城市綠化的初中英語作文
城市綠化是一直以來都在做的事情,綠化好處多,可它究竟多在哪呢?下面是小編為大家精心整理的關於,希望能夠幫助到你們。
城市綠化
On the earth, whether people or animals, no matter how much you if you want to survive, you must absorb a large number of oxygen, emit large amounts of carbon dioxide at the same time. But the earth is originally stored oxygen is limited, and there are not many, so oxygen should run out in N years ago, oxygen and from where to now? That is about to rely on the green plants.
Green plants can be in the sun for photosynthesis, absorb carbon dioxide to produce oxygen. Research shows that: each plants grow a ton, can produce five tons of oxygen. Absorb one ton of carbon dioxide per hectare of forest land every day, 0.735 tons of oxygen; Grass absorbs 0.9 tonnes of carbon dioxide per day per hectare, produce 0.6 tons of oxygen. So do not have oxygen on earth, as long as there is green in the city can also have the fresh air.
Now, to the rising global temperatures are melting glaciers, frequent floods. Especially in large cities, co2 accumulation is more, the temperature is higher, but if more green belts? , according to the determination of summer temperature of asphalt pavement for 49 degrees Celsius, concrete road surface soil as 46 degrees Celsius, the shade under the road surface to 32 degrees Celsius, the shade under the woods to 28 degrees Celsius. Archaism cloud: Lin deep heat. More green belts can reduce the temperature, heat of heatstroke, prevent pavement thermal expansion, damage to the road.
And big cities noise, dust, green belts and can absorb a lot of dust, purify air, reduce noise, to prevent a variety of disease, create a good living environment.
Green benefits more, not just more generally, for their own, in order to the future of the planet, so why not?
綠化好處多,實在是多,這是婦孺皆知的事情,可它究竟多在哪呢?在地球上,無論人或動物,無論你多厲害你要想生存下去就必須吸收大量的氧氣,同時放出大量的二氧化碳。可地球是原本儲存的氧氣是有限的,而且並不多,這樣氧氣早該在N年前就用光了,現在的氧氣又從哪裡來呢?那就要靠綠色植物了。
綠色植物可以在陽光下進行光合作用,吸收二氧化碳,產生氧氣。研究表明:植物每生長一噸,可產生五噸氧。每公頃林地每天的吸收一噸二氧化碳,產生0.735噸氧氣;每公頃草地每天可吸收0.9噸二氧化碳,產生0.6噸氧氣。這樣一來地球上不就有氧氣了,城市中只要有綠化帶也可以有清新的空氣了。
現在全球氣溫都在日漸升高,導致冰川溶化,水旱災害頻繁。尤其在大城市中,二氧化碳積聚較多,氣溫較高,但如果多綠化帶又會如何呢?據測定,酷夏瀝青路面溫度為49攝氏度,混凝土土路面為46攝氏度,林陰下路面為32攝氏度,林陰下綠陰地為28攝氏度。古語亦云:林深不知暑。綠化帶多了便可降低溫度,消暑納涼,防中暑,防止路面受熱膨脹,損壞路面。
而且城市的噪音大,粉塵多,綠化帶又可以吸收大量的粉塵,淨化空氣,減少噪音,預防了多種疾病,創造良好的生活環境。
綠化好處多,還不是一般的多,為了自己,為了地球的未來,何樂而不為呢?

Don't look at the trees small, small, its role can be big! A tree the effect is not very big, but the role of forest composed of hundreds of trees is big!
We know that the forest can prevent many natural disasters "violation" of our home, and now many cities because of a lack of trees, from the "dust". "mud", etc. The harm of natural disasters. Know these later, such a thought in my heart: I'm going to plant trees, because it to greening the city and prevent natural disasters "infringement". But another kind of idea that I dismissed this idea: my little force, what do for you? I returned a thought: flowers and plants can also be green city! Why can't I kind of flowers and plants? Think of this, haven't. I pulled out my morning glory seeds surviving, put it into the pot.
Ah! A flower is small. Small, but it's like trees, one little effect, but the role of many strains are big. Let's call number: "I make contributions to the sen, a wonderful new home." And action, and let our slogan into reality!
別看樹木小,不起眼,它的作用可大著呢!一棵樹雖然作用不是很大,但由千百棵樹組成的森林的作用可就大了!
我們知道森林可以防止許多自然災害“侵犯”我們的家園,而現在許多城市由於缺少樹木,受到了“沙塵暴”.“泥石流” 等自然災害的危害。知道了這些後,我的心裡產生了這樣一種想法:我要去栽種樹木,因為這樣既能綠化城市又能防止自然災害的“侵犯”。但另一種想法使我打消了這種念頭:我人小力小,幫得上什麼忙呢?我又轉念一想:花草也能綠化城市呀!我為什麼就不能種花草呢?想到此,我拿出我一直沒種的.儲存至今的牽牛花種子,把它種到了花盆裡。
啊!一株花雖小.雖少,但它和樹木一樣,一株沒多大作用,但許多株的作用可就大了。讓我們一起喊出口號:“我為創森作貢獻,共建美好新家園。”並行動起來,讓我們的口號變成現實吧!

Do you know what is on March 12? By the way, is the Arbor Day. On this day, there will be many people go to the obligation to plant trees, in order to maintain the ecological balance. Gradually with the environmental protection consciousness, people took to the streets to buy things with a cloth bag, need not disposable chopsticks, eat at work most of them are using bicycle or electric bus, bus can reduce vehicle exhaust emissions. People in order to protect the environment the slogans, such as: "nanning is my home, to protect the environment depends on everybody." "Don't step on me, the grass also hurts" "to protect the environment starts from me, starts from everyone, from small start around you.
Then say: why do you want to protect the environment? Because people don't know to use a lot of cars to protect the environment, too much exhaust damage the ozone layer, the arctic ice will melt, water will cover the whole earth. So, from now on we will protect the environment, save electricity, can 秏 buyers shop to buy a level, or the secondary energy consumption, air conditioning and the snow is not produce ozone. Later, we are going to sit on electric vehicles, sit on a bike, little bus, reduce the harm to the earth.
Protect the environment, starts from me.
你知道3月12日是什麼節嗎?對了,就是植樹節。每到這一天,就有很多人去義務植樹,為的就是保持生態平衡。人們漸漸有了環保意識,上街買東西都用用布袋裝,吃東西不用一次性筷子,上班工作大多數都使用單車或電動車也乘公車,乘公車可減少車尾氣的排放。人們為了保護環境插了標語,比如:“南寧是我家,保護環境靠大家。”“別踩我,小草也會疼”“保護環境從我做起,從每個人做起,從身邊小事做起。
接下來說一說為什麼要保護環境?因為以前人們不懂得保護環境大量使用汽車,造成太多尾氣排放破壞了臭氧層,那麼北極的冰就會融化,水就會淹沒整個地球。所以,從現在開始我們就要保護環境,節約用電,買家店買一級能秏的,或二級能耗,空調加的也是不生產臭氧的雪種。以後,我們要多坐電動車,多坐單車,少坐汽車,減少對地球的危害。
保護環境,從我做起。
