砂岩山丘区坡改梯规划设计及其效益

实践证明，进行以坡改梯为中心的农田基本建设是砂岩山区“旱农”开发的最佳途径。按照目前旱作农业开发的技术要求和经济、技术条件，以及群众自力更生承包治理的承受能力。坡改梯必须坚持施工方便、省工、省料、进度快的小型工程设计标准。通过在泰安市砂岩山丘区５年的试验。结果表明：小型梯田可省工５０％，节省材料费４０％，治理速度提高近１倍；较坡耕地水保效益提高７５％以上，保肥效益提高８５％以上，汛期土壤含水率增加

Design and Benefits of the Engineering Which Transforms the Slope Into Terrance in Aren}ceous Hilly Area

It is increasingly general to apply geographic information system in precess of planning soil and water conservation, But it still needs more study to use this new technique better.Taking Liuyie gully small watershed for an example, the author discusses the problems about how to plan soil and water conservation at small watershed with GIS.to make the program more canonical.scientifical and modernistic.and more fit for the characteristics and the needs of soil and water conservation.People then can get to the best objective of economical, ecological and social benefits.
