Abstract 
The Urban Green Ecology Information System (UGEIS) given in this article is one of the 
most essential system about some special topics and functions in the urban GIS. It 
consists of four parts, namely two-dimensional greening overlay rate library,  three- 
dimentional green quantity information library, management information library of special 
greening areas and environmental information sub-library. The major means of setting up 
the system is the aerial remote sensing and computer technique and the major object is 
to research quantitatively the green ecology information and to analyse the relation 
between greening and environment. Specially the 3-D green biological quantity can be used 
to estimate the economic output of urban greening and to analyse the relation between the 
output and the social results. In short, from macroscope to microscope a basic means of 
researching the information of urban green ecology and the relation between the informa- 
tion and environment by aerial remote sensing was put forward in this article.
