Within the ecological control line, land mostly exists in the form of mountain and water areas, with complicated landform, which is not only difficult for people to manage, but also brings much limitation to land utilization. Taking the mountains within ecological line of control in Huaide Village, Bao’an District, of Shenzhen for research area, generated DEM of 0.5 m resolution, using 1:10000 scale topographic maps based on ArcGIS technology. At the same time establishing dimensional space model of the research area, combining the Quickbird striograph of 0.6 m Spatial Resolution and DEM. Trough deep analysis of various terrain spatial data like slope and slope degrees, explore the method of using DEM to assist land use in ecological area, also establish Spatial Database to apply unity and efficient management. Results show that DEM is able to offer efficient technical means in field of land data spatial acquisition, land management and planning application. |
