This is the first English-language text written by China's leading scientists documenting the history, principles, models and assessment of ecological agriculture in China and its integrated farming system. In twenty detailed chapters, the book covers all aspects of China's integrated farming system, including rotation, relay-intercropping and intercropping, polyaquaculture, mixed stands afforestation, agro-silviculture, intercropping for tree-medicinal herbs as well as cash and multiuse forests, phyto-animal systems, mountain ecosystems, wetland ecosystems, arid and semi-arid ecosystems, agro-industry complex ecological engineering, and multi-component and multi-step use of energy resources. The book's final chapters set forth a systematic design for an integrated farming system, instructions on analyzing and assessing integrated farming systems, and a perspective on recent trends, obstacles, and the future.
