等高耕作 - The paper analyzes the effect of three cultivation measures of contour cropping , manual excavation and manual hoeing to the reduction of run - off energy and erosion based on office artificial rainfall testing
摘要在室内人工降雨试验的基础上,分析了等高耕作、人工掏挖和人工锄耕3项耕作措施对径流能量的削减作用和减蚀作用。 - The outcomes show that cultivation measures have the reduction functions of run - off energy and slope sediment production , of which , the action of contour cropping is the maximum and the action is reduced along with the increase of rainfall intensity and surface gradient ; cultivation measures also have a certain correlation on the reduction functions of run - off energy and erosion , in the meanwhile of slope sediment production , it is effected by the factors of soil erosion resistance and scouring resistance
结果表明:耕作措施对径流能量及坡面产沙均具有削减作用,其中等高耕作的作用最大,随雨强和地面坡度的增大其作用减弱;耕作措施对径流能量的削减作用与减蚀作用之间具有一定的相关关系,但坡面产沙同时受土壤抗蚀、抗冲性等因素的影响。 - 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 %
在相同的降雨条件下,黄土高原沟壑区等高耕作与直线坡相比,可提高入渗67 ,人工掏挖可提高入渗41 ,人工锄耕可提高入渗29 ;黄土丘陵沟壑区等高耕作可提高入渗45 ,人工掏挖可提高入渗22 ,人工锄耕可提高入渗14 。并根据黄土高原超渗产流的概念和水量平衡方程,建立了不同水土保持耕作措施强化入渗速率模型。
