Changes of Wind Erosion and Wind Deposition on Surfaces of Newly Reclaimed Land in Cele County of Xinjiang Wei Autonomous Region
Pin-plugged method and meteorological observation method were adopted for analyzing wind erosion and wind deposition changes on surfaces of farmlands reclaimed in two years and in one year in Cele County of Xinjiang Wei Autonomous Region. The result indicates that wind deposition occurred in the range of 0-3 H (tree height) before and behind shelter belts along prevailing wind direction
the wind deposition volume upwind shelterbelt was more than that on the surface of downwind shelterbelt obviously
and on the surface of the middle part between two shelter belts it mainly showed wind erosion. Winter wheat planted in front of jujube tree seedlings could resist effectively wind erosion around jujube tree seedlings' roots in certain degree. On the surfaces of three natural underlying surfaces preserved with different vegetation coverage
the higher the vegetation coverage and plant height were
the stronger the resistance and wind deposition ability were. Because it was loose and bare surface without cultivation and there was no vegetation on newly reclaimed land
maximum wind erosion amount occurred in every same phase. Wind erosion and wind deposition changes not only have close relationship with vegetation coverage
shelter belts' structure
wind velocity and wind direction
but also have relationship with surface microtopography.
