1. 海洋与生态环境

就业面特别广的。就业前景还是不错的,毕业生将可在海洋生物行业、环保等单位或部门从事海洋生物资源与环境监测、调查、评价、增殖放流、受损海洋生态系统修复或重建,以及相关领域的教学、科研、经营和管理方面工作,以及解决海洋资源可持续利用和海洋生态环境保护中的实际问题的能力的。

2. 海洋生态环境恶化

渤海的扩大主要是由于河流冲积物和海平面上升导致的海岸线后退、海湾面积扩大。具体原因如下:

1. 河流冲积物的堆积。渤海周边的黄河、辽河等大河源头经过数百年的泥沙淤积,形成了大量的冲积平原和三角洲,这些沉积物随着河流的冲刷不断向海拓展,导致了海岸线后退、海湾面积扩大。

2. 海平面上升。近年来,全球气候变化引起的海平面上升现象也对渤海的扩大产生了一定的影响。随着全球温度的升高和冰川融化,大量的冰川水涌入海洋中,导致海平面上升,从而使得海湾面积扩大。

3. 人类活动。人类活动也对渤海的扩大产生了一定的影响。比如,沿海地区的城市化、工业化、农业生产等活动导致了大量的废水、污水和化学物质的排放,这些物质的直接或间接作用可能导致海洋生态环境的恶化,从而影响海湾的面积扩大。

总之,渤海的扩大是由多种因素共同作用的结果,需要综合考虑各种因素才能全面地解释这一现象。

3. 海洋与生态环境的关系

"尔雅海洋"是指由中国海洋馆所筹建兴建的一个中国海洋博物馆,坐落于中国山东省青岛市。"尔雅海洋"是中国规模最大、科普性最强的海洋博物馆之一,其主要展区包括中华园、世界鱼类馆、水母馆、珊瑚世界、海洋剧场、中国鲸豚馆等。

人类文明是指人类在历史和现代积极探索和创造,不断发展的过程。人类文明涵盖了众多领域,包括语言、文字、文学、艺术、科学、技术、政治、经济、社会、哲学、宗教等。人类文明的起源可以追溯到几十万年前的旧石器时代,发展到目前的现代文明,经历了狩猎采集、农业、手工业、工业和信息技术等多个阶段。人类文明的发展是由人类社会的共同奋斗、进步和创新所推动的,其历程充满了创新、变革和进步。

"尔雅海洋"和人类文明之间没有直接的联系,但在中国山东省青岛市这个城市中,如同中国各个城市一样,人类文明得以繁荣和发展,它所形成的独特的生产力和文化,促成了中国海洋馆创立的"尔雅海洋",两者之间共同构成了青岛城市文化生态,不断地为中国和人类文明增添新的活力和能量。

4. 海洋与生态环境专业

题主你好,海和洋不完全是一回事,它们彼此之间是不相同的。

洋,是海洋的中心部分,是海洋的主体。世界大洋的总面积,约占海洋面积的89%。大洋的水深,一般在3000米以上,最深处可达1万多米。大洋离陆地遥远,不受陆地的影响。它的水温和盐度的变化不大。每个大洋都有自己独特的洋流和潮汐系统。大洋的水色蔚蓝,透明度很大,水中的杂质很少。世界共有4个,即太平洋、印度洋、大西洋、北冰洋。

海,在洋的边缘,是大洋的附属部分。海的面积约占海洋的11%,海的水深比较浅,平均深度从几米到二三千米。海临近大陆,受大陆、河流、气候和季节的影响,海水的温度、盐度、颜色和透明度,都受陆地影响,有明显的变化。

海洋生态价值是区别于劳动价值的价值系统,大致包括海洋资源价值和海洋生态环境价值两个既有联系又有区别的方面。其联系表现为很多直接构成海洋经济要素的海洋资源必须同时具备一定的海洋生态环境质量;区别在于海洋生态环境价值具有空间不可移性和整体作用性以及一定地域的消费者共享性等质的规定性。

海洋生态价值的特点:

1.海洋生态价值是一个历史范畴

2.海洋生态价值的主体整体性

3.海洋生态价值的全球连锁性

4.海洋生态价值的矛盾复杂性

5.海洋生态价值的整体有用性

6.海洋生态价值研究的战略紧迫性

6. 海洋生态环境保护论文

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.

海洋污染英语作文六: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

9. 海洋生态环境破坏最为严重的海区是哪一个

1、热污染和固体废物。主要包括工业冷却水和工程残土、垃圾及疏浚泥等。前者入海后能提高局部海区的水温,使溶解氧的含量降低 ,影响生物的新陈代谢,甚至使生物群落发生改变;后者可破坏海滨环境和海洋生物的栖息环境;

2、有机废液和生活污水。由径流带入海洋。极严重的可形成赤潮;

3、海滩开放的景点造成了许多垃圾的污染;

4、工业排出的热废水造成海洋的热污染,在局部海域,如有比原正常水温高出4摄氏度以上的热废水常年流入时,就会产生热污染,将破坏生态平衡和减少水中溶解氧;

5、农药。主要由径流带入海洋。对海洋生物有危害;

6、放射性物质。主要来自核爆炸、核工业或核舰艇的排污;

7、金属和酸、碱。包括铬、锰、铁、铜、锌、银、镉、锑、汞、铅等金属,磷、砷等非金属,以及酸和碱等。它们直接危害海洋生物的生存和影响其利用价值。

10. 海洋生态环境保护

11. 海洋生态环境面临的挑战

一)全球气候变暖。二氧化碳、甲烷等温室气体阻止地球表面热量散发,气候变暖引起两极冰川融化,导致海平面上升,使沿海地区受淹。

(二)臭氧层被破坏。臭氧层能吸收太阳紫外线。人类工业和生活活动中排放的臭氧层损耗物质会破坏臭氧层,导致人类皮肤癌和白内障的发病率升高。

(三)生物多样性减少。主要原因是过度捕猎、工业污染等。生物多样性的减少将逐渐瓦解人类生存的基础。

(四)酸雨蔓延。大量二氧化硫和氮氧化物等排入大气,在降雨时溶解在水中,即形成酸雨。酸雨具有腐蚀性,会损害农作物,导致湖泊酸化,鱼类死亡。

(五)森林锐减。人类的过度采伐,加上森林火灾,使得森林面积锐减。森林减少导致水土流失、洪灾频繁等恶果。

(六)土地荒漠化。过度放牧、采矿、修路等人类活动使草地退化。目前,全球荒漠化土地面积几乎相当于俄罗斯、加拿大、美国和中国国土面积的总和。

(七)资源短缺。其中最严重的是水资源、耕地资源和矿产资源短缺。目前全球约1/2人口受到缺水的威胁。工业、城市建设工程在不断占用耕地,这使人类正面临耕地不足的困境。

(八)水环境污染严重。工业污水使得原本清澈的水体变黑发臭,细菌滋生。在我国,七大水系的水源只有不到30%能达到饮用水水源的水质标准。

(九)大气污染。悬浮颗粒被人体吸入,容易引起呼吸道疾病。二级空气标准适合人类生活,但我国目前只有1/3的城市一年中绝大多数天数空气能达到二级标准。

(十)固体废弃物成灾。固体废弃物包括城市垃圾和工业固体废弃物。垃圾中含有有害物质,任意堆放会污染周围空气、水体,甚至地下水。
