摘　　要：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。The resources of sloping farmland,proportion of terrace and sloping farmland and terrace per capita were analyzed and general layout of sloping farmland remediation in Gansu province was put forward.The results showed that the sloping farmlands in Gansu province mostly distribute in the Loess area and the main slope range is 25°.There are 482.12×103 hm2 of low-standard terrace,adding the unremediable sloping farmland.The area of remakeable and newly build standard terrace are 2309.54×103hm2 in all in Gansu province.Calculated by agricultural population,the sloping farmland per capita is 0.20hm2 and the terrace per capita is 0.11hm2.It has abundant spaces of slope-to-terrace in Gansu Province.
