这表明湿地植物的选择不仅要考查其对污染物的吸收速率，更要关注其对污染物的吸收容量，并且湿地植物的吸收作用对类二级出水中氮、磷的去除具有更加重要的意义。

Some water samples from intakes and outlets of 3 wetland pond beds growing Phragmites communis Trin, Typha angustifolia and Cyperus alternifolius were respectively taken for monitoring and contrasting 5 main water quality indexes including dissolved oxygen, chemical oxygen demand, biochemical oxygen demand in 5 days (BOD5), total nitrogen, and total phosphorus month by month all year around, so as to discover influences of different plant species on water purification efficiency.

摘 要：通过对成都活水公园人工湿地中的3种优势挺水植物所在塘床进出水口的5个主要水质指标：水中溶解氧（dissolved oxygen， DO）、化学需氧量（chemical oxygen demand， CODcr）、5日生化耗氧量（biochemical oxygen demand in 5 days， BOD5）、总氮（total nitrogen， TN）、总磷（total phosphorus， TP）的全年逐月对比监测，探索不同植物种类对污水净化效率的影响，并对湿地中不同植物塘净化效率产生差异的原因作了较全面的分析讨论。

The conception and function of groundcover plants are stated briefly in this article. According to the application principles of these plants in Xixi National Wetland Park of Hangzhou, the application state is introduced in details and landscape effect after the construction is concisely analyzed.

在简要阐述地被植物的含义及作用的基础上，根据杭州西溪国家湿地公园在实施保护过程中所遵循的地被植物应用原则，对建成后的西溪湿地地被植物的应用现状进行了详细的介绍，并对其景观效果进行了简要分析。

The comparation of the treatment between the microcosms with plants and without plants was also considered.

结果表明：(1)植物生长过程中，植物高度能反映污水处理效果总体仁的变化；(2)在植物的生长过程中，各人工湿地系统污水处理能力总体上持续增强，各水质指标pH、DO、TN、NH3-N、NO3-N、TP和COD等均呈下降趋势，其中TP和COD呈逐步下降，pH、DO、TN、NH3-N、NO3-N则呈现锯齿形波动，但总体上仍是下降过程；(3)植物系统氮处理能力好于无植物沙滤系统，而对磷TP和COD的去除则恰好相反；(4)不同植物对人工湿地污水的处理效果影响不明显。

General layout: General idea should focus on protecting urban water sources, restoring riverways, wetlands and groundwater, improving the water body function, strengthening water resources allocation and water function regions management. Based on existing water project structures, the generallayout follows as that urban water sources conservation on the upriver, wetland and groundwater restoration on mid-river and coastal wetland and estuarine eco-area restoration on the downriver, achieve the target that rivers and lakes 'connection, green bank, clean water, flowing river', then form aquaticecosystem protection and guarantee system.

以保护城市水源地为重点，以修复河道湿地、地下水和改善水体功能为核心，以强化水资源配置和水功能区管理为关键，基于现有的水利工程体系，在流域上游建立以城市饮用水水源地为主体的生态保护屏障，在流域中游建设以湖泊为点、河道为线、地下水为面的水生态修复系统，在流域下游构建以滨海湿地和入海河口为中心的生态恢复区，遏制水土流失，增强水源涵养，保护水功能区，实现河、湖&连通、绿岸、清水、流水&，进而形成防控结合的水生态环境保护与修复保障体系。

Lastly, the impact factors of methane flux are summarized, including biotic and abiotic factors.

湿地甲烷通量是由多种因素决定的，对影响湿地甲烷通量的因素的研究相当丰富，特别是近年来对生物因素的关注。

Upstream levee-building has also had the effect of turning a sluggish river into a fire hose, helping to destroy marshes and barrier islands that once provided some protection.

上游的河堤让受限的河水像枪管一样，导致了湿地及河中沙州的消失，而这些湿地及障岛沙洲事实上能提供更多的保护。

According to the models of land use dynamic change, the research on the dynamic change on land use quantity, space structure and land use degree were carried during 1989 and 2001. The results of the research indicated that the area of cultivated land and saline land increased, and the area of meadow, water areas and wetland reduced within 12 years; The variety ratio of cultivated land, meadow, water areas and saline land changed relatively great; and variety ratio of forestland, land used for resident, industrial and mining changed more steady; The land use degree presented a reducible tendency.

研究结果表明，吉林西部在12年内耕地和盐碱地面积增加，草地、水域和湿地面积减少；总体上，耕地、草地、水域和盐碱地的土地利用变化率较大，林地、居民、工矿用地和湿地变化较平稳； 12年间土地利用程度呈减小趋势，全区十个县市中只有白城和扶余的土地利用处于发展期，土地生态环境相对较好，而其他地区由于土地生态环境呈现不同程度的恶化，导致可开发利用的土地资源逐年较少，土地利用潜力小。
