Abstract

The Loess positive and negative terrains (P-N terrains), which are widely distributed on the Loess Plateau, are discussed by introducing its characteristic, demarcation as well as extraction method from high-resolution Digital Elevation Models. P-N terrains of 48 geomorphological units in different parts of Shaanxi Loess Plateau are extracted accurately. Then 6 indicators for depicting the geomorphologic landscape and spatial configuration characteristic of P-N terrains are proposed. A continuous change of P-N terrains from south to north in Shaanxi Loess Plateau shows an obvious spatial difference of Loess landforms. The P-N terrains participant landform classification method increases validity of the result, especially in the Loess tableland, Loess tableland-ridge and the Loess low-hill area
