Atlas analysis on land use spatial-temporal changes in Mianzhu city, China

In this study, land use data in the Mianzhu city, China are extracted from remote sensing data of 1970s, 1980s, 1995, 2000 and 2005 and land use atlas are established and analyzed using geo-information atlas theory. The results indicate that from the temporal series, farmland and unused land decrease and other lands increase during 1970s to 2005 except farmland increases and forest land reduces in sub-period of 1995 to 2000. From the spatial series, farmland convert to construction land in the nearby of town and unused land converting to forest land and grassland are in the northwest of Qingping. In arising/declining atlas, the largest expanding atlas is construction land, increasing by 11.11km², accounting for 65.66% in expanding atlas, mainly from farmland. And the largest shrinking atlas is farmland, reducing by 11.54km², accounting for 68.20% in shrinking atlas, mainly transforming to construction land and forest land.
