城市绿化
学习啦在线学习网 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.
学习啦在线学习网 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.

Green benefits more, not just more generally, for their own, in order to the future of the planet, so why not?
学习啦在线学习网 绿化好处多,实在是多,这是妇孺皆知的事情,可它究竟多在哪呢?在地球上,无论人或动物,无论你多厉害你要想生存下去就必须吸收大量的氧气,同时放出大量的二氧化碳。可地球是原本储存的氧气是有限的,而且并不多,这样氧气早该在N年前就用光了,现在的氧气又从哪里来呢?那就要靠绿色植物了。
绿色植物可以在阳光下进行光合作用,吸收二氧化碳,产生氧气。研究表明:植物每生长一吨,可产生五吨氧。每公顷林地每天的吸收一吨二氧化碳,产生0.735吨氧气;每公顷草地每天可吸收0.9吨二氧化碳,产生0.6吨氧气。这样一来地球上不就有氧气了,城市中只要有绿化带也可以有清新的空气了。
现在全球气温都在日渐升高,导致冰川溶化,水旱灾害频繁。尤其在大城市中,二氧化碳积聚较多,气温较高,但如果多绿化带又会如何呢?据测定,酷夏沥青路面温度为49摄氏度,混凝土土路面为46摄氏度,林阴下路面为32摄氏度,林阴下绿阴地为28摄氏度。古语亦云:林深不知暑。绿化带多了便可降低温度,消暑纳凉,防中暑,防止路面受热膨胀,损坏路面。
而且城市的噪音大,粉尘多,绿化带又可以吸收大量的粉尘,净化空气,减少噪音,预防了多种疾病,创造良好的生活环境。
绿化好处多,还不是一般的多,为了自己,为了地球的未来,何乐而不为呢?

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!
