Abstract

This paper analyses the spatial landscape pattern of the cultivated land patch of the of Dalian 1:10,000 land use database; discusses the relationship between the cultivated land patch slope grade and DEM scale; presents the cultivated land slope grade technical process of region through GIS and DEM, realizes the cultivated land slope grade extraction through GIS program automatically; calculates the field ridge coefficient and the cultivated land net area through the cultivated land slope grade, as well as the cultivated land net area provides a scientific basis for the cultivated land database of the Second Territory Investigation, provides the protection and the spatial decision support of the cultivated land and the ecological and environmental.
