全球性气候变暖已引起世界各国的关注。气候变暖的原因,包括太阳活动,火山爆发,森林大火,地球排气增温和人类活动使大气增温。分析了植树造林有助于缓解气候变暖的原理,包括扩大绿色覆盖面积,增加木材蓄积量,将二氧化碳贮存于木材之中;增加绿色覆盖面积,可以降低城市气温,减少电冰箱、空调开启次数和运行时间,减少电能向热能转化;降低太阳光、热对地气的抽吸作用。
Global warming has drawn the attention of all countries in the world. The causes of climate warming include solar activity, volcanic eruptions, forest fires, warming of the earth’s exhaust and human activities warming the atmosphere. Analyzes the principle that afforestation helps to alleviate the climate warming, including expanding the green coverage, increasing the volume of timber and storing carbon dioxide in the wood. Increasing the green coverage can reduce the urban temperature and reduce the opening times of refrigerators and air conditioners And running time, reducing the energy to heat conversion; reduce sunlight, heat on the ground gas suction.
