苏打盐碱退化湿地淹水恢复对植物-土壤系统有机碳储量的影响

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 ...
