Rainwater High Efficient Utilization Pattern in Slope Compound

TANG Xiao-juan1,JIN Yan-zhao1,GAO Jian-en2(1.Gansu Research Institute for Water Conservancy,Lanzhou 730000,China;2.Institute of Soil and Water Conservation,the Chinese Academy of Sciences and Ministry of Water Resources,Northwest Sci-tech University of Agriculture and Forestry,Yangling 712100,China)  
Some tests have been done to simulate manual rainfall runoff washout on slope compound,and to study on runoff adjustment effect under the condition of 2 kinds of rainwater intensity and 4 pieces of measures,to analysis runoff principal from runoff time,erosion and sediment amount.The preliminary experimental research results are shown as: Pater and PAM is a ideal measure due to minimal runoff and erosion comparison with the same slope antitheses,increased 93.02%,98.13%,repectively,the following measures are Pater and hole,as well as PAM and hole;Only runoff adjustment effect of hole on the slope is not evidence compare with the some slope antitheses;Slope almost barely effect to different compound measures,however,rainfall intensity's effect is completely prominent.Slope compound measures with soil and water conservation patterns have change the situation of micro-slope landform,and increased plant coverage,enlarged precipitation's infiltration speed and quantity,as well as played the theory instruction role to water resources effective utilization in Loess Plateau.
