| 摘 要： | 针对松嫩平原北部丘陵漫岗区坡耕地存在的干旱与水土流失并存的问题,选取了垄向区田、鼠道、鼠道+暗管、鼠道+垄向区田、鼠道+暗管+垄向区田、常规耕作等6种水土保持技术模式,研究了土壤水分变化特征。结果表明,从整体上看,不同水土保持技术模式0～100cm土层土壤储水量与时段降雨量变化趋势一致,土壤储水量大小的技术模式依次为,鼠道+暗管+垄向区田>鼠道+垄向区田>垄向区田>鼠道+暗管>鼠道>常规耕作。各水土保持技术模式的总蒸散量大小依次为:鼠道+暗管+垄向区田>鼠道+垄向区田>鼠道+暗管>鼠道>垄向区田>常规耕作。研究结果为松嫩平原北部丘陵漫岗区坡耕地水土保持技术模式的合理选择提供依据。

| Abstract: | Based on the problems of draught and soil and water loss on the sloping farmland in the gentle hilly region of the northern of Song-nen Plain,six technology modes of 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,conventional tillage were selected.The paper studied on the variation characteristics of soil moisture.The results showed that the soil water storage in different soil and water conservation technology modes changed same trend as hourly precipitation on the whole.The order of soil water storage from big to small was the combination of mole drain and subsurface pipe and furrow damming,the combination of mole drain and furrow damming,furrow damming,the combination of mole drain and subsurface pipe,mole drain,conventional tillage.The order of total evapotranspiration in different soil and water conservation technology modes from big to small was the combination of mole drain and subsurface pipe and furrow damming,the combination of mole drain and furrow damming,the combination of mole drain and subsurface pipe,mole drain,furrow damming,conventional tillage.The research results can provide reference for reasonable selection of soil and water conservation technology mode in the gentle hilly region of the northern of Song-nen Plain. |
