篇10:植树节活动倡议书
全文共 2057 字
+ 加入清单敬爱的老师们,亲爱的同学们:
大家晚上好!春回大地,万象更新。 又是一年芳草绿。在这春意盎然,生机勃勃的阳春三月,我们又迎来了一年一度的植树节。
回顾去年的植树节,大家在活动中积极主动,热情参与,体现出了当代中学生的精神风貌,也展示出我校学生敢于担当、勇于奉献的风采。去年,我们同学老师亲手种下的班级树如今更是绿意盎然、生机勃发。我们大家在班级树下的誓言和高歌还回响在我们的耳畔,我们曾经许下的心愿还记忆犹新,我们的梦想还在,有班级树,逐梦路上我们并不孤单。有少许枯萎的班级树,如果天气允许,去年与我们签合同的单位,会负责在今年的3月12日全部更换,保证我们班级树百分之百的存活率。到时欢迎大家回访我们的班级树,给树浇浇水、除除草、松松土等等。光阴似箭,美好的中学时光转眼即逝。在这美好的时光里,但在这美丽的校园内,我留下了我们的成长印记。
今年植树节也即将来临,这是一个营造绿色环境,期待绿水青山,呼唤人们爱护环境的特别日子。
1979年,在邓主席的提议下,第五届全国人大常委会第六次会议决定每年3月12日为我国的3.12植树节。
1981年12月13日,五届全国人大四次会议讨论通过了《关于开展全民义务植树运动的决议》。这是建国以来国家最高权力机关对绿化祖国作出的第一个重大决议。从此,全民义务植树运动作为一项法律开始在全国实施。
那么大家知道植树对人类到底有什么好处吗?
首先,植树造林可使水土得到保持,哪里植被覆盖率低,哪里每逢雨季就会有大量泥沙流入河里,把田地毁坏,把河床填高,把入海口淤塞,危害极大。要抑制水土流失,就必须植树造林,因为树木有像树冠那样庞大的根系,能像巨手一般牢牢抓住土壤。而被抓住的土壤的水分,又被树根不断地吸收蓄存。据统计,一亩树林比无林地区多蓄水20吨。
其次,植树造林能防风固沙。风沙所到之处,田园会被埋葬,城市会变成废墟。要抵御风沙的袭击,必须造防护林,以减弱风的力量。风一旦遇上防护林,速度要减弱70% ~80%。如果相隔一定的距离,并行排列许多林带,再种上草,这样风能刮起的沙砾也就减少了。
再次,植树造林能为人类提供许多有用的东西。不少水果、药材都是林产品,茶叶、橡胶、新碳等更来自林木。
此外,植树造林能清除完全污染。据统计,一亩树林一年可以吸收灰尘2万—6万千克,每天能吸收67千克二氧化碳,释放出48千克氧气;一个月可以吸收有毒气体二氧化硫4千克,一亩松柏林两昼夜能分泌2千克杀菌素,可杀死肺结核、伤寒、白喉、痢疾等病菌。
植树造林还能减少噪音,美化环境,保持生态平衡,为人类提供理想的学习、工作、娱乐和生活的场所。
绿色是大自然的颜色,绿色孕育着生命与希望,没有绿色,就没有我们人类。
在3.12植树节到来之际,人们纷纷走向田野山岗,履行公民的植树义务。许多人用种植纪念树、营造纪念林、公益林的形式,既绿化环境、减少污染,又铭志于树,寄情于林。
为此,我们学校也为今年的植树节进行了精心的准备,花大力气在得英大道上增添绿意。同学们也应该看到了,有许多工人在得英大道上忙碌做施工挖坑等一系列前期准备工作,植树节的系列活动,我们期待您的参与。
亲爱的老师们、同学们,你们可曾知道,我们曾经布满绿树、风光秀丽、滋养五千年古老文明的中华大地,已被城市高楼、荒漠化土地占去1/3以上。在这大地吐露芬芳的季节,我们在此呼吁:十年树木,百年树人,环保未来,在于我们!
那么,同学们,让我们闭上眼睛一同想象;
如果,每个清晨,我们能听见鸟鸣婉转;
如果,每个夜晚,我们能看到繁星满天;
如果,校园中每片绿叶能染亮我们混沌的双眼;
如果„„有如此多的如果,如果我们可以置身在这么多的如果当中,我们的感受又会如何呢?一身的疲倦不见了,活力又会注满身体。满腹的烦恼抛开了,快乐轻松回到心中„„只有在如此干净舒适的环境中,我们才可以提高效率,更好的学习。
亲爱的同学们、老师们,让我们伸出手来爱护这片净土吧!爱小家爱大家,让我们一齐动手用热情植下一片绿树,用爱心呵护一片绿地。保护地球,热爱祖国,爱护环境,绿化校园,从我做起,从身边做起。为此,在全民义务植树34周年即将来临之际,让我们迅速行动起来,积极参加义务植树活动,使家园的山更青、地更绿、天更蓝、水更清!我们向全校师生发出以下倡议:
1、不破坏绿化,这包括:不采摘花朵,不践踏绿化、不穿越开放式草坪,不到花坛等绿地玩耍,做游戏时远离花木。
2、养成良好的环保习惯,如随手关好水龙头、降低屏幕亮度、垃圾分类处理等小习惯将会成就“蓝色星球”的一片绿。
3、参加社区、学校的护绿活动,为学校、社区的绿化地做保洁工作,看到不文明的行为及时劝阻。
4、请老师们、同学们积极参加“植树节”募捐活动。近期我们将开展自愿募捐活动,募集的全部资金将用于得英大道的树木种植,资金不足部分将由政教处向学校申请补足。并邀请老师们、同学们亲自参与得英大道的植树实践体验活动,从而让师生们在活动中体验成功的喜悦,增强环保意识,生态意识,最后与绿树合影留念。
谢谢大家!

+ 加入清单阳春三月,草长莺飞,一年一度的植树节到来了。为了提高学生爱护花木,珍惜绿色的责任心,3月12日下午,实验小学的学生们在青园社区校外辅导站的协助下开展了以“共创一片蓝天,同爱一份绿色”为主题的植树节活动。
活动中同学们三、四人一组,有挖坑的,有扶着树苗的,有填土的,还有提着水桶来回浇水的,打支撑的,干得热火朝天。他们中有不少人都是第一次参加植树,动作稍显笨拙,但这丝毫都不影响他们对植树节劳动的积极与热情。
活动现场,曹校长、马校长、刘主任、夏主任四处查看,手把手地指导,并提示孩子们注意安全,学生们通过一个半小时的努力,最终顺利完成了栽种工作。轻柔的春风中,看着自己亲手种植下的一棵棵小树,畅想着数年以后它们慢慢长大,枝繁叶茂。
通过本次活动使同学们主动参与到绿化环境中来,懂得关心、爱护绿化,关注、保护生活环境。一片爱心,一份力量对地球而言微不足道,可是实验小学的学生们相信:只要人人都献出一点爱,一份力,“共创一片蓝天,同爱一份绿色”将不再仅仅是口号!

第二天中午,我一吃完午饭,就来到了学生会集合的地方,学生会成员陆陆续续地到来了。人来齐后,学生会主席左手拿着一大袋的抹布,右手拿着两个盛满水的水桶,他一看人都到齐了,就开始分配起了任务。终于到我了,我被分到了擦过街天桥的那一组。之后,我们每个人都拿了一块抹布,各自和各自的组开始了活动。
刚一到天桥,我打算从天桥的上面往下来擦扶手,于是我扶着扶手走了上去。上去后,我看看了自己的手,我的手变得又黑又脏,就好像一大块煤球一样。之后,我拿起了一块抹布,从上往下擦了起来。刚擦了一会儿,我的抹布就变得脏了起来,这时我想:抹布这么脏,擦出来的天桥也不会干净。于是,我走到了水桶前,打算把抹布洗干净。可是我的手刚一接触到水面顿时感到这仿佛不是一桶水,而是一个个尖针插入我的皮肉。我强忍着那一阵阵刺骨的冷,洗了起来。渐渐的桶里的水从清可见底变得十分浑浊,抹布上的泥土也洗干净了,我拿出了抹布,我的手也被冻得没了知觉。接着,我刚要继续开始擦扶手时,那一股刺骨的寒冷又覆盖了我的双手。我强忍着寒冷,向后看了看已经被我擦得光亮的扶手,再看看下面那些落满灰尘的扶手,咬了咬牙,擦了下去。擦着擦着,我渐渐感觉不到了刺骨的寒冷,于是我就这样擦了下去。
终于那原本落满灰尘的扶手变得光亮起来也干净了许多。它反射着阳光,映出了每个人笑脸。这时,我看了看由白色变黑色的抹布,看了看已经冻得通红的双手,这时我感觉不到那阵阵刺骨的寒冷了而是一股暖流从我心中涌了出来。

篇16:植树节英语作文:植树节
全文共 2628 字
+ 加入清单The first Arbor Day took place on April 10, 1872 in Nebraska. It was the brainchild of Julius Sterling Morton (1832-1902), a Nebraska journalist and politician originally from Michigan. Throughout his long and productive career, Morton worked to improve agricultural techniques in his adopted state and throughout the United States when he served as President Grover Clevelands Secretary of Agriculture. But his most important legacy is Arbor Day.
Morton (photo, right) felt that Nebraskas landscape and economy would benefit from the wide-scale planting of trees. He set an example himself planting orchards, shade trees and wind breaks on his own farm and he urged his neighbours to follow suit. Mortons real opportunity, though, arrived when he became a member of Nebraskas state board of agriculture. He proposed that a special day be set aside dedicated to tree planting and increasing awareness of the importance of trees. Nebraskas first Arbor Day was an amazing success. More than one million trees were planted. A second Arbor Day took place in 1884 and the young state made it an annual legal holiday in 1885, using April 22nd to coincide with Mortons birthday.
In the years following that first Arbor Day, Mortons idea spread beyond Nebraska with Kansas, Tennessee, Minnesota and Ohio all proclaiming their own Arbor Days. Today all 50 states celebrate Arbor Day although the dates may vary in keeping with the local climate. (State Arbor Days) At the federal level, in 1970, President Richard Nixon proclaimed the last Friday in April as National Arbor Day. Arbor Day is also now celebrated in other countries including Australia. Variations are celebrated as Greening Week of Japan, The New Years Days of Trees in Israel, The Tree-loving Week of Korea, The Reforestation Week of Yugoslavia, The Students Afforestation Day of Iceland and The National Festival of Tree Planting in India. Julius Sterling Morton would be proud. Sometimes one good idea can make a real difference.
For the homeowner, Arbor Day is an excellent opportunity to take stock of the trees on your property and plan for the future. Inspect your trees. Note any broken branches or evidence of disease or insect infestation. Think about how planting new trees might improve the look of your property or provide wind or heat protection. Take a trip to your local nursery to see whats available and to get new ideas. Walk around your neighbourhood. Are there any public areas where tree planting or tree maintenance might make a real difference to your community? Talk with your neighbours. Find out what their opinions are. And, oh yes, plant a tree.

篇20:植树节活动的目的与意义
全文共 911 字
+ 加入清单每年个个单位都会举办一下有关植树节的活动!那么,举办这些活动对于现在的我们,有些什么目的和现实的意义呢?小编在这里为大家解答一下!
植树节活动的目的是通过这种活动,激发人们爱林、造林的感情,提高人们对森林功用的认识,促进国土绿化,达到爱林护林和扩大森林资源、改善生态环境的目的。是为了动员全民植树而规定的节日活动!
植树节活动也有着相当现实的意义,植树节活动的意义不是在于每个人都要在植树节这天去种一棵树,而是通过植树节的又一次来临,使我们大家更加的关注绿化、环保的问题,更好的去行动起来。
其一,森林能够平衡地球的二氧化碳。森林是二氧化碳的主要消耗者,每公顷森林生产10吨干物质会吸收16吨二氧化碳,释放12吨氧气,这使得森林成为一座巨大的氧气库。因此植树造林已成为减缓温室效应的主要途径。
其二,森林能防风固沙。森林可以通过降低风速、改变风向减少风蚀的强度;林木,尤其是灌木树的强大根系,可以固着土壤颗粒。实践证明,通过营造防风沙林,配合农业、水利措施,会取得良好的防风固沙效果。
其三,森林能够保持水土。森林能够调节径流量和枯水期的水量,还能保持水土,降低河水泥沙含量,减轻洪涝灾害等。观测表明,1厘米厚的落叶层能把地表径流减低到裸地的1/4,泥沙量减少94%。降雨导致裸地土壤的流失量是林地的100多倍,而乔、灌、草结合的固土能力却是纯草的1000多倍。有计算表明,我国森林每年减少土壤侵蚀总量为246亿立方米,减少土壤有机质流失量3.84亿吨,保护土壤的价值达2600多亿元。另外,森林对防止河床升高、水旱灾害等方面,也有根本性的减缓作用。
其四,森林能够涵养水源。森林是天然的“绿色水库”,能促进天上水、地表水和地下水的正常循环。落雨时,有20%以上的雨量被树冠和枝叶截留,5%~10%被地面落叶和杂草截留并吸收,森林内团粒结构的土壤能较快地将地表水转化为地下水。据不完全测算,我国森林年水源涵养量为3473亿吨,相当于现在水库总量的75%,每年水源涵养价值达2500多亿元。
其五,森林能够保护生物的多样性。森林是“物种之家”,是生物多样性和生物基因资源的最大储存库。世界上物种的50%以上在各类森林主要是天然林中栖息 。
