Abstract
In order to deepen the understanding of the spatial pattern of land use,with the support of geographic information technology and the fractal theory,the paper used the "the second national land use investigation data" database to calculate quantitatively the fractal dimension and stability index of land use types of Gaoling District of Xi'an in 2008 and 2015 respectively.The results showed that the fractal dimension of paddy field,irrigated land,garden,ditch,traffic land,urban land and rural residential reduced and stability index increased.The fractal dimension of forest land,facilities,agricultural land,industrial,mining and special land improved and stability index decreased.The fractal dimension and the stability index of river water,hydraulic construction,unused land remained the same.According to the present situation of the results,the reasons of land use types changed with time and space were analyzed,which provided some reference for regional land planning and rational utilization of land resources.关键词
