对应的英语： Dust and sand storms are among nature's most violent and unpredictable phenomena. High winds lift dirt or sand particles into the air, unleashing a turbulent, suffocating cloud that can reduce visibility to almost nothing in a matter of seconds and cause property damage, injuries, and deaths. No matter where you live, it's a good idea to know what to do if you see a wall of sand racing toward you. 1）Put a mask over your nose and mouth. 2) Protect your eyes. Eyeglasses offer minimal protection from blowing dust or sand, but airtight goggles are better. 3) Look for shelter. Even a parked car will do, so long as it is off the road in not in danger of getting hit.
Environment is an important topic that more and more people are concerned about it. It is necessary to protect our environment because it helps keep us from suffering any disasters in the nature. China dust storms is a seasonal meteorological phenomenon which affects much of East Asia sporadically during the springtime months.The air quality will become rather terrible with the sand storm. How to protect our environment? Many scientists have been discussing this topic all over the world. In my opinion, we need to care about wild life and our natural resource. Some people keep hunting wild animals and killing them for food and clothes. At the same time, our human being have been affected by these wild animals' diseases. Businessmen keep their industries develop so that many pollutants have been released to the air and water. The pollution does seriously harm to our normal lives. On the other hand, we need to save our water. I often see people waste a lot of water every day. They don't know that our natural resources are so limited with huge growing population.
As far as I know,river pollution exist so many places in our country.A great deal of dead fish can be found floating on the surface of the river because of the serious pollution.Besides river pollution,there are also air pollution,soil pollution and so on.They have done great harm to human lives.Fortunately,more and more people have come to realize how serious the problem is.The government has begun to take measures to fight against pollution.But there is still a long way to go.We should take care of our earth and try our best to win the buttle against pollutin.
I come from Inner Mongolia.My hometown suffered from sand storm seriously.sand storm is really terrible:when it comes, the sky will probably turn yellow and in contrast all the lightening bars' color turn into blue.Strong wind will follow, all the people will hurry home.If you stand in the wind for 3minutes, your hair will need 3time-wash after the disaster! The cause for it is the over-herding,which make the grass land into desert.sand storm can do great harm to the live stock of the farms,it can spread desert and kill cattle,making the traffic disabled,the invisibility let the planes cancelled.What' more, plants in the farmland will be buried,food supply will lose. There are some way to prevent it from happening: Plant grass and tress according to the topography;set limit to herding;search for International backup.Here is a good news for it.China, Korea,Mongolia and Japan will cooperate to father sand storm On May.29, in the conference " International conference of Women and prevention and fathering work for desertification" held in Beijing, the director for sand storm prevention office of State forestry administration, Liu Tuo said that China, Korea, Mongolia and Japan have constituted the general layout for fathering the sand storm in order to meet the harm by it.
In general, the sandstorm refers to carry large amounts of dust storm, tend to occur in the desert or semi-arid areas. But have strict scientific sense of the sandstorm. Weather in general with visibility to differentiate between the sand and dust storm: visibility less than 1 km to dust storms, visibility 1 km in more for dust or flying sand weather. Experts with the China environmental testing station with the concentration of suspended particles in the air as a measure. Recently suspended particle concentration dust weather in Beijing general not more than 1000 micrograms per cubic metre, and dust concentration is far more than the index. The expert points out, should distinguish between dust, flying sand and dust, etc. Three kinds of common weather conditions. Dust weather, diffuse tiny particles in the atmosphere, dust from outside, the flying sand weather of sand is local. Dust and flying sand dust weather with the two kinds of weather conditions, but the ratio of the two are changed. Dust weather as part of the index, can only be called a sandstorm. Yi般而言，沙尘暴是指携带大量尘沙的风暴，多发Sheng在沙漠或半干旱地区。但科学意义上的沙尘Bao却有严格的指标。气象上一般以能见度来区Fen沙尘与沙尘暴：能见度小于1公里的为沙尘Bao，能见度在1公里以上的为沙尘或扬沙天气。 Zhong国环境检测总站的专家们则以空气中悬浮颗粒物De浓度作为衡量指标。最近北京沙尘天气时悬Fu颗粒物浓度每立方米一般不超过1000微Ke，而沙尘暴时的浓度是要远远超过这个指标的。 Zhuan家指出，应该区分浮尘、扬沙和沙尘等3Zhong常见天气情况。浮尘天气时，大气中弥Man细小颗粒物，灰尘多由外地而来，扬沙天气卷起的Sha土则完全是本地产生的。沙尘天气兼有浮尘和扬沙Liang种天气情况，不过二者所占的比重有变化。沙Chen天气达到一定的指标，才可称作沙尘暴。
Sand-dust storm is a weather event mainly occurred in the arid and semi-arid regions of the world,which is caused by the sand and dust blown into the atmosphere by strong wind.After its occurrence,the atmosphere becomes very dusty and the sight distance in the horizontal direction is less than 1000m.Sand-dust storm is also a natural event that can cause serious disaster and soil erosion.Consequently,sand-dust storm can be a indicator of the degree of desertification. The occurrence of sand-dust storm is mainly controlled by atmosphere circle,weather condition,and characteristics of land cover.However,after its occurrence,human being can do nothing to it.To reduce its occurrence frequency and the possible caused disasters,the only practicable way is to improve the condition of land cover.Therefore,researches focus on the relationship between land cover and sand-dust storm can not only reveal the occurrence mechanism of sand storm but also provide the theoretical basis to control it.Besides,these researches can also provide theoretical basis for the actions to improve the eco-environment in Northwest China.
我国是世界上主要的“气候脆弱区”之Yi，自然灾害频发、分布广、损失大，是世Jie上自然灾害最为严重的国家之一。20Shi纪的观测事实已表明，气候变化引起的Ji端天气气候事件（厄尔尼诺、干旱、洪涝、Lei暴、冰雹、风暴、高温天气和沙尘暴等）出现频率Yu强度明显上升，直接危及我国的国民经济发展。Yin此，我认为，现在应该非常重视防灾减Zai的问题。在防灾减灾中应该坚持“预防为主”De基本原则，把灾害的监测预报预警放到十分突出的Wei置，并高度重视和做好面向全社会，包括社会Ruo势群体的预警信息发布。 气象灾害是可以有较长Yu警时效、较高预测预报准确率的一类突Fa公共事件，加强灾害性天气的短时、临近预报，加Qiang突发气象灾害预警信号制作工作，加强气象预警信Xi发布工作，是提高防灾减灾水平的重要Ke技保障。要依靠科技，提高防灾减灾的综合素Zhi。通过加强防灾减灾领域的科学研究与技Shu开发，采用与推广先进的监测、预测、预警、预防He应急处置技术及设施，并充分发挥专家队伍和专业Ren员的作用，提高应对自然灾害的科技水平。 政府Yu社会团体应组织和宣传灾害知识，培训灾害专业Ren员或志愿者。有关部门通过图书、报刊、Yin像制品和电子出版物、广播、电视、网络等，Guang泛宣传预防、避险、自救、互救、减灾等Chang识，增强公众的忧患意识、社会责任意识和自救、Hu救能力。 通过开展“防灾减灾进社区、Jin校园、进企业、进村庄”行动，使最基层De社区居民、广大中小学生、企业员工、广大农Cun特别是偏远地区的农民、社会弱势群体Zeng强防灾减灾意识，掌握基本的避灾、自救、Hu救技能，达到减灾目的。防灾减灾需要从娃娃Zhua起，把灾害、灾害应急知识纳入中小学教学内Rong。 有关部门应编写自然灾害防御宣传手册与宣传Cai料，广泛宣传与普及灾害知识、应急管Li知识、防灾减灾知识，提高基层群众参与应急管理Neng力与自救能力。 会公众要充分认识灾害预Jing信息的重要作用，了解各类预警信息含义，在收Dao灾害预警信息时，根据不同预警信息、不同的预警Ji别，采取积极有效的应对。需要建立广泛、Chang通的预警信息发布渠道。利用广播、电Hua、手机短信、街区显示屏和互联网等多种形式发布Yu警信息，重要预警信息在电视节目中能即Shi插播和滚动播出。有关部门能确保灾害预警信Xi在有效时间内到达有效用户手中，使他们有机Hui采取有效防御措施，达到减少人员伤亡和财产损Shi的目的。 自然灾害风险指未来若干年内Ke能达到的灾害程度及其发生的可能性。Kai展灾害风险调查、分析https://www.wenku1.net/list/写课改的精彩题目/与评估，了解特定地Qu、不同灾种的发生规律，了解各种自然灾Hai的致灾因子对自然、社会、经济和环境所Zao成的影响，以及影响的短期和长期变化方式，并Zai此基础上采取行动，降低自然灾害风险，减Shao自然灾害对社会经济和人们生命财产所造成De损失。自然灾害的风险评估包括灾情监测与Shi别、确定自然灾害分级和评定标准、建Li灾害信息系统和评估模式、灾害风险评价与对策等。
