Based on the GIS and aerial images of 2003a,this paper studies the spatial pattern of urban green landscape of Shanghai via landscape ecological theory.The green landscape was consists of several kinds according to landscape type and patch size.The spatial database of green landscape was built in MYSQL.The research area was divided into eight units.General distribution characters of urban green landscape was discussed at the level of landscape patch,landscape type and mosaic based on the theories of landscape ecological and spatial analysis.Several ecological indices of landscape,such as patches number,standard deviation of area,average area,fragmentation index and so on,was selected to research the quantitative characters of mosaic structure of urban green landscape.The main purpose is to reveal the spatial and temporal characteristics of urban green landscape during urban expansion and to provide decisions supporting for urban developing,managing and to solve urban ecological and environmental problems.
