Abstract:In order to improve the function of modern zoos in protecting wild animals and popularizing science, Chengdu Zoo has transformed crane exhibition into 7 cages with different wetland landscapes by using vegetation, enrichment and wall paintings, based on principles of scientificity, safety, practicality and selectivity. The reconstructed cages can not only meet the needs of animals and improve the display effect, but also show popular science information such as different types of wetland and regional differences to the public. This work can provide reference for the ecological transformation of other urban zoos with limited space.
