1. 海洋污染百分比

全球水資源，咸水占97.5％，淡水占2.5％，在這2.5％中，又有87％是人類難以利用的兩極冰蓋,、冰川、冰雪。人類可以利用的淡水只占總水量的0.26％,，而這些淡水大部分是地下水，實際上,，人類可以從江河湖泊取用的淡水只占總水量的0.014％,。

地球表面、巖石圈內,、大氣層中和生物體內所有各種形態(tài)的水,，包括海洋水、冰川水,、湖泊水,、沼澤水,、河流水、地下水,、土壤水,、大氣水和生物水，在全球形成了一個完整的水系統(tǒng),，這就是水圈,。

2. 海洋污染的數據統(tǒng)計

就目前的開采技術而言，基本上無論是哪種方法,，都是促使可燃冰中天然氣與水的分離,，要促使其分離，必然要改變其溫度及壓力環(huán)境,，這樣就可能會產生一系列不可預知的環(huán)境問題,，如溫室效應的加劇、海洋生態(tài)的變化及引起地質災害的可能,。

可燃冰的成分主要是甲烷,，甲烷是一種強溫室氣體，對大氣輻射平衡的影響僅次于CO2,。

目前探明全球可燃冰儲量的甲烷是大氣圈中甲烷的5000倍,，在開采的過程中，即使如此巨大的甲烷總量哪怕是0.5%進入大氣層,，對全球變暖的影響也是難以估量的,，如果開采中稍有不慎，則必然會加劇溫室效應,。在海洋中開采可燃冰帶來的環(huán)境問題更多,，一方面甲烷如果直接進入海水中，則會很快發(fā)生微生物的氧化反應,，從而會改變海水的化學屬性,，如果大量進入，其氧化過程中會消耗海水中大量的氧氣,，使得海洋缺氧,，這樣勢必會加速海洋生物的死亡；

另一方面大量直接進入海洋的甲烷還可能會加速海洋氣化及海嘯,，導致海水加速流動及氣壓卷吸,，會嚴重危害海面船只及作業(yè)平臺的安全，甚至強對流的海水會直入空中,，影響航空及陸地建筑的安全,。

在開采可燃冰的過程中，會分解大量的水,，這些水會稀釋巖層空間,，使得地層結構穩(wěn)定性變差,，容易引發(fā)地質災害。

在海洋環(huán)境中,，無論是減壓分解還是激熱分解,，都會導致海底陸坡區(qū)的穩(wěn)定性下降，嚴重則會發(fā)生海底坍塌,，如毀壞海底輸電或通信電纜和海洋石油鉆井平臺等設施,。

就目前的開采方法來看，無論是哪種方法都不能單獨實施,，必須是幾種方法的結合,，如果使用二氧化碳置換法、化學試劑減壓法與其他方法的結合實施,，則勢必會產生新的問題,，這些化學試劑及二氧化碳注入到地下后，會嚴重污染地下水源,。

3. 海洋污染具體數據

你指的有點寬泛,，主要指海底地貌：

如同陸地上一樣，海底世界有高山,，有平原,，還有深溝峽谷。這個世界并不象人們所想像的或是象表面看起來那樣平緩和寧靜,，相反卻是地球上最活躍最動蕩不安的地帶,。地震火山活動頻繁，形成高山峻嶺,，只不過一切都掩蓋在海水之下進行而已,。

世界各大洋的洋底形態(tài)雖然各不相同，但基本上都是由大陸架,，大陸坡,，島弧海溝，大洋盆地,，洋中脊（海底山脈）幾個部分組成。

我們平時所看到的海岸線并不是大陸與海洋的分界線,，實際上,，在海面以下，大陸仍以極為緩和的坡度延伸至大約200米深的海底,。這一部分就是大陸架——被海水淹沒的濱海平原,，這里成為海洋生物的樂園，可以發(fā)現許許多多的海洋動植物在此處安居樂業(yè),，繁衍生息,。

大陸架以下,，是大陸架向大洋底過渡的斜坡，坡度陡然增大,，一般為3-4度,，有的甚至超過10度，水深急劇增加,，一般為200-2500米,。這就是比較狹窄的大陸坡，它的底部才是大陸與海洋的真正的分界線,。

超過大陸坡,，就是深邃的海溝或島弧一海溝系。在此處,，大洋板塊俯沖到大陸板塊以下,，交錯地帶形成了“V”形的海溝，是海洋中最深的地方,，與相鄰的島弧構成了地球上最大的高度差,。例如秘魯-智利海溝深8000米，其背靠的安底斯山海拔6500米以上,，它們之間的交差為14500米,，若不是被海水覆蓋，這將是最雄偉壯觀的景象,！

這一帶由于地處兩個板塊的邊緣,，故地震、火山活動頻繁發(fā)生,，跨過海溝再向海洋深處,，就到了廣闊無垠的大洋盆地。其深度在2500-6000米之間,，大部分是深海平原,，面積占海底總面積的77%，遼闊平坦,，但景色無奇,。在平原的周圍，分布著綿亙千里的海嶺,，陡峭的海山峰和光滑如刀削的平頂山,，其中還有深海谷，斷裂帶和海槽等,，海嶺和海山皆因火山組成,，海山甚至可以露出海面成為島嶼，如太平洋的夏威夷群島。

再深入洋底,，就來到了洋中脊,，與一般海嶺不同，他們是海底擴張的中心,。而且洋中脊是一個世界性體系,，橫貫各大洋，從北冰洋開始,，穿過大西洋,，經印度洋，進入太平洋,，逶迤連綿約七萬余公里,，就好像是大洋的脊梁，任何一條陸地山脈都不能與之相媲美,。

各大洋洋中脊的位置均不相同,，大西洋中脊貫穿大洋中部，與兩岸大致平行（中脊各稱由來）,，中軸為中央裂谷分開,，兩側內壁陡峻，兩峰嶙峋,，蔚為奇觀,；印度洋中脊猶如“入”字分布在大洋中部；太平洋中脊位于偏東的位置上,。三大洋中脊在南部相互連接,，而北端卻分別伸進大陸。

這就是海底世界

5. 海洋污染率

海洋污染物依其海洋污染來源、性質和毒性,，可分為以下幾類：

①石油及其產品(見海洋石油污染),。

②金屬和酸、堿,。包括鉻,、錳、鐵,、銅,、鋅、銀,、鎘 ,、銻 、汞 ,、鉛等金屬,，磷、砷等非金屬，以及酸和堿等,。它們直接危害海洋生物的生存和影響其利用價值,。

③農藥。主要由徑流帶入海洋,。對海洋生物有危害,。

④放射性物質。主要來自核爆炸,、核工業(yè)或核艦艇的排污,。

⑤熱污染和固體廢物。主要包括工業(yè)冷卻水和工程殘土,、垃圾及疏浚泥等,。前者入海后能提高局部海區(qū)的水溫，使溶解氧的含量降低 ,，影響生物的新陳代謝,，甚至使生物群落發(fā)生改變;后者可破壞海濱環(huán)境和海洋生物的棲息環(huán)境。

⑥有機廢液和生活污水,。由徑流帶入海洋,。極嚴重的可形成赤潮。

6. 海洋污染程度是多少

海洋污染的危害：漁場外遷,、魚群死亡,、赤潮泛濫、海生資源喪失,。海洋污染會導致海洋生物的體內積累毒素,，如果這些體內帶有毒素的海洋生物被人類誤食到身體內，毒素同樣也伴隨食物進入身體后,，將會危及到人類的身體健康,，嚴重的會威脅到生命。

　　海洋污染通常是指人類改變了海洋原來的狀態(tài),，使海洋生態(tài)系統(tǒng)遭到破壞,。有害物質進入海洋環(huán)境而造成的污染，會損害生物資源,，危害人類健康,，妨礙捕魚和人類在海上的其他活動，損壞海水質量和環(huán)境質量等,。

　　海洋面積遼闊,，儲水量巨大，因而長期以來是地球上最穩(wěn)定的生態(tài)系統(tǒng),。由陸地流入海洋的各種物質被海洋接納,，而海洋本身卻沒有發(fā)生顯著的變化,。然而近幾十年，隨著世界工業(yè)的發(fā)展,，海洋的污染也日趨嚴重,，使局部海域環(huán)境發(fā)生了很大變化，并有繼續(xù)擴展的趨勢,。

　　防止海洋污染的措施主要有：海洋開發(fā)與環(huán)境保護協調發(fā)展，立足于對污染源的治理,；對海洋環(huán)境深入開展科學研究,；健全環(huán)境保護法制，加強監(jiān)測監(jiān)視和管理,；建立海上消除污染的組織,；宣傳教育；加強國際合作,，共同保護海洋環(huán)境,。

7. 海洋污染比例

你好，給你提供幾條概括性的影響危害,，具體的自己發(fā)揮一下,。

1.污染影響：工業(yè)廢水（如海洋石油開發(fā)、煉油廠,、排海工程,、海岸工程、遠洋運輸危險貨等）

2.生態(tài)影響 ：對海洋生態(tài)影響,，影響生物量,、生物多樣性、影響珍稀瀕危海洋生物的

棲息地,、食源地,、遷徙、繁殖）,有可能引發(fā)赤潮,。

總之,，環(huán)境污染后作為地表水和地下水最終受納水體的海洋，因其環(huán)境容量局部海域有限（尤其是海灣或者封閉海域）,，在大量污染物質進入海洋環(huán)境后不能夠很快的進行稀釋凈化,，污染物累積進而出現各種危害效應。

8. 海洋污染指數

Pollution

Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.

I need to describe the problem. Our ship currently dumps all its rubbish into the sea.It's easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.

I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.

We must act now before it is too late!

海洋污染英語作文二：Reduce Sea Pollution

Several problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence. First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales. Second, fishes can't digest them. Finally, some of the rubbish is inherently toxic, they will posion marine life.

We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish. Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.

As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on. We all need to raise awareness of these problems. It now becomes necessary that we must act now, before it is too late!

海洋污染英語作文三：Sea pollution

Between 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.

In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2003, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2006.

Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).

This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.

海洋污染英語作文四：Sea Pollution

Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.

The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.

The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.

海洋污染英語作文五：Polluting the seas

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

海洋污染英語作文六：Sea Pollution

From the overall situation, wastewater emissions growth speed. Is expected in 2000 will reach 666 tons. City life sewage volume will continue to increase, in 2000 reached about 783 tons. The wastewater of low (estimated at 20% ~ 30%),most of untreated wastewater directly or indirectly discharged into the water body, the serious pollution of water resources. China's seven major river systems in nearly half of serious pollution, city section of river water qualitygenerally exceed the standard 86%. The polluted water, more serious is the Huaihe, Haihe, Liaohe, Songhua River, the downstream Yangtze River and the Pearl River Delta industries in developed region.

River city section of riverpollution, heavy on the river, north to south. In 1990, 94 river city section of evaluation, 65 are subject to different degrees of pollution, accounting for 69.1%, the main pollutants ammonia nitrogen, volatile phenol and oxygen consumption of organic matter. According to the survey, 700000000 peopledrinking water the Escherichi a coli exceed the standard, 164000000 people drink organic pollution of water, 35000000 people nitrate drinking water exceed the standard.

Huaihe is one of the most polluted rivers. Huaihe in the evaluation of the 2000kilometers of the river, 78.7% river does not meet the drinking water standard,the 79.7% section does not meet the standard of fishery water, 32% do not meet the standard of irrigation water. According to statistics, the national 3000 heavily polluting enterprises, enterprises of wastewater discharge of industrial pollution,Huaihe River Basin accounts for 160. A sewage units 1.55 182 towns within the basin, industrial wastewater emissions of 1610000000 cubic meters, 700000000 cubic meters of urban living water emissions. Huaihe sewage irrigation farmland,causing serious crop production; in 1989 the occasion of the Spring Festival, the sewage discharge upstream gate opening, the tap water in Huainan, Bengbu twocity is seriously polluted and not drinking, Huaihe basin, the public drinking watercrisis, people Voices of discontent.

Huaihe basin in many areas of cancer incidence rate than the normal area than 10 times to hundreds of times, some villages in 2/3 of hepatomegaly. At the same time, due to the pollution of the estuary, anadromous fish resources has been damaged, the sharp drop in output, part of the in
