湿地

The results showed that the significant level of impact on soil was increased with the increasing of grazing intensity.

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。

At present,some countries in the world especially the Japan focus its emphasis of ecological system protection on the wetland protection,and put forward and implement some countermeasures to protect and restore biological habitant with a certain effectiveness,which can be used for reference.

在自然环境的保护中，目前最迫切的是保护各类物种的生息地，特别是濒危物种的栖息地，如山林、湿地、河流、湖泊、岸边林、水田等。而我们所从事的水利工程建设可以说是对生物栖息环境影响最大的人类活动，但是大多数水

In the park, you can find heart-shaped wetlands.

在公园里，你可以找到心形的湿地。

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。

Kenli County, known as the broadest, the most complete, and the youngest wetland system in the warm temperate zone, is located at the mouth of Yellow River, the mother river of China, which carries alluvial deposits to create new land of 32.4 square kilometers every year. Meanwhile, the county holds rich oil and natural gas resources and ample seafoods such as holothurian. It also served as an important holy revolutionary base in 1940s.

山东省垦利县位于中华民族的母亲河——黄河的入海口，黄河每年携沙在垦利造陆三万亩左右，被誉为共和国最年轻的土地，拥有我国温带最年轻、最广阔、最完整的湿地生态系统；同时，垦利作为胜利油田的发祥地和主产矿区，地下油气资源富集；这里也是著名的红色革命老区，有山东的"小延安"之称；垦利濒临渤海，盛产海参、黄河口刀鱼等名优海产品，素有"百鱼之乡"、"黄金海岸"的美誉。

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。
