Paper Abstract

Land use/cover change (LUCC) is one of the most important fields of study in global environmental change research. Decades of dynamic change of cropland caused by human activities is an important topic in LUCC research. Minqin is located in Gansu province in northwest China, where the landscape configuration is fragile. In recent years, the environmental problems such as vegetation destruction and desertification became more and more serious. And there was a huge change in Minqin's cropland, which is an important factor to the environmental change in this area. Through the integration of Geography Information System (GIS) and Remote Sensing (RS) technology, this paper figured out the dynamic changes of cropland in Minqin, with a source data of Landsat TM products in 1989, 2000, 2005 and 2008. The results showed that there was a tendency of cropland transferring from downriver to upriver, which was a consequence of the advance of desertification.
