描寫城市綠化英語作文帶翻譯
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.
綠化，乃植樹種草也。種植這些含有葉綠素的植物，對改善空氣質(zhì)量有很大的幫助。
首先，綠色植物可以在陽光下進行光合作用，吸收二氧化碳，釋放氧氣。研究表明，植物每生長1噸，可以產(chǎn)生5噸氧。每公頃樹林每天可以吸收1噸二氧化碳，產(chǎn)生0.735噸氧氣;每公頃草地每天能吸收0.9噸二氧化碳，產(chǎn)生0.6噸氧氣。充足而潔凈的氧氣能讓人類身心保持健康。
其次，地球上的樹林每天可向大氣中散發(fā)1.7億噸萜烯物質(zhì)，這種芳香物質(zhì)具有無可比擬的殺菌能力和興奮作用。
然后，綠色植物對空氣中的灰塵、粉塵有良好的過濾和吸收作用，并能阻擋工作粉塵向空氣彌散。據(jù)測定，大氣通過林帶，可使粉塵量減少32%-52%，飄塵量減少30%。
你知道嗎?森林中的負氧離子可達到10-100萬個。負氧離子能調(diào)節(jié)神經(jīng)系統(tǒng)的興奮和抑制狀態(tài)，改善大腦皮層的功能。醫(yī)學專家模擬森林的神奇作用，把負氧離子引進病房。結(jié)果發(fā)現(xiàn)，當環(huán)境中負氧離子與正氧離子的比例控制在9：1時，對氣喘、燒傷、潰瘍、外傷病人的治療可起促進作用
除此之外，綠化還有吸收噪音、減少水土流失等功能。把你的一份力量投入到我國的綠化事業(yè)中去吧，那一抹綠意會向你慢慢訴說它的好處。
