湖泊的

S a main source and sink of nitrogen from lake wetland ecosystem, lake sediment has an important significance for biogeochemical cycle of nitrogen.

bstract 湖泊底泥作为湖泊湿地生态系统中氮素的主要源与汇，对氮素的生物地球化学循环具有重要意义。

In some cases, some metals in sediments could be released into the overlying water, causing second pollution, and become a"chemical bomb"hiding under lake water.

另外，在一定条件下，沉积物中部分金属元素也可再次向上覆水体释放，造成"二次污染"问题，严重威胁到湖泊／水库的水质安全，成为埋藏在湖泊深处的一颗"定时炸弹"。

Water areas. Thus, it will improve the environmental research to study the sampling technology of gravity corer.

重力取样器是获取湖泊、水库等水域浅层湖泊沉积物的一种经济有效、操作简单的常用工具。

Therefore, fish's predatory control on zooplankton is higher in shallow lakes, resulting in less possibility of grazer control of algae by the Cladocera.

下行效应在浅水湖泊中可能更为重要，因此浅水湖泊中滤食性鱼类对浮游动物的捕食控制可能更强，导致枝角类几乎不可能通过牧食控制藻类的生长。

China is a country with abundant lake tourism resources. It is significantly important to project and develop take tourism resources.

中国是一个湖泊旅游资源大国，做好湖泊旅游资源的开发设计意义非同寻常。

Its tropical waters teem with more fish species than any other lake.

生活在这个热带湖泊里的鱼类比其它湖泊都要丰富

The eutrophication of Taihu lake is a representative ecological problem, so it can be controlled by some ecological control countermeasures, such as resuming aquicolous vegetation, restricting the area of breed aquatics in the Taihu lake, biologically manipulating alga, building ecological agriculture section around the Taihu lake and resuming the zoology of Taihu bank .

太湖富营养化是典型的生态问题，因此可通过恢复湖泊水生植被，限制湖泊网围养殖面积，实施生物操纵控藻，建设环湖生态农业区，恢复湖滨带生态等生态防治对策加以控制。

The region an area of 12,480 square kilometers, an elevation of 1300-1600 meters, the North South high-low, relatively flat terrain, vast grasslands, many inland lakes, Gang Liang, lakes, beaches and grass, marsh phase distribution, is a typical wavy plateau landscape.

该区域面积为12480平方公里，海拔1300-1600米，南高北低，地势较平坦，草原广阔，多内陆湖泊，岗梁、湖泊、滩地和草坡、草滩相间分布，是典型的波状高原景观。

And corresponding bio-control of lake eutrophication was also described to gradually remediate natural eco-environment of lake.

文中探讨了治理湖泊富营养化，逐步修复湖泊自然生态环境应采取的对策。

Results indicated that CO2 flux of Zhalong Lake, Long Lake, Keqin Lake and Dongsheng Reservoir were 13.57±3.45, 17.86±1.80, 18.48±0.83, and (18.32±3.59) mgm^(-2)h^(-1), respectively, and the mean flux was (16.79±2.55) mgm^(-2)h^(-1), which was close to the CO2 flux of lakes and reservoirs in temperate zone, but lower than those of lakes and reservoirs in subtropical and tropical zones.

结果表明：扎龙湖、龙湖、克钦湖和东升水库CO2通量分别为13.57±3.45、17.86±1.80、18.48±0.83和(18.32±3.59)mgm^(-2)h^(-1)，平均为16.79mgm^(-2)h^(-1)，与北方温带湖泊水库排放通量相近，但明显低于亚热带和热带地区的湖泊水库。

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

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
