arirangnews2013.8.10---韩国农村振兴厅开发植物垫降温系统
Korean researchers have developed a new way to cool down cities .... without the need for energy-sapping air conditioners.
The all-natural system utilizes plant-based mats to ensure cooler and greener urban centers.
Kim Minji shows us how this eco-friendly method works. It's sizzling here in the heart of Seoul, with the scorching midday sun looming overhead. The stubborn heat wave continues to make for hot and stuffy conditions, especially in urban areas.
The heat emanating from cement sidewalks can reach up to 39 degrees Celsius, while the air temperature around vehicles can rise to a blistering 42 degrees.
But Mother Nature knows how to stay cool, as mercury readings are the lowest near trees and gardens.
Taking advantage of this natural resistance to the elements, Korean researchers have developed so-called "plant mats," which have shown to lower surface temperatures by at least three degrees and reduce carbon dioxide concentrations in the area by a factor of five.
The special mats are made of a fabric that's been infused with moss and flowering plants known as stonecrops.
"The roots are able to cover an area in a shorter span of time. Therefore, it's a simpler and more mobile process. Compared to existing mats, the roots are also able to take hold much faster."
The plant mats can also be transplanted efficiently to other areas, and give local botanical growers a boost in revenue.
"By utilizing this process in the construction of roofs, for example, research shows that it can reduce the thermal heat within city areas. There have been very high expectations since the results came out.
The research project was carried out by Korea's Rural Development Administration.
They hope that these plant mats can also mitigate heavy rain damage to buildings and eventually play a key role in mainstream urban planning.

韩国研究人员已经开发出一种新的方式来降温城市....而不需要能量削弱空调。 该系统采用全天然植物为基础的地垫，以确保冷却器和环保的城市中心。
金民吉先生向我们展示了这家生态友好的方法是如何工作的。这里炒热在首尔的中心地带，与烈日正午的阳光若隐若现的开销。
固执的热浪继续让闷热的条件下，尤其是在城市地区。
水泥人行道散发出来的热量可以达到39摄氏度，而车辆周围空气温度可上升到惊人的42度。 但大自然知道如何保持冷静，汞读数最低附近的树木和花园。
趁着这自然元素抗性，韩国研究人员已经开发出所谓的植物垫”，这已显示出较低的表面温度至少有三个度和减少二氧化碳的浓度由五个因素在该地区。
特殊垫子的面料，被灌输的苔藓和开花植物称为stonecrops的。
“的根源是能够在更短的时间跨度覆盖面积，因此，这是一个更简单的移动的过程，与现有的垫子相比，根也能够把握快得多的。
植物垫也可以有效地移植到其他地区，并给当地的植物种植者收入的升压。
“通过利用这个屋顶的建设过程中，例如，研究表明，它可以减少城区内的热，已经有非常高的期望，因为结果出来了。
该研究项目由韩国农村振兴厅进行。
他们希望，这些植物垫也可以减轻暴雨对建筑物的破坏，并最终在主流城市规划中发挥了关键作用。
