Shuitu Baochi Xuebao, 2011 以沂蒙山区的棕壤为例,利用野外原位模拟降雨试验,在分析比较5种典型覆被土壤结构稳定性的基础上,探讨不同土地覆被土壤结构稳定性对侵蚀泥沙全氮(N)、全磷(P)流失的影响。结果表明,土壤结构稳定性以山楂园和侧柏林较好,金银花和荒草地次之,花生地最差。不同土地覆被类型泥沙全N、全P流失特征差异明显,泥沙流失率与其全N、全P流失参量间具有显著的相关关系。土壤结构稳定性通过调节侵蚀产沙进而影响泥沙中N、P的流失特征,山楂园等土壤结构稳定性较好,侵蚀过程中更多地选择性搬运粘粒及精细颗粒,致使泥沙全N ...

Shuitu Baochi Xuebao[目的] 为揭示喀斯特地区玉米坡耕地地表、壤中、地下3种独特的水文路径对坡度的响应。[方法] 以贵州省喀斯特玉米坡耕地为研究对象,采用人工模拟降雨试验方法,在相同降雨强度(60 mm/h)条件下,不同坡度(5°,10°,15°,20°,25°)对各水文路径产流产沙规律的影响。[结果] (1)地表产流产沙与坡度呈极显著正相关(p＜0.01),地表最大产流模数和最大输沙模数分别为0.18 L/(min·m2)、13.12 g/(min·m2),地表产沙在10~30 min由面蚀演变为细沟侵蚀。(2 ...
