摘  要:
采用野外分峁坡和沟坡调查、采样和测量,研究了不同土地利用类型下小流域坡沟系统土壤水分变化的规律及与土壤含盐量的相关关系。结果表明:(1)峁坡和沟坡降雨前与降雨后土体的体积含水量随土层垂直深度呈二项式变化规律。(2)峁坡和沟坡电导率随含水量的变化分别呈幂函数和二项式变化规律。

摘  要:
Based on the field investigation,soil sampling and measurement on slope gully system,changes of soil moisture distribution patterns of different land utilization types and its relations with soil salt were studtied.Results indicated that(1) before and after the rainfall event,binomial relation was existed between soil moisture content and soil depth;(2) power function and binomial relation was existed between soil moisture content and electricity conductivity on slope and gully respectively.
