农用塑料薄膜会在田间降解成直径小于5 mm的微塑料颗粒，影响土壤理化性质和土壤微生物的生境，严重威胁土壤生态系统。目前，塑料薄膜节水保肥技术被广泛应用于盐碱土壤改良，然而由此产生的微塑料污染也随之而来。

日前，宁夏大学生态环境学院贺兰山学者李新荣老师在干旱荒漠生态系统生物结皮固氮酶响应增温和干旱方面取得了最新研究成果。该研究以中科院沙坡头沙漠试验研究站长期全球变化研究平台OTC（Open-top chamber）增温罩为依托，发现藻结皮和苔藓结皮固氮酶对温度的响应结果不同，低温条件可以增加藻结皮N的输入，而高温条件下则降低藻结皮和苔藓结皮的N输入。研究结果为干旱荒漠区土壤N循环过程及响应气候变化提...

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 ...

“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...
