STUDIES IN URBAN GREEN ECOLOGY AND ESTABLISHMENT OF INFORMATION SYSTEM

摘要

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, threedimentional 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 information and environment by aerial remote sensing was put forward in this article.
