GIS-based Analysis of Relationship Between Land Use and Topography--A Case Study of Huangling County,Shaanxi Province
slope degree and aspect) and land use in Huangling County
Shaanxi Province were extracted from DEM and land use map of the county with ArcGIS software.The distribution of various land use types regarding different elevations
slope degrees and slope aspects was analyzed by overlapping the topographic features and land use information.The results showed that most farmlands
garden lands and residential lands were located in the areas with slope degree lower than 3° and lower altitude.In contrast
forest lands were concentrated in the areas with slopes degree greater than 8° and elevations lower than 1 000 m.From the perspective of slope aspect
the flat lands have been commonly used while the lands with other slope aspects were used to various extents.
