摘　　要：1985年以来,固原县结合小流域综合治理,开展了隔坡梯田模式研究。截至2001年底,固原县共完成隔坡梯田1 000 hm2,隔坡种草2 000 hm2。据调查,隔坡梯田较同类地区连台梯田粮食产量增加750 kg/hm2,较同类地区坡耕地粮食产量增加1 500 kg/hm2;实施隔坡梯田模式与常规建设梯田、造林、种草相比,单位面积投资减少30％,节省劳力50％,介绍了该模式的适用范围及建设内容。Since 1985, Guyuan County has conducted a study on terraced fields with slope with the combination of comprehensive management of small watersheds. By the end of 2001, Guyuan County has constructed 1 000 hm2 terraced fields with slope and 2 000 hm2 grasses with slope. According to the survey that the grain output of terraced fields with slope is 750 kg/ hm2 more than that of normal terraced fields in the same region and 1 500 kg/ hm2 more than that of sloped land of the same region. Comparing with the normal terraced fields, afforestation and planted grasses, the unit area investment of terraced fields with slope mode can reduce 30% and save labour 50%. The paper introduces the applicable range and building contents of the mode.
