups from the perspectives of port groups’ supply chain cooperative operation mechanism, port groups’ logistics network optimization, port groups’ collaborative scheduling optimization of resources, etc. Based on the combination of qualitative and quantitative analysis on China’s cases, this book makes comprehensive use of game theory, network optimization, multi-dimensional resource cooperative scheduling optimization, and other theories and methods, and promotes the update and innovation of current research methods in related research areas. The feasible policy insights for optimization of port groups’ collaborative operation are suggested at the end of book, which will help with the improvement of economic, environmental, and social benefits of port groups, and promote the port industry’s innovation, upgrading, and transformation. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content. The present version has been revised technically and linguistically by the authors in collaboration with a professional translator.

With the rapid development of Chinese urbanization in the 21st century, "urban diseases" become more serious, mainly manifested in water environmental pollution, urban flooding, water shortage, and deterioration of water ecology. It is necessary to establish a modern rainwater management system, scientifically solve the problem of excess urban rainwater and to improve water environment quality. Improvement of water environment quality is conducive to the ecological function of a sponge city. Sponge city construction has contributed to control non-point source pollution. Sponge systems cause the stagnation and purification of rainwater runoff, which is an important guarantee for water environment quality. This monograph summarizes theories and practices of the integrated water environment treatment in Chongqing, a typical representative mountainous city in the Three Gorges Reservoir Region. Based on the mountainous terrain and unique water environment characteristics in the Three Gorges Reservoir Region, the monograph analyzes measures and difficulties in the basin water environment integrated treatment. Moreover, the monograph makes suggestions for risk management amid drainage systems during the COVID-19 epidemic.
