- Abstract:
-
The typical site preparation engineering of drought resistance afforestation which were spread and application in ecological conservation of hilly region of southern Ningxia were made as a study object.And the rainfall-harvesting effect was learned in this paper.The results showed that: site preparation engineering of "88542" mode were effective in improving soil moisture conditions,especially on the 0-60cm soil layer.The effect of engineering measures was different with the terrain changing.With the slope of the top-down change,the increase rate of soil moisture of "88542" mode was higher than the rainfall-harvesting slope.And the increase rate of soil moisture was increasing along with slope length.The effect of rainfall-harvesting of engineering measures has no significant difference with the slope aspect.The effect of engineering measure and the slope length and gradient was positively correlated.In engineering design,the greater gradient,the corresponding rainfall-harvesting slope to shorten the length of the slope,on the contrary,the rainfall-harvesting slope to increase length of the slope.
