The invention discloses a measuring method and system based on urban function mixing degree, which includes the following steps: acquiring a POI data set, and classifying urban functions according totype information in the POI data set; drawing urban road line layer data, and extracting each road center point as a measuring unit of urban function mixing degree; extracting adjacent blocks of the road where each calculation unit is located, and constructing an urban function mixture degree calculation index of each calculation unit; establishing the function mixture degree calculation model, and calculates the urban function mixture degree for each calculation unit. A calculation system based on urban function mixture degree, which comprises: a POI data set acquisition module, a calculationunit division module, a calculation index construction module, and a calculation model establishment module. According to the measuring method and system based on urban function mixing degree, deep research is carried out on
