What is the purpose of students studying hard all these years, of course

for the better future. Every parent wants their kids have advantage over others,

so they can be outstanding and have a good job. Students learn in campus, they

are in the stage of studying knowledge while getting a job soon, there is

necessary for them knowing something about society.

Before study in college, students focus all their attention on study for

entering a good college, they don’t need to care about other things, it is also

what their parents tell them. After entering college, it is a little different,

at this stage, study is no more the only task, students should have access to

society. They should make some preparation for the job hunting, knowing society

helps them get use to the society quickly. Some students only care about score,

when they find a job, the employer will ask him something about the public news,

but students have no idea, this is so bad. What’s more, getting familiar with

the society makes students find their own positions, they will know what they

want and fight for it.

adjust to finding a job, students should get to know society.

新华字典告诉我,霾就是空气中因悬浮有大量烟、尘等微粒而显得混浊的现象。这种天气对人的呼吸系统损伤严重,特别是户外活动。今天是南京市中小学因霾停课的第二天。早餐后我站在阳台上只见空中灰蒙蒙的,50米远的高楼只看到它的轮廓,再远的就一片模糊,抬头向天空望去,太阳已被灰尘遮住了脸已看不到它的踪迹。一阵汽车喇叭声吸引了我,广场上的汽车都亮着灯,慢吞吞地移动着身体。哎!这样的天气给人们带来多少麻烦。

到了中午天空还没有晴朗,我看见太阳失去了往日的光辉,它被一张巨大的灰网蒙住了脸,那晴朗天空阳光耀眼的威力哪儿去了?是讨厌的霾在作怪。

下午3点多,太阳还没露出它的笑脸,它无法挣脱巨大灰网束缚,只好时隐时现在灰网的后面。3点多的天空跟晴天5点多的天色差不多,该死的霾仍不肯离去。

其实灰霾是人类造成的,人们无节制地把机动车尾气、煤气、焚烧秸秆废气通通排向天空,形成了霾,使我们失去了蓝天。保护地球母亲,大家赶快行动起来吧!

9点了,我们要出门了,我以为雾霾已经消散了,可是我到楼洞口的时候,外面还是白茫茫的一片什么也看不见。妈妈对爸爸说:“今天别开车了,太危险了,不是你开车闯到别人就是别人开车闯到你,我们还是做公交车吧!”我突然觉的很奇怪,就问妈妈:“妈妈,你说雾霾天气不能开车,那我们坐公交车那不和爸爸开车一样吗!”妈妈笑着回答我说:“呵呵,公交车大呀,容易让别的车注意。”

On March 8th, 1975, the United Nation started to celebrate the

International Women’s Day. In China, the women’s day also called “March 8th”day.

Why we celebrate women’s day? There is a long story.

On March 8th, 1909, the Women’s Union of Chicago demonstrated against the

inequality between men and women. They demanded that they should have the same

payments, the same working hours as men had, and they should have the rights to

vote. They even put forward a slogan: Bread and Rose, which stood for equal

payment and a better living standard. This demonstrated had caused international

attention to the women’s rights. A year later, a critical meeting was held in

Demark, in order to promote the women’s liberation and equal rights, the council

members decided to establish the Women’s Day on March 8th. Then March 8th, 1911

just became the first Women’s day.

In our country, during the women’s day, the women usually have a day-off

holiday. The communities or companies will organize the recreational activities

such as a spring outing, a nice dinner and some extra welfare. On this special

day, the women can really realize that a woman’s value is not only giving birth

to a child, doing endless housework, but also find her own status in the modern

society. That is she can make a different. She can do everything that a man can

do. When you look around, you will find that more and more women are acting as

scientists, doctors, lawyers, even leaders. Just try to remember, women rule

half of this world. The life could quite different without their wisdom and

beauty.

Happy International Women’s Day!

篇20:雾霾天气污染引发的思考

全文共 3508 字

+ 加入清单

近年来,全国平均年霾日数呈显著增加的趋势,尤其是以工业发展、城市建设更为迅速的中东部地区更为明显。以下是小编给大家整理的天气污染引发思考的内容,欢迎大家查看。

最近一段时间,最引人关注的当属“雾霾”天气。今年入冬的一场超级雾霾席卷大半个中国。104个城市中毒“沦陷”,平均雾霾天创52年之最;许多城市深陷十面“霾”伏。

金华也在前段时间刚经历了一个灰头土脸的周末,本月6日和7日,市气象台连续发布两个霾橙色预警信号,这在我市尚属首次。7日,金华的PM2.5指数一度高达510,超过500微克/立方米,即“爆表”,该天的平均指数达到了482,列全省第一。

出现如此严重的雾霾天,并不是一个城市的过错,是全国大范围的区域性雾霾天气所致。近年来,全国平均年霾日数呈显著增加的趋势,尤其是以工业发展、城市建设更为迅速的中东部地区更为明显。在受雾霾影响的城市,部分地区能见度不足100米,造成了当地的航班停飞、道路封闭,呼吸系统疾病患者明显增加,给我们的生产生活和身心健康带来了严重的影响和危害。

一、雾霾的概念

雾是由大量悬浮在近地面空气中的微小水滴或冰晶组成的气溶胶系统,是近地面层空气中水汽凝结(或凝华)的产物。霾也称灰霾,霾是悬浮在大气中的大量微小尘粒、烟粒或盐粒的集合体。霾使空气浑浊,水平能见度降低到10km以下。根据中国环境监测总站对重点城市灰霾天气监测结果显示,组成霾的粒子极小,颗粒物PM10尤其是PM2.5是霾的最主要组成部分。PM2.5是指大气中直径小于或等于2.5微米的颗粒物,主要来自工业废气、煤炭燃烧、机动车尾气、扬尘以及挥发性有机物等。雾本身不是污染物,但产生雾的大气环境处于比较稳定的状态,空气中的污染物不易向外扩散,造成集聚效应,在低气压、风小的条件下,低层空气中的水汽与霾相结合,形成雾、霾的混合物。

二、防治雾霾的规划思考

雾霾是工业废气、机动车尾气等过度排放物在特定气象环境条件下的产物。解决雾霾的关键是转变经济发展方式、推行节能减排,使用无污染清洁能源。同时,城市大面积雾霾的产生与城市规划布局存在一定的不合理性有关,是对城市规划的前瞻性、科学性、有效性和城市发展的可持续性的检验。城市雾霾促使我们对传统城市规划进行反思,并对未来规划提出新的要求。

针对金华市在城市规划工作中如何做好雾霾的防治工作,仍需结合自身的地理环境和气候特征,从城市结构、空间形态及城市高层建筑布局上开展有针对性的研究,从而为政府决策、城市规划建设提出合理化建议。

(一)、合理规划城市结构,预留控制城市风道

城市通风廊道也叫城市风道,就是在城市建设生态绿色走廊,在城市局部区域打开一个通风口,让郊区的风吹向主城区,增加城市的空气流动性,把大气污染物吹出去,对城市的雾霾会起到一定的缓解作用,还能改善微气候环境,夏天还可以缓解“热岛效应”。从某种意义上说,“城市通风廊道”更多的是一种对城市结构的改造。

构建大尺度的“城市通风廊道”可从三方面着手:

一是构建绿色廊道。在规划布局上,根据城市主导风向设置通风廊道,从远郊及市区打通城市风道,沿城市快速路、公路、铁路、河流等周边规划一定宽度的带状绿地并严格控制其建设行为,从而形成绿地风廊、道路风廊、河流风廊。如市区开展的城市绿道网建设,三江六岸绿化廊道建设等均很好的构建了城市的通风绿廊。

二是建设被誉为城市“绿色项链”的环城林带。在污染物不变的情况下,如果建设城市通风廊道,就可以增加污染物扩散的速度,而环城林带是全年四季360°的绿色廊道,任何风向吹过可形成城市风道。金华特殊的区域盆地位置,常年平均风速偏小,而随着城市高大建筑物越来越多,阻挡了空气运动和城市风道,严重的影响城市通风散热。金华总体规划对城市三环预留了一定宽度的环城林带,但在城市细化建设时,有些地方并没能完整的按要求控制下来,相反在一环、二环周边高楼林立,像大桶一样对主城区形成包围圈,使主城区污染物不易扩散,导致城市空气污染进一步加重。

三是严格控制城市风口,利用六大绿楔形成城市“穿堂风”。利用山体林地、河谷水道等自然条件,通过串联建设并采用建设限高等规划手段,形成开敞的空间和城市大“出气孔”。目前,金华主城区按照城市总体规划的要求大部分生态通风走廊已基本形成,并正在发挥作用,可确保郊外的凉爽空气吹进来,把主城的热空气置换出去。同时,城市发展对土地的强烈需求,导致六大绿楔逐渐吞噬的现象依然存在,得引起我们高度重视。

三者复合建设将产生叠加效益,其整体的生态效益比起单纯的一项都要强。国内城市如杭州、武汉、上海等均已开展了构建“城市风道”的相关研究和建设,国外如德国慕尼黑、英国伦敦等均在城市规划中考虑到了城市风道的问题。

相关的研究及经验表明,“城市风道”的建设,并不是临时设计做出来的,而是有赖于提前谋划,进行空间预留出来的。它也并不需要大拆大建,可以结合旧城改造、结合新区开发、结合具体项目审批、结合我们的公园建设、生态带来打造,有意识地逐渐完成。

(二)、有效组织城市空间,构建城市风道

在高强度开发的城市中打造城市通风走廊,一方面要构建绿色廊道,另一方面在建设过程中要有意识地考虑气候环境特征,譬如道路走向、建筑布局应考虑城市的主导风向,为风留出一条条的通道。

金华近几年高层建筑量突飞猛进且布局无序,阻挡着风道的形成。金华主导风向为东北风,因此需要东西向道路来组织风道,而且最好能贯穿整个城市,否则风到了某一个地方,被建筑物阻挡,就要再向上“翻越”,延缓了去霾、散热的速度。如江北的锦绣金华,沿回溪公园西侧密麻的布置了一排高层建筑,夏天清凉的东北风原本可以长驱直入,经过义乌江还能夹带一些凉润的江风,顺江堤、公园、道路和比较低矮的建筑群,一路向老城区吹去,但随着回溪街锦绣金华成排成片的高层居住的建设,正好阻挡在风向由东往西吹去的行经路线上,导致风速急剧下降,加剧影响了城西片去霾和散热。

在城市不同功能区中,不同土地价值及开发强度,其高层建筑分布的密度及位置等有所差异,对于一些处于可能影响城市风道的城市功能区内,应当进行城市高层建筑的控制和分析,尤其100米以上高层建筑对城市微气候影响较大。因此,针对城市地理环境及气候特征,在城市重要风道及其周边需开展城市空间高度控制研究,如对三江六岸景观带沿岸进行高层建筑点位设置研究,既未雨绸缪地进行空间预留,同时又可控制并塑造城市天际线。例如:武汉市规划部门2005年曾联合华中科技大学,进行了“城市建筑规划布局与气候关系研究”。该研究即前瞻性的考虑城市开发建设与城市气候之间的相互关系,对从空间形态上解决城市热岛效应和雾霾具有较好的指导作用。

(三)、考虑地块建筑布局与风向的关系,顺应城市通道

“在城市规划建设过程中,有意识地营造出一条‘风走廊’,可以缓解雾霾天气的发生,减少热岛效应的产生。”徐匡迪说。

营造“通风廊道”,即需要控制高层建筑的高度和数量,在高楼林立的地方留出“大缺口”,让城市像人一样拥有“出气口”。预留风道,让风裹挟着污染物顺利出城。

在地块建设层面,目前欠缺在建筑布局中对城市微气候影响的考虑,成片高大建筑立项时,也未进行科学的气象论证,缺少对建筑物高度、朝向是否阻挡了城市风道形成的相关分析,使得城市大气难以良性循环运转,导致城市成为一座透风不佳的城堡,风进不来,霾出不去,成为令人窒息的污染“围城”。

由于金华主导风向为东北风,建筑布局的最佳朝向为南偏西15度左右,若考虑气候对建筑的影响关系,有利城市通风的建筑布局应与城市街道存在一定角度,而在地块建设中,任由高层建筑按其南北向布置,将极易堵塞城市风道。因此,急需开展城市高层建筑布局与城市气候的相关研究,预留不同地块高层建筑空间位置,并研究不同用地性质建筑布局形式对城市风道的影响。如居住小区建筑的布置形式上,错位布局优于行列式;点式和条式结合,优于单一平面布局;面风向半围合式也利于形成良好的通风环境。

下一步,建议围绕城市结构、空间形态及城市高层建筑布局等主要做好以下几方面的工作:

1、学习借鉴其他城市的成功经验,尽快开展城市规划与气候关系研究,从城市规划角度提出改善城市微气候环境的措施和对策;

2、尽快启动城市总体规划的实施评估,对城市发展过程中存在的问题及时进行修正,使城市建设更加科学、合理、有序;

3、开展市区绿地系统专项规划修编和绿线规划的编制工作,明确各类绿线的控制范围,并按城市绿线管理办法严格执行;

4、根据城市绿地系统专项规划,加快市区公园、城市绿楔、环城林带的建设,构建以三江六岸绿带为骨架,城市绿楔为通风口,环城林带为360°通风廊道的生态绿地系统。
