This analytical framework is applied to Bogor City considering its peculiarities of greenery open space existence and architectures. The research was conducted by spatial approach through CITYGreen 5.4 software to determine the ecological benefits of greenery open space, based on the trees canopy cover and non trees canopy cover to predict the economic value. CityGreen is a software tool developed by American Forest that helps people understand the value of trees to the local environment. The result showed that CITYGreen 5.4 software can be used to conduct complex analysis of ecosystem services and create easy to understand reports.The software calculate dollar benefits for the services provided by the trees and other greenery open space in absorbed such harmfull pollutants, carbon storage and sequestration, and reducing storm water volumes as natural flood control. The capacity of ecological benefit can still be improved to provide greater benefits in various ways.
