不同水土保持措施对地表粗糙度及其变化的影响
Effects of Different Soil and Water Conservation Measures on Land Surface Roughness and Its Changes
摘要
Abstract
[Objective]To understand the mechanism of surface roughness change under different soil and water conservation measures,so as to guide the prevention of soil erosion in this area.[Method]Taking the slope runoff observation field of Erdaoling small watershed in the low hilly area of western Liaoning Province as the object,the influence factors of different soil and water conservation measures on surface rough-ness and its change were studied by using the positioning observation method.[Result]There were differences in surface roughness among vari-ous measures.After four rain events,the order of surface roughness of various measures remained CK>cultivation measures>engineering meas-ures>forestry measures.There were differences in surface roughness change rate among various measures,the surface roughness change rate of various measures was cultivation measures>CK>engineering measures>forestry measures.The surface roughness change rate of various meas-ures was significantly negatively correlated with soil clay content(P<0.01),the surface roughness change rate of CK and engineering meas-ures was significantly negatively correlated with soil bulk density(P<0.01),the surface roughness change rate of forestry measures was signif-icantly positively correlated with soil moisture content(P<0.05),and the surface roughness change rate of forestland measures was signifi-cantly positively correlated with soil organic matter content(P<0.05).[Conclusion]The vegetation coverage,the initial surface roughness formed during the construction process,and the soil physical and chemical properties were important factors affecting the surface roughness and its change rate under different soil and water conservation measures.关键词
