Urban habitat unit mapping refers to drawing the spatial distribution characteristics of habitat units to form a comprehensive information atlas that comprehensively covers the urban area and can identify the clear boundary between adjacent habitat units. Among them, the definition of habitat unit was first proposed by Dahl, that is, "any living space for animals and plants that can be delineated", also known as habitat. The division of habitat units follows the basic principles of typicality, minimum heterogeneity, reflecting the characteristics of ecological cells and ecological processes. Urban habitat unit mapping includes two methods: selective biotope mapping method and comprehensive biotope mapping method. Its goal is to distinguish the boundaries of urban habitat units and reveal the spatial distribution pattern of biological species within the boundaries and the relationship between them and the ecological environment gradient. At present, urban habitat unit mapping has become an important tool for urban spatial ecological planning and biodiversity conservation research. It is an effective way to apply original ecological environment data and biological information to urban natural protection and ecological space management decision-making.
