石坎水平梯田是石质山地、丘陵地区治理坡耕地,保持水土的一项重要措施。 石坎水平梯田填挖断面与土坎水平梯田填挖断面形式基本相同,但垒砌地坎的石方多是从地块外采运来的,因而石坎水平梯田田面净宽的中心线不是填、挖的分界线,田面净宽中的填方宽度大于挖方宽度,因此,在规划确定梯田田面毛宽或梯 Shikan horizontal terrace is stony mountainous, hilly areas slope farmland control, soil and water conservation is an important measure. Stone ridge horizontal terraced filling and excavation section and the ridge level terraces filling and digging section is basically the same form, but the ridge of the ridge is mostly taken from the outside of the plot, so the horizontal ridge of stone ridge horizontal surface of the net width of the centerline is not filled, Excavation of the dividing line, the net width of the field width of the fill is greater than the width of the excavation, therefore, planning to determine the terraced rice fields wide or ladder
