2. 海洋资源的保护与利用
1、海洋平均深度约为3.7公里。从一般深100-200米的大陆棚坡折开始,大陆坡一路降为广阔的深海平原。约有75%的海床深度在3-6公里间,只有约1%的深度更深。最深的水域分布在较窄的海沟中,其中大部分与太平洋岛弧有关,目前已知最深的是马里亚纳海沟的11034米。
2、大海的许多重要特征皆由海水的温度和盐度决定,此外再加上压力,便决定了海水的密度。海水的热量主要来自其表面吸收的太阳能,而表面的水温会随纬度不同而有明显的差异。
3、海水含有各式各样溶解的无机物,有机物,气体和有机物。除了以上溶解成分,它还含有悬浮微粒物质(如浮游生物)。除了水之外,最丰富的无机成分依序为氯化物、钠、硫酸盐、镁、钙、钾和重碳酸盐等。
4、在赤道至南北纬40°或60°之间,形成一低纬度环流,其流向在北半球呈顺时针方向,南半球成逆时针方向。每个环流的西部都是暖流,东部都是属于寒流。
5、在北纬40°或60°以北形成一高纬环流。其环流方向为逆时针方向,环流西部为寒流,东部为暖流。

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!
海洋污染英语作文二: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!
海洋污染英语作文三: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.
海洋污染英语作文四: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.
海洋污染英语作文五: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.

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
5. 海洋资源环境保护
海洋环境保护规划是海洋环境保护工作的基础和行动方案,制定海洋环境保护规划有利利于海洋环境保护工作有计划、有目的地进行。
海洋环境保护规划主要包括:海洋环境保护目标、具体目标方案、海洋环境保护的主要任务、对各部门和沿海各地区的要求、海洋环境保护主要措施等内容。海洋环境保护规划的确立,是以海洋功能区划为基础的,即根据不同海域的功能来确定海洋环境保护的整体规划。重点海城区域性海洋环境保护规划,是国家海洋环境保护规划的组成部分,根据重点海域区域性海洋环境的特殊性,制定一些特殊的、专门的内容,但其内容的确立,也必须以海洋功能区划为基础。6. 海洋资源的现状 如何保护海洋资源
据资料表明,海上污染的80%来自陆地,陆源污染物向海洋转移,是造成海洋污染的主要根源。
除此之外,来自大气层中的烟尘和一些化学物质也源源不断地归入海洋,某些国家沉放在深水区的放射性物质也有增无减等等。
如今的海洋再也承受不了日益加重的污染负担,人类不能等到海洋的蓝色消失后,再来控制污染、整治海洋。
当务之急是制定并实施保护海洋环境的具体措施。海洋环境保护是在调查研究的基础上,针对海洋环境方面存在的问题,依据海洋生态平衡的要求制定有关法规,并运用科学的方法和手段来调整海洋开发和环境生态间的关系,以达到海洋资源持续利用的目的。
总之,人类应该从失误中尽快觉悟,按自然规律办事,不断提高科学文化素养,树立科学发展观,健全必要的管理法规,依法治理,还海洋一个清洁的水体,让海洋造福人类。我们应该牢记:污染海洋,就是危害人类自己!保护海洋,就是拯救人类自己!
7. 海洋保护对解决资源短缺的意义
因为海洋主权和权益,是国家的根本利益所在,关系到国家和民族的兴衰存亡。保卫辽阔的蓝色国土,是党和人民赋予人民海军的神圣使命。
释义:
海洋既是人类生存的基本空间,也是国际政治斗争的重要舞台,而海洋政治斗争的中心,是海洋权益。全球愈演愈烈的海权之争,背后都是巨大的海洋利益。海洋维系着中华民族崛起的诸多重大安全和发展利益。这些利益主要包括:保卫国家主权与领土完整,防御敌对国家从海上的打击和入侵;保卫支撑我国经济可持续发展海洋资源的安全,维护海洋权益;维护我对外贸易海上航运通道、石油航线以及重大海外利益的安全。此外,还有打击海上恐怖主义、海盗、走私和跨国犯罪等问题,营造和平、良好的地区海上安全秩序;改善海洋环境,维护我国可持续发展和生存空间的质量;等等。历史的经验告诉我们,海洋意识淡薄的国家对海洋权益缺乏敏感性,也不可能有前瞻性和预见性。无法在别人没有意识到的情况下就把事情想好办妥,尤其是按照国际海洋法游戏规则打擦边球,为子孙后代多争取海洋权益。另外,由于意识淡薄,也不可能为维护国家海洋权益产生强烈的激情和冲动,即使有,争夺海洋权益的力度和强度都不足以达到理想的境界。没有系统正确理论的指导,就不可能认识到制定国家海洋战略和海洋政策的重要性,没有战略和政策支撑的海洋事业发展往往会迷失方向。海洋管理体制久议不决,海洋管理机构改革方案难以出台,摇摆不定,主要原因就是缺乏现代意义上海洋管理理论的支撑。国家海洋管理如果走一步看一步,就会落后、矛盾、低效。总之 海洋对一个国家的各个方面都有着非常巨大、不可形容的重要性!
8. 海洋资源保护的意义和重要性是什么
海洋和我们是一个整体,首先,海洋本身对污染物有着巨大的搬运、稀释、扩散、氧化、还原和降解等净化能力。
但这种能力并不是无限的,当局部海域接受的有毒有害物质超过它本身的自净能力时,就会造成该海域的污染。
另外海洋虽然蕴藏许多资源,但海洋资源的再生也是需要时间的,如果我们无节制地开发海洋资源而不注意保护,那么这些资源总有被用光的一天。
所以保护海洋极其重要也十分必要。
9. 海洋资源的作用
海洋是生物进化的发源地!地球上第一种生物体——单细胞生物就是在海洋中最早出现的!譬如:我们现在初中课本上学的草履虫!然后就出现了腔肠动物!也是在海洋中!...之后就出现了脊椎动物——鱼。再后来经过地壳变迁,气候变化的变化,自然条件的影响下鱼类慢慢“爬”上陆地...(有科学家认为鸟类也是生物进化过程中的一环,而且还很重要不过我不了解不好意思!呵呵!)...出现了哺乳动物——灵长类(猴子猩猩等)之后就众所周知了猴子便成了我们大家!
人们常说海洋是生命的摇篮。生命起源于海洋,地球上最早的生命就是细菌、蓝藻、一些单细胞组织,逐渐从海洋向陆地发展,又从猿到人,因此海洋和人类的生存发展是密切相关的。
地球71%的面积是海洋。海洋能够吸收太阳能,太阳能的4/5被海洋吸收以后,再慢慢地向外发散能量。所以人类的热能、清洁空气来自于海洋。同样在海洋里有很多生物,海洋就是通过海洋中的植物吸收太阳能,同时进行光合作用,结果就产生了人类生命所需要的氧气。地球上的氧气大约70%,也就是每年360亿吨的氧气是从海洋产生的。除了产生氧气以外,它还吸收大量的二氧化碳,吸收的二氧化碳是大气的60倍。
