Method for determining ecological planning green area of urban and rural areas

The invention discloses a method for measuring green area of a targeted area. The method comprises the following steps of: S100, dividing plants in a targeted area into plants of different plant life forms, and taking a plurality of pre-determined plants as the representative plants of different plant life forms in one to one correspondence; S200, calculating the first green area of the pre-determined plant of each plant life form; and S300, summing all first green areas obtained in S200 to obtain the green area of the targeted area. By the method for measuring the green area of the targeted area, the biomass, ecological efficiency and ecological functions of green areas, which can generate actual effects, in the targeted area can be shown by a green area algorithmic model.
