Paper Abstract

Ruoergai Conservation area belongs to the Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province. In recent decades, the wetland and grassland have degraded very seriously. In this paper, based on GIS spatial analysis techniques, we utilized the Landsat 7 ETM + images in 2007, 2009, and 2011, to extract the land use/land cover change in Ruoergai. Firstly, the images were enhanced, mosaicked, and subset. Secondly, the supervised and unsupervised classification method were used to derive the land use/land cover change information in Ruoergai. Finally, the land use / land cover change in Ruoergai was analyzed between 2007 and 2011 . Our results were listed below: (1)The area of water body and swamp in Ruoergai reduced by 52.346% between 2007 and 2011. (2)The area of grass land in Ruoergai decreased by 12.754% between 2007 and 2011. (3) The area of woodland in Ruoergai reduced by 3.224% between 2007 and 2011. (4) The area of bare land, cultivated land and construction land increased by 6.647% between 2007 and 2011.
