风化花岗片麻岩地区坡改梯试验结果表明：在当前山区农村经济现状和旱作农业耕作技术条件下，采取一次性修筑窄面土坎水平梯田治理坡耕地，在５°、１０°坡面上减流减沙效益平均分别为５７．９％、８９．８％，减少肥分流失分别为８９．３％、９５．９％，土壤容重平均降低４．０％，汛期土壤含水率平均提高２０．７％，土壤肥分平均提高４２．４％，大大改善了以土肥水为重要特征的生产条件，有效地促进了土地不断“升级”和生产率的提高，增产２２．４％～３７．３％；同时，隙地开发还可提高土地利用率４０％～５０％，堰埂利用还可增加经济收入。工程简易和费省效宏的治理措施，对群众有极大的吸引力，仅４年间，在北师试区就推广面积５００ｈｍ２，泰安市推广面积达５０００ｈｍ２。
The result of slope alteration test in weathered granite gneiss area shows that under the current situation of rural economy in the mountainous area and the technical conditions of dry farming, the horizontal ridge terrace with narrow ridge is used to control sloping farmland at 5 °, 10 ° slope On the surface, the benefits of reducing flow and reducing sediment were 57.9% and 89.8% on average respectively, and the reduction of fertilizer loss was 89.3% and 95.9% respectively. The average soil bulk density decreased 4.0% Increase soil fertility by 20.7% and increase soil fertility by 42.4% on average, which greatly improved the production conditions with soil-fertilizers as the key features and effectively promoted the continuous “upgrade” of land and productivity by 22.4% -37% .3%; the same time, the development of the gap can also increase land utilization 40% to 50%, weir can also increase the use of economic income. Project simple and cost-effective macro-control measures, the masses have a great attraction, only 4 years, in the North division to promote the area of 500hm2, Tai’an City, promotion area of 5000hm2.
