摘　　要：水平梯田是控制坡耕地水土流失和实现旱作区农业高产与稳产的根本措施之一,我国梯田建设已有几千年的历史,在分析和总结现有资料的基础上,对彭阳县水平梯田土壤水分的时空变化规律进行定点观测,分析,阐述梯田土壤水分季节变化的4个时期和垂直变化的3个层次变化规律。提出了不同时期梯田的水分情况为作物栽培提供依据。The level terraced field controls slope cultivated land soil erosion and realizes the drought agricultural high yield and one of the steady essential measures, the terraced fields construction of our country has already had a history of several thousand years, through analysing and summarizing existing materials, it was observed by fixed position the change rule of spacetime of the soil moisture of level terraced field in Pengyang county, and it analyses and explains rule that 4 levels and 3 periods of soil moisture seasonal variation and vertical changes for terraced fields, providing reference for crop cultivation.
