Description :
In this study, the AA. reconstructed the former landscape structure and elucidated the changes in landscape patterns during a period of about 15 years. Two sets of maps were used : a landsat-5 TM image (1987) and landsat-7 ETM image (2002). The frequency index, landscape diversity index and landscape fragmentation index were calculated for analyses. The AA. combined the quantitative calculations of the landscape structure and GIS spatial analysis to analyze the impacts of human activities on agricultural landscape.
