妈祖崇拜与海洋文化发展的关系 ：
妈祖与海洋文化发展的关系 中国沿海各省包括台湾,百姓皆以海事为他们工作的主轴,频繁的海事活动使中国人真正认识到大海的伟大,从心理产生了崇拜海洋的.情结,这种感情抒发于信仰领域,便成了航海保护神的崇拜--妈祖信仰.妈祖信仰早期的传播,发生在湄洲岛对面的大陆沿岸,传播的主要力量来自民间.福建概分为内陆山地和沿海平原两个区域,沿海狭长的平原可以视为四个由山脉走向形成的河流流域分割开的四部分,除了海上的交通之外,水系提供了福建省内运输网的支架,而妈祖信仰就是因为莆田海滨海域的有效开发,妈祖的信仰才逐渐伸展,而演变成至今的国际性、传统性的民间信仰.

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
6. 海洋生态学论文
首先，水是任何生物体都不可缺少的重要组成成分，生物体的含水量一般为60～80％，有些生物可达90％以上（如水母、蝌蚪等），从这个意义上说，没有水就没有生命。其次，生物的一切代谢活动都必须以水为介质，生物体内营养的运输、废物的排除、激素的传递以及生命赖以存在的各种生物化学过程，都必须在水溶液中才能进行，而所有物质也都必须以溶解状态才能出入细胞，所以在生物体和它们的环境之间时时刻刻都在进行着水交换。 各种生物之所以能够生存至今，都有赖于水的一种特性，即在3.98℃时密度最大。水的这一特殊性质使任何水体都不会同时全部冻结，当水温降到 3.98℃以下时，冷水总是在水体的表层而暖水在底层，因此结冰过程总是从上到下进行，这对历史上的冰河时期和现今寒冷地区生物的生存和延续来说是至关重要的。此外，水的热容量很大，而且吸热和放热是一个缓慢的过程，因此水体温度不像大气温度那样变化剧烈，也较少受气温波动的影响，这样，水就为生物创造了一个非常稳定的温度环境。 生物起源于水环境，生物进化90％的时间都是在海洋中进行的。生物登陆后所面临的主要问题是如何减少水分蒸发和保持体内的水分平衡。至今，完全适应在干燥陆地生活的只有像高等植物、昆虫、爬行动物、鸟类和哺乳动物这样一些生物，因为它们的表皮和皮肤基本是干燥和不透水的，而且在获取更多的水、减少水的消耗和贮存水三个方面都具有特殊的适应。水对陆生生物的热量调节和热能代谢也具有重要意义，因为蒸发散热是所有陆生生物降低体温的最重要手段。

8. 关于海洋生态的问题
如果污染超过了海洋生态系统的自我调节能力或者说自净能力，它就很难恢复到原来的状态。
生态系统保持自身稳定的能力被称为生态系统的自我调节能力。生态系统自我调节能力的强弱是多方因素共同作用体现的。一般地：成分多样、能量流动和物质循环途径复杂的生态系统自我调节能力强；反之，结构与成分单一的生态系统自我调节能力就相对更弱。热带雨林生态系统有着最为多样的成分和生态途径，因而也是最为稳定和复杂的生态系统，北极苔原生态系统由于仅地衣一种生产者，因而十分脆弱，被破坏后想要恢复便需花费很大代价。
