松土对坡耕地产流产沙的影响研究
Scarification influence on runoff and sediment yield in the hilly land research
摘要
Abstract
[Objective]In order to study the different slope digging location and digging depth combination treatment effect on slope runoff and sediment yield.[Method] This experiment adopts the method of artificial rainfall,Fangshan prefecture in Luliang city sand ditch station runoff plots.[Results]The results showed that the yield of farmland flow,sediment yield was associated with a significant slope,digging location,production flow was associated with a significant digging depth and sediment yield relationship with digging depth is not obvious.On the slope,production flow increases with the increase of the slope,Production flow and the relationship between the digging position for cultivating middle＜upper＜the lower,Production flow with the increase of the digging depth reduction;Sediment yield increases with the increase of the slope,based on the relationship between sediment yield and the digging position scarification central＜upper＜the lower.On the slope,the central than the upper and lower digging dirt reduce runoff yield 13.1％ ～16.1％ and 16.1％～31.6％,reduce sediment yield by 3.3％～3.3％ and 40.5％～53.1％.[Conclusion]Considering benefits to block sand and water and farmland farming requirements,sloping land clearing should choose the upper in the slope surface,and digging depth with 20 cm advisable.关键词
