| Abstract: | Based on the interpreted Landsat-TM image data in 1980s,1900 and 2009,By the support of the 3S technology we analyzed characteristics of landscape patterns in Ejin natural oasis,Seven types of land use were identified:woodland,bush,grassland,water,cultivated land,settlement place and desert.Using GIS analysis tools,various types of land distribution and transfer trend and amplitude were analyzed from two aspects by using 25 years Ejin oasis LUCC and landscape pattern.The results showed that various types of... |
