【科技报道】研究:在工厂附近种植树木有助于减少污染 Study 本站原创 更新时间: 2019-11-30         

New research suggests that planting trees and other plants near factories could reduce pollution by almost one-third.

The addition of plant life may even cost less and be more effective than technology designed to cut pollution, a new study found. The findings were reportedin the publication Environmental Science & Technology.

最新研究表明,在工厂附近种植树木和其他植物可以减少近三分之一的污染。

一项新的研究发现,与旨在减少污染的技术相比,增加植物寿命甚至可能花费更少,更有效。 研究结果发表在出版物《环境科学与技术》上。


The lead author of the study was Bhavik Bakshi. He is a professor of chemical and biomolecular engineering at The Ohio State University in Columbus, Ohio.


Bakshi and other researchers collected data about air pollution and plant life in 48 of the 50 American states. They studied public records from every state other than Alaska and Hawaii.


该研究的主要作者是Bhavik Bakshi。 他是俄亥俄州哥伦布市的俄亥俄州立大学的化学和生物分子工程教授。

Bakshi和其他研究人员收集了美国50个州中48个州的空气污染和植物生命数据。 他们研究了除阿拉斯加和夏威夷以外的每个州的公共记录。

The researchers knew that trees and plants are already capturing large amounts of harmful emissions from the air. So they attempted to find out whether new vegetation could lessen air pollution's effects.


The study attempted to show how this vegetation could reduce the most common pollutants from industrial areas, including the production of energy from coal, oil and gas.


研究人员知道树木和植物已经从空气中捕获了大量有害排放物。 因此,他们试图找出新的植被是否可以减轻空气污染的影响。

该研究试图说明这种植被如何减少工业领域最常见的污染物,包括煤炭、石油和天然气的能源生产。


The researchers found that restoring vegetation to land cover, where possible, could cut air pollutant levels an average of 27 percent in the areas studied. They also found that in 75 percent of the areas, it would cost less to use plants and trees to reduce air pollution than to add new air cleaning technology.


研究人员发现,在可能的情况下,将植被恢复为土地覆盖可以在所研究的地区平均减少27%的空气污染物水平。 他们还发现,在75%的地区,使用植物和树木减少空气污染的成本要比添加新的空气净化技术的成本低。


"The fact is that traditionally, especially as engineers, we don't think about nature," Bakshi said in a statement. "We just focus on putting technology into everything."

People seeking to solve air pollution problems "need to start looking at nature and learning from it and respecting it," Bakshi said. He added that nature-based methods could result in "win-win" solutions that save money and are better for the environment.


巴克希在一份声明中说:“事实是,传统上,尤其是作为工程师,我们不会考虑自然。” “我们只是专注于将技术融入一切。”

寻求解决空气污染问题的人们“需要开始关注自然,向自然学习并尊重自然,”巴克西说。 他补充说,基于自然的方法可能会导致“双赢”的解决方案,从而节省成本并更有利于环境。


The study found that in most cases, less money would be spent creating vegetation solutions than building and operating air cleaning equipment. It found that only one piece of equipment was estimated to be more cost effective than trees and plants. That device is an industrial boiler.

The research suggested that in manufacturing, both natural solutions and technology could offer cost savings, depending on the kind of factory.


研究发现,在大多数情况下,与建造和运行空气净化设备相比,花在建立植被解决方案上的钱更少。 结果发现,据估计只有一种设备比树木和植物更具成本效益。 该设备是工业锅炉。

研究表明,在制造过程中,自然解决方案和技术都可以节省成本,具体取决于工厂的种类。


The study did not identify which kinds of trees or plants would be best at reducing air pollution. But Bakshi said the kind of vegetation likely would make a difference in air quality and that further study is needed.


The researchers predicted that the addition of trees and plants could help lower air pollution levels in both cities and rural areas. However, success rates would differ widely depending on how much land was available and current air quality levels.


这项研究没有发现哪种树木或植物最能减少空气污染。 但巴克西说,这种植被可能会改变空气质量,需要进一步研究。

研究人员预测,增加树木和植物可以帮助降低城市和农村地区的空气污染水平。 但是,成功率会因可用土地数量和当前空气质量水平而有很大差异。
