描写城市绿化英语作文带翻译
Green, tree and grass planting. Growing these plants containing chlorophyll, is of great help to improve air quality.
First of all, the green plants can be in the sun for photosynthesis, absorb carbon dioxide and release oxygen. Studies show that plant growth and each 1 ton, can produce 5 tons of oxygen. Per hectare woods can absorb one ton of carbon dioxide every day, 0.735 tons of oxygen; The grass can absorb every day 0.9 tonnes of carbon dioxide per hectare, produce 0.6 tons of oxygen. Adequate and clean oxygen can keep human body and mind health.
Second, trees on earth every day can send out 170 million tons of terpenes substances into the atmosphere, the aromatic substance has incomparable sterilization ability and excitation.
Then, the green is good for the dust in the air, dust filtration and absorption, and dust into the air dispersion can stop work. According to the determination, the atmosphere through the forest, can reduce dust amount 32% - 32%, fly ash quantity reduced by 30%.
Do you know? The negative oxygen ion in forest can reach 10-1 million. Negative oxygen ion can adjust the excitement and inhibition of the nervous system, improve the function of the cerebral cortex. Medical experts to simulate forest magic effect, negative oxygen ion into ward. The results found that when the environment is negative oxygen ions and the proportion of oxygen ions control at 9:1, for asthma, burns, ulcers, the treatment of trauma patients can promote role
In addition, greening and absorb the noise, reduce water loss and soil erosion, etc. Your a power to go into our country's green enterprise, the green idea slowly tell it to you will reap the benefits.
绿化，乃植树种草也。种植这些含有叶绿素的植物，对改善空气质量有很大的帮助。
首先，绿色植物可以在阳光下进行光合作用，吸收二氧化碳，释放氧气。研究表明，植物每生长1吨，可以产生5吨氧。每公顷树林每天可以吸收1吨二氧化碳，产生0.735吨氧气;每公顷草地每天能吸收0.9吨二氧化碳，产生0.6吨氧气。充足而洁净的氧气能让人类身心保持健康。
其次，地球上的树林每天可向大气中散发1.7亿吨萜烯物质，这种芳香物质具有无可比拟的杀菌能力和兴奋作用。
然后，绿色植物对空气中的灰尘、粉尘有良好的过滤和吸收作用，并能阻挡工作粉尘向空气弥散。据测定，大气通过林带，可使粉尘量减少32%-52%，飘尘量减少30%。
你知道吗?森林中的负氧离子可达到10-100万个。负氧离子能调节神经系统的兴奋和抑制状态，改善大脑皮层的功能。医学专家模拟森林的神奇作用，把负氧离子引进病房。结果发现，当环境中负氧离子与正氧离子的比例控制在9：1时，对气喘、烧伤、溃疡、外伤病人的治疗可起促进作用
除此之外，绿化还有吸收噪音、减少水土流失等功能。把你的一份力量投入到我国的绿化事业中去吧，那一抹绿意会向你慢慢诉说它的好处。
