湿地的

Due to habitant diversity, Guandu wetland has played a crucial role in migration of birds from East Asia.

关渡湿地多样的栖息环境，在东亚候鸟迁移的国际航线上，一直扮演著相当重要的角色。

This coastal wetland, covered by the sea at high tide, is home to some 3,200 different animals and a popular stopover for many migratory birds.

这沿海湿地，被覆盖的大海处于高潮中，有一些3200种不同的动物和一种受欢迎的中途停留许多候鸟。

The following conclusions have been made in this paper.(1) Based on CO_2 flux data of eddy covariance, variation characteristics of gross primary productivity in four flux observation stations were studied, which are an alpine meadow, an alpine shrub meadow, a swamp alpine meadow and a steppe alpine meadow at Dongxiong. The results show that photosynthetic capacity of the alpine meadow is the highest, and the annual total GPP is 652.2g C/m~2. Daily-differencing approach is used to analyze the random error of CO_2 fluxes measurements. The results show that the distribution of random error follows more closely follows a double-exponential, rather than a normal distribution, capturing the high peak and thick tail, and the random error varies with environment variables, which violates the assumptions for the ordinary least squares fitting with normality and homoscedasticity, consequently, we introduce maximum likelihood method for parameter optimization.

本文主要在以下几个方面开展工作并获得了一些认知和结论：(1)通过分析样带区域内高寒草甸、高寒灌丛、沼泽化湿地和草原化高寒草甸四个通量观测站点草地生态系统总初级生产力变化特征，研究结果表明HBBT矮嵩草草甸生态系统植被光合作用能力较强，年GPP总量为652.2 gC/m~2，明显高于其他三种生态系统；通过利用"单塔日变化法"获得四站点通量观测数据随机误差，结果表明通量观测随机误差概率分布呈现尖峰厚尾的特征，与正态分布相比，更服从双边指数分布，进一步分析表明通量观测随机误差随环境变量(风速、温度和光合有效辐射)的变化而变化，这违背了普通最小二乘法进行生态过程模型参数优化正态分布且误差同质的假设，因此本研究中引入最大似然法进行生态过程模型参数优化。

In the wetlands of Moulting Lagoon, just outside Freycinet, you can watch black swans, pelicans, and pied oyster catchers wake to a new day.

在离菲欣纳不远的摩尔廷泻湖的湿地，您可以看到黑天鹅、鹈鹕以及斑蛎鹬醒来开始全新的一天。

As human population increase, the inter-tidal mudflat and salt marshes of the Eastern Tidelands of Chongming Island were reclaimed as large as 8000 hectares during last five years.

随着人类活动的增加，崇明东滩自然保护区内已被破坏或改变栖息地利用方式的湿地面积已达到8000公顷，在崇明逗留、栖息和越冬的鸟类也逐年减少。

Wetland is a unique ecosystem that has multifunction in the world, and is one of the most important living environments for human beings.

湿地是地球上具有多功能的、独特的生态系统，是人类最重要的生存环境之一。

According to the principles of total economic value, the first step of the evaluation of assets value of wetland is to classify the assets value into two categories: use value and nonuse value , the former include direct use value and indirect use values , and the later includes existence value and Bequest value , the option value belongs to non-use value because its use value can not be realized.

对湿地资源资产价值的核算，应根据总经济价值的原理，首先将其资产价值分为使用价值和非使用价值两大类；使用价值又进一步分为直接使用价值和间接使用价值；非使用价值则包括存在价值和遗产价值；选择价值由于目前无法实现其使用价值，因此属于非使用价值的范畴。

Wetland refers to natural or artificial, permanent or temporary marshes, peat bog and waters( motionless or flowing, fresh water or salt water) including sea area no deep than6 m in low tide.

湿地是指天然或人工的、久或暂时性的沼泽地、炭地和水域（静止或流动、水或咸水水体）包括低潮时水深浅于6米的海水区。

Wetland refers to natural or artificial, permanent or temporary marshes, peat bog and waters(motionless or flowing, fresh water or salt water) including sea area no deep than 6m in low tide.

湿地是指天然或人工的、永久或暂时性的沼泽地、泥炭地和水域（有静止或流动、淡水或咸水水体），包括低潮时水深浅于6米的海水区。

The term salar is used exclusively of the saltwater wetlands of the Puna and can describe not only salt lakes but also temporary marshes, shallow lakes and lagoons,or simply salt crust.

盐湖并不仅仅指安第斯山间高原的含盐湿地，也包括泻湖、浅的淡水湖等临时性沼泽地，甚至包括完全干涸的盐壳。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
