This paper puts forward the definition and connotation of urban reserved area, and analyzes the differences between urban reserved area, natural conservation, and urban landscaping.

As the natural ecosystem, urban natural reserved area is the last habitat for indigenous species, which is different from natural conservation and urban greening.
