Fish-scale pit is one of the soil and water control measures in the slope

and it is also a kind of slope afforestation site preparation methods.Due to its simple construction

storing surface runoff

the effect of maintaining soil and water

and promoting the growth of trees is relatively remarkable

it is widely application.In order to study soil moisture of fish-scale pits of different specifications by using fixed-point monitoring methods

soil moisture of fish-scale pits of four specifications in the Loess Plateau region of Northern Shaanxi Province was studied.Results showed that different specifications had a significant impact on soil moisture content.In terms of soil water on semi-sunny steep slope and extremely steep slope

specifications may be ranked in the descendant order of middle

large

small

smaller and contrast

in terms of soil water on semi-shady gentle slope and shady gentle slope

in the descendant order of large

middle

small

smaller and contrast.
