本区属中温带内陆干旱荒漠区。为青藏、蒙新二大高原的过渡地带。气候干燥,雨量稀少,走廊腹部年降水量自东向西由200毫米递减至40毫米。由于降水稀少,农田用水主要依赖祁连山雪水灌溉,三大内陆水系两岸川区可资掘井提灌,形成“绿洲灌溉农业”。境内土地总面积27.84万平方公里,占全省的61.4％,耕地面积1040余万亩,占全省耕地面积的20％左右,每农业人口,占有耕地3.21亩,其中可资灌溉的水地2.38亩。农区可分:1100—
The area belongs to the temperate inland arid desert area. For the Qinghai-Tibet Plateau, Mengxin two plateau transition zone. The climate is dry and rainfall is scarce. Annual precipitation in the abdomen of the corridor decreases from 200 millimeters to 40 millimeters from east to west. Due to scarce rainfall, farmland water mainly relies on snow water irrigation in Qilian Mountains, and three inland waterways can be tapped for irrigation and drainage in both sides of the Sichuan Basin to form “oasis irrigated agriculture.” The territory of the total area of 278,400 square kilometers of land, accounting for 61.4% of the province, more than 1040 acres of arable land, accounting for about 20% of the province’s arable land, agricultural population, possession of 3.21 acres of arable land, of which irrigated water 2.38 mu. Agricultural district can be divided into: 1100-
