| Abstract: | In this paper the regional landform specialities and its distributive regularities are analysed by using remote sensing images. The nortern part of Shaanxi Province is divided into three geomorphological regions which are hill region of loess and rock in the east, hill region of loess in the middle and wind-drift sand region in the west. Geomorghological influence on conditions of agricultural production and the influence of its regional regularities on the distribution of agriculture are analysed. Tentative views of distribution of agriculture in northern part of Shaanxi Province are presented. |
