宁夏砂田不同砾石覆盖厚度土壤入渗过程及模型分析

open access: yesShuitu Baochi Xuebao, 2017
以宁夏中部旱区砂田土壤为研究对象,通过对不同砾石覆盖厚度条件下砂田土壤水分入渗过程进行研究,采用一维垂直定水头入渗法,选取砾石覆盖厚度为影响因子,设置5个覆盖厚度(0,6,9,12,15 cm),观测湿润锋运移和入渗量变化规律,比较各处理土壤入渗特征,利用模型拟合土壤入渗过程。结果表明,砾石覆盖提高了土壤水分入渗能力,土壤湿润锋运移距离和入渗量明显增加。与CK相比,砾石覆盖厚度为6,9,12,15 cm时的累积入渗量分别增加了4.3%,11.8%,12.8%和17.1%,平均入渗率增加了25.8%,38.

微咸水入渗条件下碱土和盐土水盐运移特征分析

open access: yesShuitu Baochi Xuebao, 2008
通过微咸水入渗实验结果和入渗模型分析实验资料方法研究了碱土、盐土在微咸水入渗条件下土壤水盐运移特性。结果表明:当矿化度在一定范围,相同入渗时间内两种土壤的累积入渗量、湿润锋随入渗水矿化度的增加而增加;不同SAR的微咸水入渗对盐土、碱土入渗能力影响不大,特别是盐土。碱土的水分和盐分运移与入渗水矿化度均呈正相关关系,盐土则不然。

生物炭对矿区不同压实度土壤水分入渗和蒸发的影响

open access: yesShuitu Baochi Xuebao
目的探究水稻秸秆生物炭对矿区压实土壤水分入渗和蒸发特征的影响,为秸秆废弃物的资源化利用和矿区土壤修复提供依据。方法在模拟1.2、1.3、1.4、1.5、1.6 g/cm3(T1.2~T1.6)压实处理下,设置4种生物炭施量(0、2%、4%、6%)进行室内土柱模拟试验。结果1)不同施用量生物炭均减缓不同压实土壤湿润锋向下运移速率,土壤水分累积入渗量随生物炭施用量的增加呈先增加后减少趋势。2%施量处理均增加不同压实处理的累积入渗量,其中T1.2、T1.3、T1.5和T1.6时 ...
