对甘肃省坡耕地进行类型区划分,并对各类型区坡耕地资源量、梯田化程度以及农业人口人均坡耕地(梯田)等指标进行系统研究,提出甘肃省坡耕地整治总体布局。结果表明:甘肃省坡耕地以<25°的坡度范围为主,主要分布在黄土区。全省现有低标准梯田面积482.12×103hm2,加上未经整治的坡耕地,共有可经改造和新修标准梯田面积2309.54×103hm2。按农业人口计算,甘肃省人均坡耕地面积0.20hm2/人,人均梯田面积0.11hm2/人,有较为丰富的坡改梯空间。
Slope cultivated land in Gansu Province was divided into different types and the slope resources of cultivated land, the degree of terraformization and the per capita cultivated land (terraced fields) of agricultural population were systematically studied. The overall layout of slope farmland in Gansu Province was proposed. The results show that the sloping fields in Gansu Province are dominated by the slope of <25 ° and are mainly distributed in the loess area. The existing low standard terrace area of 482.12 × 103hm2 in the province, together with the non-remediation slope farmland, can be modified and newly renovated standard terraced area of 2309.54 × 103hm2. According to the calculation of agricultural population, per capita cultivated land area of Gansu Province is 0.20hm2 / person, and the per capita terraced area is 0.11hm2 / person.
