Starr of FAO. Without their trust, encouragement and careful revision, it would have been impossible to finish this report. I would also like to thank all authors for their contributions. We have worked together in the People’s Republic of China in the field of agroecology for many years. It is this cooperation that has been an important factor in the development of agroecology in China.

Four organization levels of biodiversity are often recognized: genetic diversity, species diversity, ecosystem diversity and landscape diversity. Landscape diversity refers to the spatial arrangement patterns of different patches, corridors and matrix elements. Ecosystem diversity refers to the structural arrangements of different primary producers, secondary producers and decomposers, including plants, animals and microorganisms with their environmental
