Shuitu Baochi Xuebao, 2011 通过四川瀑布沟水电站消落区典型土壤磷释放室内模拟试验,研究淹水及干湿交替条件下消落区土壤性质变化情况以及土壤性质与磷释放之间的关系,以期为预防水库水体富营养化,水库消落区合理利用与科学制定管理对策提供参考。结果表明:淹水能够提高土壤活性氧化铁(Feox)含量,淹水风干后土壤Feox含量降低至淹水前的水平;淹水后Feox变化幅度为:旱地>水田>果园,紫色土>冲积土。土壤磷吸持饱和度(DPS)与无定形铁铝氧化物Alox密切相关;土壤最大吸磷量(Qm)淹水时最高增加至2 758.01 mg/kg ...

Shuitu Baochi Xuebao, 2020 土壤饱和导水率（Ks）是反映土壤入渗性能与土壤持水能力的重要参数，为探究流域尺度下土壤Ks的空间分布特征及影响因素，更好地掌握土壤水文过程与调节机理，选取晋西北黄土丘陵区朱家川流域横向梯度（上游、中游、下游）不同土地利用方式下的土壤（70个样点）为研究对象，采用定水头法测定土壤Ks，并获取样点地形因子和其他土壤理化性质，通过建立土壤Ks偏最小二乘回归模型（PLSR），分析影响土壤Ks空间分布格局的主要因素。结果表明：（1）除土壤容重和砂粒含量为弱变异外，区域土壤理化性质其余因子均为中等变异 ...

Comparison of fertilizer-effect models on winter wheat response to nitrogen and phosphorus fertilizers in saline soils in the Yellow River Delta [PDF]
, 2017 通过大田试验, 研究了黄河三角洲盐碱土地区冬小麦合适的肥料效应模型。在冬小麦生长季设置4种不同的氮磷肥用量, 根据“3414”试验设计8 种不同的肥效试验处理, 以探讨线性加平台、一元二次、平方根和二元二次4 种不同模型的拟合效果。结果显示, 4 种肥料效应模型的拟合结果经检验都达到极显著水平 (P<0.01)。在一元肥料效应模型中, 氮磷一元二次模型拟合效果最好, 最高收益分别为7 448.3 元·hm-2 和7 357.7 元·hm-2 ...

萨拉乌苏河流域150 ka BP 以来的粒度旋回 [PDF]
, 2001 萨拉乌苏河流域米浪沟湾地层剖面150 ka BP 以来古流动砂丘砂与河湖相和古土壤在粒度上具有多次显著的粗细韵律交替变化, 粒度参数- M z、R、Sk、Kg 和SC/ D 亦随之响应为多波动峰谷交替的态势。同时, 粒度特征值- 5 5、5 16、5 25、5 50、5 75、5 84、5 95 相应地表现为非常有节奏地跳动。据此, 将米浪沟湾剖面划分为27 个粒度粗细沉积旋回, 并认为其是150 ka BP 以来在东亚冬夏古代季风交替影响下沙漠演变的一个颇为完整的气候- 地质过程记录。The ...

Integrative Conservation, Volume 4, Issue 3, Page 362-380, September 2025.Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.
