东北黑土区不同坡段等间距植物篱减流减沙特征

Shuitu Baochi Xuebao, 2019
植物篱作为一种有效的水土保持措施，带间距是其配置的关键参数，当前大部分植物篱布设时采用等间距设计，但不同坡段等间距植物篱的作用效果如何尚不明确。以东北黑土区不同坡段等间距植物篱为研究对象，通过含沙径流冲刷试验，模拟不同坡段等间距植物篱在坡度5°，雨强100 mm/h降雨条件下的产流产沙过程。结果表明：与裸地对照相比，各坡段植物篱能够阻延坡面径流，且随坡段的下移，滞后时间逐渐缩短）各坡段植物篱产流、产沙速率在时间尺度上表现基本一致，在上、中坡段植物篱坡面相对平稳，下坡段植物篱坡面后期呈明显波动 ...

坡耕地黑土活性有机碳空间分布及生物有效性

Shuitu Baochi Xuebao, 2006
以一东北黑土区典型漫岗坡耕地为研究对象，测定不同侵蚀程度地形部位的活性碳组分，以分析土壤侵蚀对活性碳组分的影响以及沉积区侵蚀碳的归宿。研究结果表明：各地形部位表层黑土（0～20cm）水溶性有机碳（WSOC）含量介于14．6～20．0mg／kg之间，低于总SOC含量的0．15％WSOC在沿坡迁移的同时，向下淋溶也很显著。MBC含量为121．5～583．6mg／kg，占总SOC的1．0%～4．7％。Min—C变化范围为52．8～115．3mg／kg，土壤Min-C差异主要集中在表层 ...
