湿地

Each HGMU has similar ecological functions, and different HGMU has clear different ecological functions. Among these HGMUs, the double direction of freshwater\|flooding area, daily tide\|mud and sand flat area and monthly tide\|mudflat, as well as annual tide\|grass flat area had better ecological functions than other areas in the coastal wetlands of Yancheng.

结果表明：（1）盐城海滨湿地包括7类水文地貌单元，不同HGMU生态系统类型差异较大；（2）同种HGMU生态功能基本处于同一等级，不同HGMU的生态功能差异明显；（3）盐城海滨湿地不同HGMU单元生态功能由大到小排序为：淡水双向\|冲积区、海水天双向\|泥粉砂带、海水月双向\|泥滩带、海水年双向\|草滩带、淡水单向\|冲积区、淡水单向\|海积区和淡水单向\|冲积海积区。

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。

All this, in turn, lends urgency to plans proposed by Louisiana politicians to restore natural hurricane protections by diverting water and silt from the river to coastal marshes and wetlands, and by rebuilding barrier islands.

总结以上，最迫切的是需要Louisiana的政治家，重新建造让河水自然的分流、淤塞的海岸湿地，重新出现障岛沙洲，这需要超过四十年的时间及140亿以上的花费、八十亿的湿地恢复计画。

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。

In present work, the economic and institutional cause of wetland degradations based on the approach and theories of environment economics and institution economics have been discussed and analyses.

Two-fifths of the country's rich mudflats, or about 1,600 square kilometres, mainly on the peninsula's west coast, have been "reclaimed".

韩国丰富的湿地有2/5，大概1600平方公里，已用于建筑开发。这些开发的湿地大多在朝鲜半岛西岸。

The flux rate of methane emission from the peatland in Qinghai-Tibet highland and the freshwater marsh in Sanjiang plain ranged from 0.16 to 10.0 mg CH4 m-2 h-1 with an average of 2.96 mg CH4 m-2 h-1 and 0.16-54.6 mg CH4 m-2 h-1 with an average of 19.6 mg CH4 m-2 h-1, respectively.

依据本研究野外实际测定的甲烷排放通量和前人已有的研究结果，初步估算了我国沼泽湿地甲烷年排放总量为1.76Tg ，占全球沼泽湿地甲烷排放总量68Tg 的2.59%。

The split between the two groups can hardly be papered over.
