It is very meaningful for making the most of soil moisture to probe into spatial distribution of slopeland soil moisture in the Loess Plateau. Soil samples were taken from eroded steep slopeland in loess hill region. Soil water content of a depth of 200 cm at 20 cm intervals was determined in the laboratory. The data were processed by SPSS (8.0) software. The results show that soil moisture of all soil layers but 180~200 cm are normally distributed. Soil water content on the steep slope is high in 0~20 cm s...
