内蒙古农业大学沙漠治理学院 国际知名学术期刊 Science of The Total Environment 土壤 禁牧草地
2023/2/16
近日，内蒙古农业大学沙漠治理学院师生完成的论文“Mechanisms of grazing management impact on preferential water flow and infiltration patterns in a semi-arid grassland in northern China ”发表在《Science of The Total Environment》上。...
中国科学院东北地理与农业生态研究所农田分子生态学科组依托在黑土样带上建立的四个长期定位施肥试验，以及从哈尔滨周边农田采集的有机肥不同施用量和施用年限的土壤样品，采用高通量荧光定量PCR技术，解析出样品中ARGs多样性和丰度变化。发现施用禽畜粪便有机肥显著增加了土壤中ARGs和可移动遗传元件（MGEs）的数目和丰度。
2019年1月23日，美国哥伦比亚大学地球与环境工程系Julia K. Green教授团队在国际顶尖杂志Nature上在线发表了题为“Large influence of soil moisture on long-term terrestrial carbon uptake”的研究论文，该研究揭示了土壤湿度对长期的陆地碳吸收的影响。尽管陆地生物圈吸收了约25％人为排放的二氧化碳，但土地碳吸收率仍...
The top 2 inches of topsoil on all of Earth’s landmasses contains an infinitesimal fraction of the planet’s water — less than one-thousandth of a percent. Yet because of its position at the interface ...
Losses of soil carbon under global warming might equal U.S. emissions

For decades scientists have speculated that rising global temperatures might alter the ability of soils to store carbon, potentially releasing huge amounts of carbon into the atmosphere and triggering...
Soil moisture,snowpack data could help predict 'flash droughts'
Soil moisture snowpack data flash droughts
2016/11/4
New research suggests that "flash droughts" — like the one that unexpectedly gripped the Southern Rockies and Midwest in the summer of 2012 — could be predicted months in advance using soil moisture a...
IU study:During drought,dry air can stress plants more than dry soil
IU study drought dry air stress plants dry soil
2016/9/12
Newly published research by Indiana University scientists finds that low relative humidity in the atmosphere is a significant, growing and often under-appreciated cause of plant stress in hot, dry wea...

UD prof permafrost thawing vegetation carbon cycle
2016/3/11
“There is a lot of carbon frozen in the Arctic soil’s permafrost layer. If this all thaws out, prevailing thought is that the carbon in the soil could be released to the atmosphere and potentially acc...
University of Oregon geologists have seen ridges and valleys form in real time and — even though the work was a fast-forwarded operation done in a laboratory setting — they now have an idea of how cli...

美国 土壤水分 监测卫星
2015/2/2
在全球范围内，土壤保持着地球的一小部分水分。然而这些水分在水、碳和能量的循环过程中依然是一个至关重要的方面：它决定了一个地区对于干旱及洪涝的敏感程度，决定了植物能否很好地生长并吸收大气中的碳，同时还决定了地球的升温与冷却——这是暴风的一个关键驱动因素。然而在大多数情况下，土壤水分的监测一直依赖于稀疏设置在地面上的探测器。美国剑桥市麻省理工学院（MIT）水文学家Dara Entekhabi表示：“在...

Science There's something ancient the icebox
2014/5/13
Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything — vegetation, soil, and even the top layer of bedrock. So scientists were greatly surpri...
