Research on Land Use Change in Beijing Hanshiqiao Wetland Nature Reserve Using Remote Sensing and GIS

Taking the Landsat TM and ASTER images of Hanshiqiao wetland nature reserve in 1988, 1996 and 2004 as data source, based on the images interpretation by supervised classification, the land use changes during the period 1988 to 2004 were analyzed through land use dynamic degree. And then the driving forces of land use changes were analyzed based on natural and artificial factors. The results indicated that from 1988 to 2004, as the result of natural factors and human disturbances, the area of wetland shrunk, bringing the conversion from wetland to terrestrial land use types such as cultivated land and forest and grass land. Through the synthesis land use dynamic degree for the two sub-periods, the land use changes during the period 1996 to 2004 reduced comparing with that during the period 1988 to 1996. The management of Hanshiqiao wetland nature reserve must focus on wetland land use changes in future, so as to achieve effective conservation of the wetland. © 2011 Published by Elsevier Ltd.
