湿地的

The author summarizes methods of achieving ET from wetland, for example, models of Thornthwaite, Penman Monteith, Prestley Taylor, Sanjiang Plain Swamp ,eddy correlation ,remote sensing and ...

通过总结国内外湿地蒸散量的测算方法，如Thornthwaite公式、Penman Monteith模型、Prestley Taylor模型、三江平原沼泽湿地蒸散经验模型、涡度相关法和遥感方法等，提出在湿地特定的自然条件下，经验模型法在湿地蒸散中的应用要比在其它陆地生态系统蒸散研究中的应用更为准确。

When big, moderate rain and rainstorm, the Y value size order is always the masson pine pinus elliottii mixed forest＜the wetland pinery＜the wetland pinery＜the locust tree forest＜the locust tree pinus elliottii mixed forest＜the thin forest, to the soil protection effect, the conifer forest is better than broad leaved forest. For annual rainfall erosion, the Y value ordered: Locust tree forest＜wetland pinery＜locust tree pinus elliottii mixed forest＜wetland pinery＜masson pine pinus elliottii mixed forest＜thin forest.

大、中雨和暴雨时，Y值的大小顺序都是马尾松湿地松混交林＜湿地松林＜湿地松林＜刺槐林＜刺槐湿地松混交林＜疏林，对土壤保护效果针叶林优于阔叶林；对于年降雨侵蚀，Y值的大小顺序是：刺槐林＜湿地松林＜刺槐湿地松混交林＜湿地松林＜马尾松湿地松混交林＜疏林。

The results show that:(1) wetland reservoirs can control wetland degeneration and springwater overflow;(2)wetland reservoirs can store floodwater and winter to prevent flood, drought and desertification so that keep ecological system balance of wetland;(3) uncoordinated contradiction between agricultural water use and ecological water demand can be resolved under the adjustable function of wetland reservoirs;(4)wetland reservoirs has effective capability to keep biological diversity.

对位于玛纳斯河流域泉水溢出带中的湿地水库群对流域生态环境的作用进行了研究，结果表明，该湿地水库群在防止湿地萎缩退化、防止次生盐渍化、保护流域内生物多样性、防风固沙、防止土壤沙化、抵御洪、旱灾害威胁、加强湿地调控能力以及增加了绿洲的人口承载能力和生产力等方面起到了很好的保护作用。

The plant community composition changed and the community coverage increased over the wetland succession from primary swamp, through swampy meadow, to meadow. The number of associated species increased, while the dominant species abundances decreased. Through succession, the content of soil organic matter and total nitrogen declined. In contrast, the soil enzyme activity of catalase, protease and invertase increased; however urase declined.

随着湿地原生沼泽向沼泽化草甸、草甸的演替，湿地植物群落盖度增加、物种组成增多，群落优势种优势度减小，伴生种数量增加，植物多样性呈增加趋势；湿地土壤有机质、全氮含量不断减少，过氧化氢酶、蛋白酶、蔗糖酶活性增加，脲酶活性降低。

First of all, according to analysis the effect of ecosystem during the water cycle, the type of ecological water demand in wetland was clarified which is an azonal ecological system supported by the runoff with the feature of azonal.

通过分析湿地水文循环的生态效应，湿地是由径流支撑的非地带性生态系统，具有泛区域特点，湿地生态需水须要在研究湿地径流场与生物多样性变化基础上进行。

However, people only pay great attention to short-term economic benefit, neglect ecological value and social value of the wetland, destroy wetland's ecological environment, finally caused harm on service function of wetland's ecosystem, leaded to the wetland'ecosystem to provide welfare for people decreasingly, directly threatened the ecological foundation of human sustainable development.

然而人们往往只注重近期的经济利益，忽略了湿地所具有的生态价值和社会价值，造成对湿地生态环境的严重破坏，最终导致湿地生态系统的服务功能受到损害，使湿地生态系统向人们提供的福利减少，直接威胁到人类可持续发展的生态基础。

According to the nature of the water sources, wetlands can be classified into six types: marine, estuarine, lacustrine, riverine, palustrine (found in marshes, swamps and bogs) and artificial.

按水源界别，湿地可分为六大类：海洋、河口三角洲、湖泊、河滨、淡水（位於沼泽、草泽及苔地的湿地）和人工湿地。

Seasonal variation of the distributions of microorganism in the root-zones of wetland plants (Phragmites australis, Zizania latifolia, Zizania latifolia etc.), the substrate layers of control SSPs, together with the effects of wastewater treatment were studied. The results are as follows: the numbers of microorganisms in the different plant root-zones were different; the purification effects were also different. The number of microorganisms in the substrate of the control plot becomes smaller with increasing depth. The numbers of bacteria in fall were higher than those in the summer for the three plant zones and the control, and the number of fungi and actinomyces in summer was much higher than that in the fall for control. As for fungi and actinomyces in the experimental systems, most of their difference between the summer and fall were not as big as that in the control.

通过对不同季节芦苇、茭白和香蒲等湿地系统植物根区、无植物对照基质微生物分布状况以及净化效果的研究，结果显示：（1）种植不同植物的湿地系统根区微生物数量不同，其湿地净化效果也不同；（2）对照系统微生物的数量随基质深度的增加而递减；（3）季节变化显示湿地系统秋季的细菌总数量比夏季高；但对照系统夏季的真菌和放线菌数量明显高于秋季；（4）湿地系统TP的去除率夏季高于秋季。

The Quanzhou Gulf is one of the major wetlands along the eastsouthern coast line of China. The specific wetland ecotourist landscape is involved with special geographical condition and with early human activities ,with multiple wetland types.

中文摘要：泉州湾湿地是我国东南沿海典型湿地类型之一，其特殊的地理、自然条件和人类长期活动形成独特的湿地旅游资源，湿地多样性明显，但也伴随人为强度干预导致的景观脆弱性。

It needs us to deal with the relationship of the WT and environment protection correctly, to define the threshold population of WT, to forecast environmental capacity of WT. For the sake of protection, the exploitations would do no harm to wetland environment.

这就要求我们正确处理湿地旅游发展和环境保护的关系，确定湿地旅游的门槛人口，预测湿地旅游环境容量，在开发和保护并重的基础上，不对湿地环境构成危害。

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
