世界湿地日World Wetlands Day英文介绍
好学英文网编者按:每年的2月2日是世界湿地日World Wetlands Day,这里给大家普及一下基本知识。
俗话说:“没有湿地也就没有水!”湿地与人类的生存、繁衍及发展息息相关。中国湿地约占世界湿地面积的10%,是世界上湿地生物多样性最丰富的国家之一。我国湿地资源还处于严重的威胁之中,主要是水资源不合理利用及农业开垦,导致湖泊数量不断减少,面积不断萎缩。同时,湿地上游水土流失,导致河床、湖底淤积严重。
February 2 each year is World Wetlands Day. It marks1 the signing of the international Convention (公约) on Wetlands in Ramsar, Iran, on 2 February 1971. There are many definitions2 of wetlands, but put simply, wetlands are usually wet. The three criteria3 used to deter- mine a wetland are: the presence of wet soil, water in the form of flooding or saturation (饱和), and vegetation(植被) or plants that grow in water.
World Wetlands Day has been celebrated since 1997 and provides an opportunity to draw attention to the need for wise management of the world's wetlands through a variety of events (活动) such as workshops (专题讨论会) and seminars4, nature walks and guided tours, children's art contests and photographic(摄影的) competitions, community clean-ups, planting activities or other local initiatives(倡议). The theme for World Wetlands Day 2005 is "Cultural and Biological Diversity(多样性) of Wetlands".
Functions and Values of Wetlands
Flood and Storm Water Damage Protection Wetlands act like sponges (海绵), slowing the slow of floods by temporarily storing flood and runoff(地表径流) waters.
Water Purification (净化) Pollutants (污染物) can be removed through absorption(吸收) by plants and soils.
Maintenance of Water Supply Wetlands can serve as groundwater recharging5 zones, improving the flow of streams.
Preservation of Wildlife Habitats Wetlands provide breeding, nesting(筑巢), rearing6 and wintering habitats for many fish and wildlife species. These include endangered (濒危的) species, such as whooping cranes (美洲鹤), bald eagles (秃鹰) and wood storks (黑头鹮鹳). Wetlands provide breeding grounds for fish and shellfish (有壳的水生动物) and are home for many species of timber(树木), for wild rice and cran- berries(越橘).
Climatic Influences Wetlands help control atmospheric pollution by removing excess nitrogen(氮) and carbon produced by humans. hxw.red
Recreation and Natural Beauty Places for hunting and fishing, canoeing(乘独木舟) and boating, nature study and photography and outdoor education are provided by wetlands.

每年的2月2日是世界湿地日。这是为了纪念1971年2月2日在伊朗拉姆萨尔签订的国际湿地公约。湿地有许多定义,但简而言之,湿地总是潮湿的。判定湿地的3个标准是:存在潮湿的土壤;被浅水淹没或处于水饱和状态;水生的植被或植物。
世界湿地日的活动始自1997年,从而提供了一个机会,通过各种活动引起人们对全球湿地需要进行科学管理这件事的重视。这些活动包括专题讨论会和研讨会,在大自然中漫步及有指导的旅游,儿童艺术比赛以及摄影竞赛,社区清理,植树活动或其他地区性的倡议。2005年世界湿地日的主题是“湿地的文化与生物多样性”。
湿地的功能和价值
抵御洪水和暴雨的破坏 湿地起到类似海绵的作用,通过暂时储蓄洪水和地表径流,减缓洪水的流动速度。
净化水质 植物和土壤的吸收能去除污染物。
保持水供给 湿地能起到地下水再补充区域的作用,加大河流的流量。
保护野生生物栖息地 湿地能为许多鱼类和野生生物提供繁殖、筑巢、养育和过冬的栖息地。这些动物包括一些濒危物种,例如美洲鹤、秃鹰和黑头鹮鹳。湿地为鱼类和贝类提供了繁育地,也是多种树木、野米(菰米)和越橘的家园。
影响气候 湿地可以去除由人类制造出来的过量氮元素和碳元素物质、从而有助于控制大气污染。
娱乐和美化大自然 湿地可以为狩猎、垂钓、驾独木舟或划船、自然研究以及摄影,还有户外教育等活动提供场所。
