中文摘要 | 长江上游坡耕地多,人均耕地少,人民生活贫困,水土流失严重。20 a来,"长治"工程在小流域治理中,按照"以防为主,防治结合,因地制宜,综合治理,重点突破,积极推进"的方针,以坡改梯为突破口,配套小型水利水保工程,将坡耕地集中连片改造为梯地,并配套较为完善的坡面水系工程和田间作业道路,大幅度提高了土地产出率和劳动生产率,增加了农民收入,促进了县域经济发展。坡改梯整治不仅治理了坡耕地的土壤流失,而且促进了侵蚀冲沟的逐渐消亡,有效地控制了水土流失。 |
英文摘要 | The upper Yangtze River is characterized as much steep slope farmland,small farmland per capita,serious soil-water loss and people living in poverty.For the past 20 years,in the small basin regulation of the major control engineering of soil and water conservation in upper and middle Yangtze River,in line with the principle of "prevention-oriented strategy,combination of prevention and control,taking measures to suit local conditions,comprehensive regulation,key point breakthrough,active promotion",taking slope land reformation to terrace as breakthrough point,we construct auxiliary water conservancy infrastructure,transform slope land to large terrace,which greatly improved the output ratio and labor productivity.The soil-water loss control increases the income of farmers and promotes the economic development in local areas.The slope land transformation to terrace not only controls soil-water loss but also promotes the extinction of erosion gully. |
