降雨对干旱半干旱区湿地和农田土壤CO_2短期释放的影响
2017
Overview
本研究以巴音布鲁克湿地和农田灰漠土原状土为研究对象,进行原位模拟降雨试验,利用LI-8100土壤碳通量自动测量系统测定土壤的CO_2排放,研究了不同降雨量对土壤CO_2排放的影响。结果表明：降雨导致湿地土壤CO_2释放速率显著增加（P〈0.01）,而农田土壤无显著差异。在其含水量无明显差异下,湿地不同降雨处理组的CO_2排放量均大于农田组,湿地土壤CO_2日累积排放量降水10 mm组〉降水20 mm组〉对照组,土壤有机碳高的湿地土壤随降雨量增加,土壤短期碳损失高,而对低有机碳土壤（西北干旱区贫瘠土壤）短期碳损失影响不显著。降雨后农田土壤降水10 mm组CO_2排放与地表温度和5 cm地温相关性极显著（P〈0.01）,其他各处理均未呈现显著相关。说明在干旱半干旱区降雨量对土壤CO_2排放速率有着重要的影响。
