Nearly one-fifth of China's land has bee

desertified due to natural and human factors,forestry chiefs said

yesterday.

A national survey reveals areas now classified as "sandy land" top

1.74 million square kilometers-affecting 18.2 per cent of the

country's total territory at the end of 1999.

This represents a increase of 17,180 square kilometers of sandy

land--which is the transitional state of soil before it prevents

any cultivation--in just five years,the State Forestry

Adiministration(SFA) said.

Distribution covered almost all of China's provinces, with 97 per

cent concentrated in 10 arid or semi-arid provinces and autonomous

regions in the west.

China's deserts witnessed a increase of 52,000 square

kilometers beeen 1995-1999.

Now six national programs have heen launched by the government to

halt the spread of deserts.rehabilitate ecosystems in semi-arid

areas and prevent more dry land from turning into sandy soil or

desert-like areas.

These projects are designed to cover more than 85 per cent of

China's sandy land to form a framework for the country's long-term

strategy of controlling desertification.

The National Afforestation Committee(NAC) yesterday honored

individual and anization for their outstanding efforts in

controlling the spread of sandy land.

Shi Guangyin and 100 other individuals plus 100 units engaged in

afforestation were mended by forestry and personnel authorities

at a ceremony in Beijing,for their decades of work on improving

land quality and preventing desertification.

The event was held in the Great Hall of the People to memorate

the eighth World Day to Combat Desertification and Drought.

Honored as "the National Hero of Controlling Sandy Soil"--the

highest title of its kind in China.Shi,a farmer from

desert-threat-ened Dingbian County in Northwest China's Shanxi

Province, has succeeded in bringing 13,000 hectares of sandy soil

under effective control and turning them into productive soil

through planting trees and grasses.

"What Shi and the others did is a precious treasure of the Chinese

nation," said SFA Director Zhou Shengxian.

"It should be followed by more people to support China's

intensified fight against expanding sandy land and worsening

desertification in the years ahead."

Zhou said the country"has not fundamentally reversed the trend of

deteriorating ecosysterms,with desertification worsening as drought

persists and human activities,like overfarming and

overagazing,increase."

Desertification Desertification is being a serious problem in recent years. A table shows the trend of desertification in a region in o aspects. According to the table, area of 560 square kilometers was deserted in the 1980s. In the 1990s, the area of desertification took a leap to 810 square kilometers. In the following ten years, the number raised more slowly than the first ten years. The area of deserted land finally reached 980 square kilometers. The table also shows the frequency of sandstorms in the region. From 1980s to 1990s, the frequency of sandstorms raised sharply. Because the area of desertification took a turn to rise slowly, the frequency went up to 16, by about 30 percent only. Desertification is obviously an international problem now. It is caused by the decrease of woods and vegetation. The water in the ground is kept by the plants, so the land may turn to desert without enough plants. Desertification can cause bad weather like sandstorms and even change the climate of a region. And it also destroys the variety of plants and animals. So far there has not been an effective way to solve the problem pletely. But there are many things humans can do to prevent the desertification from being more serious. Planting more trees or stopping cutting down woods would work. There is a long way to go

请参照一下表格和2点...

[1、图画/图表描述段]As is shown in the picture, we can see clearly the relation ship beeen people and desert. In the left hand picture, people are fleeing from greedy sand hills because they cut down all the trees. The caption reads, ”As the sand advances, we retreat.” In the right hand picture, the people have returned carrying tools, water, and young trees to plant the land again. The caption reads: “As we advance, the sand retreats. ”[2.意义阐述段]It seems to me that the cartoonist is sending a message about the importance of trees in water and soil conservation and the need for everyone to fight against the danger of the desertification. In fact, what he is saying is that the sand hills will drive away from the land if we do fight against the sand. If we let this situation continue as it is , our environment will suffer a great destruction.[3、.建议措施段]The best way to fight back against the greedy desert in made clear in the second picture. There the local people are actively setting about the task of planting trees to reclaim the land and make it fertile. The fact that there are three people in the picture, each with a different job suggests that working together is the key to success in the battle against soil erosion.

Resulting in about the causes of desertification in China, Ma Wenyuan, researchers believe that, with increasingly frequent dust storms, desertification has drawn increasing attention. The continuous expansion of desertification, in addition to climate change factors, mainly caused by irrational human activities, mainly can be summarized as ＂six excesses＂ - Ken abuse, deforestation, excessive grazing, excessive, indiscriminate exploitation of water resources and hunting, And while many factors are usually additive effect, making China's the growing trend of desertification.

沙尘暴的形成需具备4个条件。

一是地面上的沙尘物质。

它是形成沙尘暴的物质基础。

二是大风。

这是沙尘暴形成的动力基础，也是沙尘暴能够长距离输送的动力保证。

三是不稳定的空气状态。

这是重要的局地热力条件。

沙尘暴多发生于午后傍晚说明了局地热力条件的重要性。

四是干旱的气候环境。

沙尘暴多发生于北方的春季，而且降雨后一段时间内不会发生沙尘暴是很好的证据。

春季沙漠的边缘地区，由于长期干旱，而且地表少有植被覆盖，当有大风来临的时候地表的沙尘很容易被吹起且被输移，但由于沙子粒径较大，不易形成悬移（悬浮移动，是小颗粒物质保证长距离输移的必要条件），因此不能长距离输移，这也是距沙尘较远的地区只有降尘而少见扬沙的主要原因。

如果风持续的时间很长，形成悬移的浮尘能够被输送到很远的地方，所经过的地区就会出现沙尘暴；当风速减弱到一定程度后，浮尘就会降落，该地就会出现降尘天气。

如果此时降水，就会形成所谓的“泥雨”。

从沙尘暴形成过程所需的4个条件看，黄土高原、广袤的沙漠及由人为因素的破坏正处于荒漠化过程中的土地，北方春季末耕种的土地及处于施工过程中的基础设施（如高速公路等）为沙尘暴的发生提供了充分的物质源；而春季北方地区的干旱，又使沙尘暴发生的可能性增强；大风的产生是一种复杂的大气现象，主要是冷锋活动或经纬向环流调整作用的结果。

由此可见沙尘暴的产生是多种复杂因素共同作用结果，人类活动对自然界的破坏导致土地荒漠化的加剧，对沙尘暴发生产生了极其重要的作用，而近几年全球干旱（其原因目前尚未知）等异常天气现象也对沙尘暴的发生起了不可估量的作用。

所以说人类活动对沙尘暴的产生只起到一定作用，并不能说沙尘暴就是人为因素造成的。

The formation of the sandstorm to have the four conditions. One is the dust on the ground material. It is the material basis of form sandstorm. 2 it is winds. This is the power of the formation, is fundamental to the power of the sandstorm long-distance transport of guarantee. Three is not stable air condition. This is an important local thermal conditions. Sandstorm occurs more often in the afternoon that incorporates the evening the importance of thermal condition. Four is the dry weather environment. Born in the north of the sandstorm multiple spring, and rain after a period of time within a won't happen very good evidence is dust storms. The edge of the desert in the spring, due to long drought, and surface vegetation cover, when there is little wind es on the surface of the earth is easy to be blowing dust and sand, but due to lose move large particle size, is formed not easily movable (suspension movement, it is ... all particle material guarantee to lose the necessary conditions of long distance move), and therefore can not move long lost, this is far from the dust in the dust and rare only micrometeorology main reason. If the wind last time is very long, form the dust suspended loads can be transported to a very far place, through which areas will appear sandstorm; When the winds weaken to certain degree, floating dust will the landing, the dust weather will appear. If the precipitation, can form the so-called ＂NiYu＂. The formation process from the four conditions look, the loess plateau and vast desert and by the destruction of the human factors in the process of desertification is in the land of the north, at the end of the spring farming land and in the construction process of infrastructure (such as high speed road, etc.) for the dust storm occurrence providing full source material; And the spring drought in the north, and the likelihood of the sandstorm strengthened; The winds generated is a plex phenomenon, mainly is the cold air activities or to the circulation of the regulatory role longitude results. This shows the generation of sandstorm is DuoZhong plex factors results of human activity on the natural world to disruption of the desertification intensifies, dust storms happen to have an important role, and in recent years the global drought (the cause isn't yet known) abnormal weather phenomenon also to the dust storm occurrence have played an important role. So that human activities for the generation of dust storms only play a role, and can't say dust storms are caused by human factors.

Natural disasters, often caused huge losses. Natural disasters, there have been unscrupulous human deforestation, which led to the natural problems, such as soil erosion, desertification, dust storms, causing extensive damage.Human beings should protect the forest environment, thereby preventing many natural disasters, along with industrial development, in a large number of harmful gas emissions, resulting in decreased air quality, global warming, the atmosphere of vulnerability, and even lead to acid rain. Human beings should protect the natural, can reduce losses. 翻译：【对自然灾害的发生，往往会带来巨大的损失。

自然灾害，不断有肆无忌惮的人类砍伐森林，从而导致了自然的问题，如水土流失，荒漠化，沙尘暴，造成大量破坏。

人类应该保护森林环境，从而防止许多自然灾害，随着工业的发展，在有害气体的大量排放，导致空气质量下降，全球变暖，大气中的漏洞，甚至会导致酸雨。

人类应该保护自然，就可减少损失。

】

中国的青山绿水，正遭受到极度的摧残。

工业废水的大量排放污染了我们民族的血液。

森林大面积地砍伐、毁坏，使得洪水肆意猖獗，所到之处，民不聊生，眼睁睁看着家园被洪水吞噬，无不心痛。

更有甚者，祖国的大动脉——黄河，已经不再是昔日养育中华民族起源的鱼肥水美之处了，却成了世界含沙量最多的河流，每年带走的泥土，不可估量。

大片土地的沙漠化，也正袭击着我们居住的城市。

人们为了贪图自己的利益，在食品里放添加剂来牟取巨大的利润。

由于食物中毒而导致死亡的事也时有发生。

在校园里，同学们为了方便而忽略了环保的意识，口香糖随口一吐，致使校园的地面上留下了一道道黑色的“伤疤”。

这数也数不清的道德问题正困扰着这条“东方的巨龙”甚至影响了它未来的发展。

相比之下，我们的邻国，日本与韩国，在2002年日韩世界杯上，球迷观看完足球比赛后，离开后的座位竟然没有留下一个废物，我依旧记得报纸那天报道的标题是“可怕，可敬的日韩民众”。

而国民在每一次公众场所聚集后，都需要工作人员反复地检查，确定不再有垃圾。

更有甚者，每当表演与比赛不是那么尽如人意时，总是能见到在比赛场地上看台上有着塑料瓶和废纸团等垃圾。

在美国，父母带着小孩子在商场等公共场所是，若有垃圾，不论垃圾箱有多远，父母都会鼓励自己的孩子，自觉地把垃圾扔进垃圾袋。

而中国的父母在孩子手中有垃圾时，则是告诉他将垃圾偷偷地扔在一个角落，根本就没有想到这样会有什么后果。

更夸张的是街头大小便与城市小广告比比皆是。

先不谈中国与其他发达国家的差距到底在哪里，上述的话语也该能让各位心知肚明了吧。

说到我自己，我在以前也确实有过没有注意道德规范的时候，现在，我已经不再是小孩，当口中有痰是，我会稍加思考，拿出纸巾，包好，再扔入垃圾桶。

当手中攥着糖纸时，我也会稍加思考，直到手中冒汗，我也会扔进垃圾桶。

当眼前面对着红灯时，我依旧会多加思索，静静地等待着绿灯的再次闪烁……你要问我为什么，我会告诉你：我是新一代的中国人。

如今，21世纪的中国在发展的列车上畅通无阻地前进时，我们依然不能忘记那“老掉牙”的道德行为，它就像是一把“双刃剑”，既可以成为发展列车上的“润滑油”，也可以成为发展道路上的“拦路虎”。

在新闻中不断报道着经济、财政、农业生产、文化教育的同时，我也希望看到一些关于道德素质的报道。

明天的我们，应该如何行动呢？我呼吁：不要再破坏我们自己的家园了，保护环境人人有责，保护环境从我做起，从现在做起！

在我们日常生活中 ，生活环境是十分重要的.但在日常生活中人们在保护环境上并不十分重视. 比如说我们的周边环境 .在我们区后面的草坪中，开着许多花朵.但在草坪中，却也有人扔垃圾，堆废纸.夏天，有许多蚊蝇在那里飞来飞去，不但影响了小区形象，还污染了环境.对社会，对我们的身体健康都很不利，还破坏了地球. 为了能让我们的环境优美，不受到伤害.有许多老人来打扫大街，绿化草坪.他们每天早出完归，为了祖国的绿化环境不惜一切代价。

但那些不爱护环境的人偏偏还要去破坏，我们一定要为不爱护环境的人做好思想工作，让他们早一日改掉恶习。

在我们上学的路上，也有许队多同学乱丢废弃物。

比如说：有的同学把小吃袋扔在校门口外，还有的同学把叠好的纸飞机随意乱扔，甚至顺着墙扔进学校.他们的这些行为不但一次又一地影响着学校，还给每天早晨做值日的同学带来了很 ... 烦。

在校会上，老师一次又一次叮嘱、说服，但有些同学并不听劝，而是继续破坏环境，缩短地球的寿命。

有一次，学校组织我们2—6年级同学到采俸公园的草坪上捡白色垃圾。

在出发之前，我心里想，平常到采风公园玩的时候，觉得那里比较干净。

今天去捡白色垃圾，应该很少，捡起来一定很轻松吧。

但当我走道那里，低头一看的时候，却把我惊呆了。

地上有许多垃圾。

废纸、烟头、塑料袋等。

这些到处都是，一块绿色的草坪，在游人的破坏下成了一片环境污染地，这是多么严重的环境问题。

面对这块草坪，使我们精神奋发，努力去消除那些垃圾。

经过我们100分钟的劳动，草坪终于恢复到了最初的美丽，名花齐葩争芳斗艳。

Having been deeply influenced by the sandstorm which had attacked the northern part of Shandong Province, I feel it is our duty to plant trees and protect the environment. There were many trees here in the past, but now people destroy the woods to develop more fields for cultivation. Then, the climate changed and the desertification became serious . Therefore, we should all know that it's our responsibility to plant trees.
