人工藻结皮形成过程中表土非降雨型水分吸收的变化情况 [PDF]
, 2010 在干旱、半干旱地区,表土非降雨型水分吸收对于植物、生物结皮以及一些小型动物都起着非常重要的作用.本研究对库布齐沙漠中各种水分吸收类型进行了调查,并对人工结皮形成过程中水分吸收的变化进行了跟踪监测.结果发现,在实验区,从空气中吸收的水分占表土水分吸收量的25.07%~39.83%,其主要是通过水汽吸附机制进行.相比之下,表土从深层土壤吸收的水分更多,大约占到水分吸收量的60.17%~74.93%.人工结皮的形成促进了表土水分的吸收,但吸收水分的增加并非在接种后或结皮形成后立即表现出来,而是在结皮形成后 ...

Gradient distributions of nitrogen and organic carbon in the soils from inland to tidal flat in the Yellow River Delta [PDF]
, 2014 黄河三角洲是我国典型的通过黄河冲积泥沙填海造陆形成的近代沉积区。区域受到黄河冲积、沉积等自然过程和农业耕种熟化等人类活动的双重影响。本研究通过在黄河三角洲地区内陆到河口海湾不同距离采集典型土壤类型剖面发生层样品，探讨土壤有机碳、总氮等生源要素的空间分布规律，为阐明我国典型海岸带地区陆源碳、氮的输送及循环特征提供基础依据。研究结果表明，黄河三角洲内陆与河口地区呈现出完全不同的土壤碳、氮分布规律。表层土壤碳、氮含量在黄河沿岸及三角洲南部均表现出由陆向海逐级递减的空间分布特征 ...
