不同水土保持技术模式的坡耕地产流、产沙特征
Characteristics of Runoff and Sediment Yield on Sloping Farmland in Different Soil and Water Conservation Technology Modes
摘要
Abstract
Based on the problems of serious soil and water loss on the sloping farmland in the gentle hilly region of the northern of song-nen plaint during the year of 2009 and 2010, the comprehensive technique model of combining engineering technology and farming technology was first used by natural rainfall to study, the runoff plots included five kinds of soil and water conservation technology modes of mole drain, the combination of mole drain and subsurface pipe, furrow damming, the combination of mole drain and furrow damming, the combination of mole drain and subsurface pipe and furrow damming, and the five runoff plots were contrasted with control plot of conventional tillage in order to reveal the characteristics of runoff and sediment yield. The results were showed: (1)Comprehensive soil and water conservation technology mode had the best effect to delay runoff and sediment yield; (2)The order of runoff and sediment yield amount of different plots from big to small was furrow damming, mole drain, the combination of mole drain and subsurface pipe, the combination of mole drain and furrow damming, the combination of mole drain and subsurface pipe and furrow damming! (3) Compared to the control, comprehensive soil and water conservation technology mode were significantly better than the single technology modes on benefitting in runoff and sediment reduction, in which the combination of mole drain and furrow damming and the combination of mole drain and subsurface pipe and furrow damming had a better effect.关键词
