英文摘要	Central Asia located in the hinterland of the Eurasian Continent covers an area of around 4 million square kilometres. Far away from oceans, it generally has an arid and fragile eco-environment. Land cover change in arid regions is increasingly regarded as a sensitive indicator that echoes global change. Given a large area, the change of land cover in Central Asia is commonly considered to be induced by nature as well as human activities, especially after the collapse of the former Soviet Union occurred in the late 1980s. In this study, land cover change in Central Asia from 1990 to 2010 was investigated based on Landsat series and China Resources series satellite imagery. Classification of images at three eras (i.e., 1990, 2000 and 2010) relied on an object-oriented classification method, and was assessed based on fine resolution remote sensing data (e.g., Google Earth) and field investigation. Since the study region covers a vast areal extent and multiple images acquired at different times were utilized, a post-classification comparison method was adopted for detecting changes with less influence of image spectral difference. Analyses were conducted at the continental level scale. To validate the results, areas of land cover types retrieved from 30 m resolution remote sensing images were compared with statistics of other products.
