在黃?土地區的8坡地上,不同耕作措施對小麥的增產效益按大到小的順序是:覆蓋覆膜等高溝壟直線坡。On the basis of analyzing factor ( soil particle composition, soil bulk density, water stable aggregate content, antecedent soil moisture, slope gradient, rain intensity, accumulation depth and soil crust, soil and water conservation tillage measures ) affecting soil infiltration rates, several relation models was obtained ; analyzed in detail different soil and water conservation tillage measures intensifying infiltration rates, while there have the same rainfall condition, the increasing infiltration rates of contour tillage and artificial digging and artificial hoeing in gully areas of loess plateau are 67 % and 41 % and 29 % ; the increasing infiltration rates in hilly areas of loess plateau is 45 % and 22 % and 14 %
在相同的降雨條件下,黃土高原溝壑區等高耕作與直線坡相比,可提高入滲67 ,人工掏挖可提高入滲41 ,人工鋤耕可提高入滲29 ;黃土丘陵溝壑區等高耕作可提高入滲45 ,人工掏挖可提高入滲22 ,人工鋤耕可提高入滲14 。並根據黃土高原超滲產流的概念和水量平衡方程,建立了不同水土保持耕作措施強化入滲速率模型。
