湿地的

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。

The percentage of Cyanide, phenol, mercury and chromium which have little effect on water quality is small and the variation tendency is slow. The percentage of Ammoniac azote, TP, TN, Cd, potassium permanganate index and fluoride which have much effect on water quality is big and the variation tendency is great. The percentage of DO, BOD5, petrochemical compounds and lead lies in the mean place between two guidelines above, which plays a normal role in contributing to the water quality of Yuehai, but the variation tendency is obvious.

选取了15个参数作为评价因素，其中，氰化物、挥发酚、汞、六价铬等指标的权重较小，对水质变化的总体影响不大，并且年度变化趋势较平缓；氨氮、总磷、总氮、镉、高锰酸盐指数以及氟化物等指标在阅海湿地水质总体评价中所占比重较大，直接影响水道水质；DO、BOD5、石油类、铅等指标的权重介于上述指标的中间。

Pedestrian walkways and water components neatly meander throughout the greenery, while the west-east directed canal forms generous lake surface and plaza space.

湿地、水渠与人行步道形成的三条简洁的主线交错穿梭于绿地之间，从地块西部的运河向东部会聚，形成大的湖面与广场空间。

Because of its special geological condition, it has allowed the establishment of some special microorganisms.

由于若尔盖高原湿地特殊的生态环境，为特殊的微生物种群的发育提供了条件。

One of the reasons they may be considered significant is that -- like tundra - peatlands store carbon and methane.

土地使用的改变和气候的变化可能造成泥灰地及沼泽湿地大量的排放这些温室气体。

In this paper, the status quo of China's wetland resources and the contradiction in protection and exploitation of wetland resources have been described and evaluated, and the positive role of nature reserve constr...

并就目前存在的主要问题，及进一步加强湿地生物多样性的保护和持续利用，提出了相应的对策与建议。

The results showed that the IVCW effectively removed total suspended solids(85%),chemical oxygen demand(50%),five-day biochemical oxygen demand(44%),total ammonia(53%),nitrite(83%) and nitrate(54%) from the aquaculture wastewater at a hydraulic loading rate of 420mm/d.

结果表明，在420 mm/d的水力负荷下，湿地可有效地去除循环水中的总悬浮物(去除率85%)、CODCr(去除率50%)、BOD5(去除率44%)、总氨氮(去除率53%)、亚硝酸盐(去除率83%)和硝酸盐(去除率54%)，能够满足养殖用水的要求，整个试验期间系统实现了零污水排放。
