Abstract:

Ecological vegetation features were studied using remote sensing and geographic information system
technology in Nanjing city and methods of research were discussed. In order to derive proper vegetation infor-
mation from TM image data, several means were tried in this study. Among them, the NDVI band was tested
with other bands and the result showed it was useful for lessening affection of hypsography of mountains on re-
motely sensed image data. The study showed that distribution state of vegetation in Nanjing city is extremely
un-even. Woodland of Zijin Mountain accounts for principal part of the total ecological vegetation. But the area
of ecological vegetation in flourishing central city is especially lacking comparatively. Spatial information tech-
nology, such as remote sensing and geographic information system, is effective in planning and extensive study-
ing ecological vegetation in city in order to provide scientific suggestion for improving ecological environment.
Based on the study, rational advice was brought forward for vegetation planning and construction in Nanjing
city.
