Discussion on Large Scale Digitized Mapping of Loess Landform

ZHAO Peng-quan1,SUN Chang-min2(1.Inner Mongolia Institute of Surveying and Mapping of Geology,Hohhot Inner Mongolia 010020,China;2.Inner Mongolia Sixth Institute of Survey and Development of Geology and Mineral Resources,Hailar Inner Mongolia 021008,China)  
This article analyzes loess landform type,discusses the terrain feature and the expression method of loess landform in digitized mapping.The article considers that loess landform ravine is the emphases and difficulty of large scale digitized mapping,and that would distinguish the ravine types,according to the scale of mapping and the contour interval to determine synthesis accept and reject principia and expression method,and applies measuring instrument,traditional measuring notation and direction method of portrayal to enhance the precision of loess landform topographic map.
