摘要
本文利用多种不同比例尺的遥感图像，分析了陕北地区的地貌特征及其区域分异规律，将陕 北地区分为三个地貌区，即东部黄土基岩丘陵区、中部黄土丘陵区和西部风沙区；还分析了地貌 条件对农业生产的影响及地貌的区城变化所引起的农业生产布局的区域变化，在此基础上对陕北 地区的农业生产布局提出了初步的看法。
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.
