Shuitu Baochi Xuebao, 2019 为揭示不同复垦年限和培肥措施对采煤塌陷区复垦土壤氮素转化特征影响，分别采用间歇淋洗好气培养法、室内恒温控湿好气培养法和硝酸盐消失法研究了5种培肥措施下复垦4，8年土壤矿化、硝化、反硝化作用规律。结果表明：随复垦年限增加，土壤的矿化量（Nt）和矿化势（N0）均有增加，但土壤矿化率（Nt/N）及矿化势占全氮的比例（N0/N）无明显变化；不同培肥措施下，复垦8年土壤生物有机肥配施化肥处理（MCFB）Nt、N0、Nt/N和N0/N分别较单施化肥处理（CF）提高65.22%，65.21%，60.42%和60.76%

Shuitu Baochi Xuebao, 2018 在济宁高潜水位矿区的充填复垦区内，分析完整复垦周期的土壤碳演变特征。通过从塌陷地（M1）、复垦年限为0，3年的复垦耕地（M2、M3）以及正常耕地（M4）采集土样并检测土壤全碳（TC）、有机碳（SOC）、有机碳密度（SOCD）、有机碳组分（WDOC、POC、MOC、LFOC、HFOC、MBC）及稳定性同位素（δ13C），研究不同复垦周期阶段下土壤碳空间特征的变化情况。研究表明：（1）塌陷地的TC、SOC、SOCD和各有机碳组分含量较低。经过复垦措施期后，SOCD在复垦当年就恢复到正常耕地的水平 ...

Shuitu Baochi Xuebao, 2011 为了分析矿区不同复垦条件下,复垦土地土壤中有效微量元素的的分布特征,采用实地试验与实验室分析相结合的方法,研究不同复垦时间和复垦措施条件下土壤铜(Cu)、铁(Fe)、锰(Mn)、锌(Zn)4种微量元素有效态含量的时空变化规律。结果表明,在复垦土地恢复过程中,不同的微量元素含量变化表现出了不同的特征;恢复时间的延长有利于土壤有效微量元素的恢复和增加;当土壤恢复时间超过8a以后,有效微量元素含量接近或超过自然状态下土壤中的含量。不同治理措施对土壤有效微量元素含量及其分布也有较大影响,覆土 ...
