Other Abstract

According to the wave type slope farmland morphological features and it’s characteristics of soil
and water loss,a wave type slope interception-precipitation-drainage technology was designed to solve the
soil erosion problems of the wave type slope farmland,and a method was put forward to calculate the rela⁃
tive parameters. Two plots (contrast plot and measure plot) were deployed in a small watershed, named
Northeast Gully, in PingQuan County of Hebei Province, and then the runoff and sand output were ob⁃
served. Observation results during 3 years showed that the soil erosions of wave type slope farmland were
mainly caused by several heavy rains,the average erosion reduction rate could still reach 98.37% in the
case of heavy rains as a result of using wave type slope interception-precipitation-drainage technology. Addi⁃
tionally,it is found that sub rainfall is an important factor affecting on the soil erosion in wave type slope
farmland through the analysis of rainfall data,and by the regulation of the wave type slope interception-pre⁃
cipitation-drainage measures,the runoff of the measure plot has been significantly reduced,and the correla⁃
tion coefficient between the measure plot runoff and sub rainfall decreased. Finally, the cost of the wave
type slope interception-precipitation-drainage technology is estimated at 30,075 yuan per hectare based on
the actual cost of building the runoff plots,only account for 49.60% of the rock mountain area stone dike
terrace cost,which has a good economic applicability. Therefore,the wave type slope interception-precipita⁃
tion-drainage technology can effectively prevent the soil and water loss in wave type slope farmland,which
can be used as a new technology for slope farmland erosion control.
