Impact of different spatial resolution image on landuse/cover

Abstract

In this paper, taken Landsat5/TM and SPOT5 images which were imaging in the close time as data source, the land-use map interpreted by Landsat5/TM and SPOT5 were obtained, respectively. To do some researches about LUCC and ecological effect, ecosystem services value was selected as ecological index. By analysis and contrast, it concluded that for the land use interpretation, different resolution images have little impact on the centralized distribution land use types, but it has great impact on scattered distribution land use types and washy land use types. Ecosystem services value evaluated by Landsat5/TM and SPOT5 showed that ecosystem services value obtained by SPOT5 image is lower than Landsat5/TM about 4.43*108 yuan. The difference was mainly caused by wetlands and grass. It hopes that the research can provide instructive suggestion for the future work. © 2011 Springer-Verlag Berlin Heidelberg.
