Abstract: Biodiversity protection in agricultural landscaping should get more attention than ever before as an important component of the global biological diversity protection and as the basis for food security and ecosystem stability as well,although agricultural activities contribute greatly to the loss of the global biodiversity.General principles for biodiversity protection in agro-landscaping,which was considered complementarity between patterns and processes in landscape ecology,were brought forth,including identifying and prioritizing the hotspots in agro-landscaping,protecting or establishing natural or semi-natural habitats,diversifying the land use/cropping system,increasing the connectivity by connecting the remaining natural and semi-natural habitats or establishing ecological corridor,expanding the area of farmlands low in farming intensity,adopting wild-life friendly farming management practices,preserving key species and maintaining interrelations among species,controlling aggressive over-abundant invasive species.Finally,problems in practical application of the above mentioned principles are discussed.
