Shuitu Baochi Xuebao目的为探索苏打盐碱退化湿地淹水恢复后植物-土壤系统有机碳储量的变化规律。方法选择松嫩平原西部盐碱区域典型沼泽湿地退化多年地块（碱斑地、羊草地）和经淹水恢复的芦苇沼泽地为研究样地，基于样地植被地上-地下生物量、地下1 m土壤剖面理化性质指标的测定，分析探讨退化盐碱湿地恢复过程中土壤有机碳（soil organic carbon， SOC）质量分数及储量的变化规律及影响因子。结果恢复后芦苇湿地植被生物量为7 807.78 g/m2，碳库为1.90 kg/m2，较羊草地分别增加383.15%和216.67 ...

Shuitu Baochi Xuebao目的研究Al2（SO4）3联合有机物料对盐碱地氮转化机制的影响，揭示不同配施比例对土壤氮库的影响。方法以吉林省西部苏打盐碱土为研究对象，设置3个Al2（SO4）3梯度（占土重0.2%A0.2、占土重0.1%A0.1、占土重0%A0）与3个稻草梯度（占土重1%S1、占土重0.6%S0.6、占土重0%S0），分别测定施氮肥与不施氮肥2个条件下土壤NH4+-N、NO3--N、脲酶和蛋白酶活性。结果Al2（SO4）3引入提高平均净矿化速率和硝化速率，表现为A0.2S0>A0.1S0 ...
