| 摘 要： | 黄土高原地区气候类型多样、地貌特征复杂、水土流失严重,造成农业生产条件在区域上存在很大差异,因此,有必要对耕作制度进行分区,以指导该区农业生产发展。以热量(≥0℃积温)、水分(降水量、干燥度)、地貌等作为分区指标,以县(区)为基本单元,采用地理位置-地貌-水旱作-熟制的命名方法,将该区划分为10个耕作区,并描述了各区的自然与社会条件、作物类型、主要耕作方式及发展方向等。 |

| Abstract: | The Loess Plateau region has various climate types,complex geomorphological features and serious soil and water loss,which resulted in considerable differentiation of its agricultural production conditions in the region.It is essential to regionalize the cropping system to guide the development of agricultural production.The Loess Plateau region was divided into ten different farming areas by indices including of heat(≥0℃ accumulated temperature),moisture(precipitation,dryness),landforms,etc.based on the county unit.The naming type was integrated location-landforms-dry/irrigated farming-cropping system.The characteristics of each region,such as natural and social conditions,crop type,main farming methods and development direction,were described also. |
