Ecological benefit assessment of urban vegetations by remote sensing and GIS

Abstract

Abstract: As an important part of the urban ecosystem, urban vegetation plays an important role in improving urban environmental quality. The assessment of ecological benefits of urban or regional vegetations can help us more properly plan urban green space pattern, optimize urban vegetation structure, and further strengthen ecological construction. Through the discussion of the relevant researches at home and abroad, it's indicated that remote sensing and GIScould help us better evaluate the ecological effect of urban vegetations. This article introduced the UEAmethod adopted by AMERICAN FORESTS and CITY green software working with Arc View 3.2,as to make the best use of remote sensing and GISin evaluating urban vegetation ecological effect quantitatively, and to promote sustainable development and ecological construction.

Key words: Urban vegetation, Ecological benefits, Remote sensing, GIS, Urban Ecosystem Analysis (UEA)
