摘　　要：水平梯田是黄土丘陵沟壑区主要的坡面治理工程,也是主要的基本农田。水平梯田的田坎侧坡是水平梯田的重要组成部分,它不仅影响水平梯田的稳定,而且影响田坎占地的多少。采用现场调查与定位观测相结合的方法搜集典型流域田坎高与田坎侧坡资料,通过稳定统计分析,得出黄土丘陵沟壑区第一副区水平梯田(单式埂)田坎侧坡与田坎高的稳定性关系回归于二次多项式函数或指数函数,回归方程为二次多项式函数或指数函数的结论。Leveled terraced field is the main project of slope control and also the main capital farmland in the gullied rolling loess area.Lateral slope of field ridge is an important part of leveled terraced field.It effects not only the stabilization of leveled terraced fields,but also the size of occupied land.It collects the data of the height of ridges and lateral slope of field ridge of typical watersheds combining the methods of site survey and positioning observation.It obtains that the stability relationship of the height of ridges and lateral slope of field ridge of leveled terraced fields in the first sub-area of gullied rolling loess area regresses to quadratic multinomial function or exponential function and regression equation is the conclusion of quadratic multinomial function or exponential function
