The invention discloses an 
urban greening quantity digital map manufacturing and displaying method. The 
urban greening quantity digital map manufacturing and displaying method comprises the following steps: importing urban basic map data into a 
geographic information system to form an urban three-dimensional vector information module; separating spectral information pixels related to 
greening quantity in a 
satellite remote sensing image, acquiring characteristic data and plane quantity of different 
tree species, simulating three-dimensional quantity through the plane quantity to calculate the 
greening quantity, storing 
greening quantity pixel information in an image form, storing a greening quantity result in a data table form, and forming an 
urban greening quantity 
database; connecting the urban three-dimensional vector information module and the urban greening quantity 
database, establishing map 
layers with different attributes, superposing 
database information, and exporting an urban greening quantity digital map. According to the urban greening quantity digital map manufacturing and displaying method, the greening quantity data and the urban map are superposed in a digital map 
system, and visual dynamic inquiry and display of the greening quantity data is realized. The urban greening quantity digital map manufacturing and displaying method can be used in the fields of 
urban planning, landscape gardens and building designs, and is a practical method for aided design and 
urban construction decision-making management.
