红壤、黄壤地带(中亚热带)是我国粮食及亚热带经济作物、经济林木的重要基地。贵州高原就在这个地带上,土壤以黄壤、红壤为主。地势西北高而东南低,东部和南部高原边坡为向湘、桂丘陵过渡的低山丘陵,北部高原边坡为向四川盆地过渡的中山峡谷,高原面因切割作用残留甚少。高原主体上有数量较多的山间盆地和宽谷平坝,是农业生产基地。沿 Red soil and yellow soil zone (middle subtropical zone) are important bases for China’s grain and subtropical cash crops and economic forests. Guizhou Plateau is in this zone, with yellow soil and red soil. The terrain is high in the northwest and low in the southeast. The slopes in the eastern and southern plateau are the hilly hills that transition to Xiang and Gui hills. The northern plateau slopes are the midsummer valleys that transition to the Sichuan Basin. There are few residues on the plateau. There are a large number of mountain basins and valleys in Pingba, which are agricultural production bases. along
