Vertical variations of soil moisture and total nitrogen in small catchment on Loess Plateau

, 2010
为了研究黄土高原土壤中水分及全氮垂直分布及变异情况,对陕北神木县六道沟小流域中苜蓿地、荒草地、农地、柠条地以及油松地5种不同植被类型下0～800cm土层中土壤含水率和土壤全氮进行了测定和分析。土壤含水率在垂直方向上呈现出干湿交替的层状分布。植被类型影响土壤水分含量的垂直剖面分布;各植被类型下相对高湿层和低湿层出现的深度不同;不同深度土层平均土壤含水率不同。农地及退耕荒草地土壤水分涵养较好,垂直方向上含水率变化较大;人工植被苜蓿、柠条消耗土壤水分较多,土壤含水率变化相对平缓 ...

川中丘陵区不同利用方式的土壤养分特征研究

Shuitu Baochi Xuebao, 2006
通过实地调查、土壤采样分析和数理统计结合的方法，对川中丘陵区5种土地利用方式（水田、旱地、菜地、林地和荒草地）的土壤养分状况进行对比分析，结果表明．土地利用方式对土壤有机质、全氮、全钾、全磷、碱解氮、速效钾和速效磷含量的影响达极显著（或显著）水平；在5种土地利用方式中．土壤有机质和全氮含量由高到低的顺序为：水田〉林地〉菜地〉旱地〉荒草地；土壤全钾和速效钾含量由高到低的顺序为：水田〉菜地〉旱地〉林地〉荒草地；土壤全磷含量由高到低的顺序为：菜地〉旱地〉林地〉水田〉荒草地。
