| 摘 要： | 针对松嫩平原北部丘陵漫岗区坡耕地水土流失的严重性,利用2009,2010年2年时间在天然降雨条件下首次采用工程技术与耕作技术相结合的综合技术模式进行研究,径流小区包括鼠洞、鼠洞+暗管、垄向区田、鼠洞+垄向区田、鼠洞+暗管+垄向区田5种不同水土保持技术模式,并与对照小区常规进行对比进而揭示各小区的产流产沙特征.结果表明:(1)综合水土保持技术模式对产流产沙的延缓效果最好;(2)各小区的产流产沙量由大到小依次为:垄向区田、鼠洞、鼠洞+暗管、鼠洞+垄向区田和鼠洞+暗管+垄向区田.(3)与对照区相比,综合技术模式的臧流减沙效益明显优于单一的技术模式,其中鼠洞+暗管+垄向区田和鼠洞+垄向区田的效果最好.

| 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 plain,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... |
