The Urban Space Expansion Analysis in Mountain Areas Based on GIS and RS

With the rapid development of city, many large and medium-sized cities sprawl in urban space,triggering a series of socio-economic issues related to land-use. Based on RS and GIS, selected Kunming as study area for its typical representation of Yunnan plateau mountain cities, used the method of spatial quadrant orientation analysis, obtained the number and structure of construction land expansion in specific direction of study area in period of two different years, and calculated the intensity index and fractal dimensions of the urban expansion. Finally, according to local conditions, spatial expansion variations features of Kunming were analyzed systematically.
