Abstract
In this paper, taken Landsat5/TM and SPOT5 image which was imaging in the close time as data source, the land-use map were obtained, respectively. In order to do some researches about LUCC and ecological effect, soil loss and landscape pattern metrics were selected as ecological index by corresponding counting methods. By analysis and contrast, it showed that soil loss obtained by Landsat5/TM and SPOT5 image has little difference, and the average soil erosion modulus are 181.54 t/(km2•a) and 190.17 t/(km2•a), respectively. The erosion area in different erosion classification does not appear distinct difference. By the landscape pattern metrics value, it showed that the difference of MSI, PAFRAC, CONTAG and SHDI in Landsat5/TM and SPOT5 is only between 0.07 and 0.3, and the difference of LPI and AI was higher than above 3 types of index. But in a word, there were no big difference for all the index.
