湿地

The Sanjiang Plain is a vast area of alluvial floodplains and low hills in northeast Heilongjiang Province. It is the largest tract of wetlands in China and East Asia outside of Siberia.

三江平原是黑龙江省东北部由冲积平原和低山组成的广袤区域，它是中国和东亚最大的一片湿地。

The absorbability of wetland plants on nitrogen and phosphorus was investigated by means of nutrient solution incubation.

用营养液培养方法研究了11种湿地植物对氮、磷的吸收能力。

Bacteria had the largest proportion in the community,followed by actinomyces and fungi.

湿地的土壤细菌、放线菌以及微生物的总数在8月达到最小，而真菌数量在7月达到最小。

Soil bacteria,actinomyces and total microbial reached the lowest values in August,but fungi in July.

湿地土壤中，细菌数量最大，其次是放线菌，最少的是真菌。

The quantity of actinomyces and their percentages followed that of bacteria,while the percentages decreased g...

这是由于盘锦芦苇湿地的土壤偏盐碱性，有利于细菌和放线菌繁殖，抑制了真菌的繁殖；而且季节性积水导致通气状况不良也抑制了真菌的生存。

Wetland plants have a series of physiological and anatomical characteristics to adapt flooding habitat, e.g., their root aerenchyma and oxygen-penetrating capability can make the rhizospheric micro-environment be under oxidation condition, resulting in the formation of Fe/Mn plaques on root surface.

湿地植物具有一系列生理和结构上适应浸水环境的特征，如根系的通气组织和渗氧能力，这使得植物根际微环境处于氧化状态，这样土壤中的铁和锰会在植物根表被氧化而形成红棕色的铁锰氧化物胶膜。

During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

This thirst for water is so pervasive that many wetlands considered to be hemispheric reserves for waterbirds have been heavily affected; for example, the California and Nevada wetlands in North America, the Macquarie Marshes in Australia, and the Aral Sea in central Asia.

对水的渴望是相当普遍的，保有地球储量半数水鸟的一些湿地受到了严重影响；例如，北美的加利福尼亚州和内华达州湿地，澳大利亚的麦克夸利河沼泽，位于亚洲中心的咸海。

The wetland area is one of the last open spaces near San Juan 's community of Catano.

这块湿地是圣胡安周边地区 Catano 最后开放的湿地之一。

This paper presents the primary study of wetland ecosystem's value of Poyang Lake with the methodologies of eco-economics and resource Economics.

湿地是具有多功能的生态系统，对其服务功能进行评估是湿地保护与合理开发的基础。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
