• 在污染土地中生长对树木有利?

    15-10-16 The very act of tolerating some forms of soil pollution may give trees an advantage in the natural world, says University of Montreal plant biologists. Their findings were published this week in BMC Plant Biology. High chemical tolerant plants can b...

  • 植物如何应对土壤中高浓度的盐分

    15-09-07 High salt in soil dramatically stresses plant biology and reduces the growth and yield of crops. Now researchers have found specific proteins that allow plants to grow better under salt stress, and may help breed future generations of more salt-tole...

  • 关注土壤安全

    15-05-11 A group of leading soil scientists, including the University of Delaware's Donald L. Sparks, has summarized the precarious state of the world's soil resources and the possible ramifications for human security in a paper published Thursday, May 7, in...

  • 土壤有助于控制核放射性

    15-03-25 Radiation suddenly contaminates the land your family has farmed and lived on for generations. Can soil play a role in protecting crops and human health? Research in Fukushima, Japan may lend an answer. On March 11, 2011, a magnitude 9.0 earthquake a...

  • 植被可防止水土流失

    15-01-22 Dust from soil erosion due to wind can affect human health, traffic, and, on a larger scale, climate. Investigators compared different models that quantify how the wind energy spreads over an herbaceous surface using data from the Sahel region of Af...

  • 伐木对土壤中碳平衡的影响是缓慢的

    14-12-03 Logging doesn't immediately jettison carbon stored in a forest's mineral soils into the atmosphere but triggers a gradual release that may contribute to climate change over decades, a Dartmouth College study finds. The results are the first evidence...

  • 加油时的小滴漏对公众健康有长期影响

    14-10-09 A new study suggests that drops of fuel spilled at gas stations -- which occur frequently with fill-ups -- could cumulatively be causing long-term environmental damage to soil and groundwater in residential areas in close proximity to the stations....

  • 太阳高能粒子改变了月球土壤的特性

    14-08-25 The moon appears to be a tranquil(安静的) place, but modeling done by University of New Hampshire and NASA scientists suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the s...

  • 阳光触发北极冻土中二氧化碳的析出

    14-08-25 The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide (CO2) after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, a new study -- funded by...

  • 灌木植入山地草原会改变土壤细菌构成

    14-03-13 Perched high on the bluffs(绝壁) of the big river valleys in the Midwest are some of the last remnants of never-farmed prairie grasslands. These patches, edged by forest, are slowly being taken over by shrubs. A recent University of Illinois study...
