摘要

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28%左右

单位面积增产30%

土地利用率提高40%。经济效益的增加

调动了群众坡改梯的积极性

试验期内试区辐射面积500hm

全市推广面积近5000hm

。

Abstract

It has been proved that.the capital construction on farmland with stress c}n the engineering of transforming dope into terrance

is the best way for the deveicpment of dryland farming in arenaceous hilly area.According to the technical and economical limats of dryland farming and the edurance of local pepople，the engineering must be designed maintaining the criterions of convenient，saving cost.quickly and small--scale.After five years resting in the arenaceous hilly area of Tai'an city.the authors point out that small-scale terraces can save 50 percent of the engineering work.and 40 percent of material cost，the control speed can be risen by almost one more times.Compared with the cultivated slopeland.the benefits of soil and water conservation can increase by more than 85 percent，the soil water content in flood season can increase by about 28 percent.the productivity increases by 30 percent.and the rate of land utililation increase by 40 percent.Thus.the economical benefit increase greatly and people's initiative is enhanced.During the testing，the influential area of testing district is 500hm2

and it is spread to area of 5 OOOhm2 in Tai'an municipality
