Abstract:

The relief type zonal map is the basic data for the region land use and agriculture global planning. But the existed relief zone data of Beijing is not accordance with the latest land use map, while the scale of the relief data is too small. To these questions, through collected and summarized the historical relief zonal solutions, the relief types and zonal criterion of Beijing are determined. The precision digital elevation model （DEM） generated by 1： 10000 contour of the study area is used as the main data source, while the geology map is referred to define the boundary of relief zones. Then the relief zonal data are validated and locally adiusted with the 3-dimensional relief view generated by SPOT5 remote sensing image and DEM,while the zonal data are verified with the field survey. At last, the Beijing relief zonal data which have the accordant scale and reference frame with the latest land use map of study area is presented.
