湖泊

Wetlands could be classified into 6 types that they are marine, estuarine, lacustrine, riverine wetlands along rivers and streams, palustrine (wetlands in marshes, swamps and bogs and artificial.

湿地可分为6大类──海洋、河口三角洲、湖泊（包括与湖泊有关连的湿地）、河滨（包括与河溪相关连的湿地）、淡水（包括位於沼泽、草泽及苔地的湿地）和人工湿地。

Internal nutrient loading caused by sediment resuspension is becoming a key issue in studying water eutrophication of shallow lakes.

再悬浮过程中沉积物对水体营养盐的内源贡献是湖泊，特别是浅水湖泊富营养化研究中的重要问题。

In modern researches on the grain-size characteristics of lake sediments, the methods of incertical dividing sediments grain-size have no rigorous mathematical theory to support. To resolve this omission, the case of pollen zonation was taken for reference. 338 samples measured by Mastersizer 2000 from DG02 core of Gahai lake in Qaidam Basin were studied. Considering the clustering results of sequential clusters did not change the sequence of samples, tilia software package was used to divide the dividing sediments grain-size.

针对现阶段湖泊沉积物粒度特征研究中垂直剖面分层方法所存在的数学方法的不足，借鉴孢粉分带比较成熟的案例，应用有序聚类法中次序不变的特点，以柴达木盆地尕海湖DG02钻孔338个经激光粒度仪测试的样品为研究对象，在有序聚类的数学理论基础上，借助Tilia软件将湖泊沉积物垂直剖面进行分层。

Many small lakes in Ethiopia and several long narrow lakes, notably lakes Turkana and Nyasa, lie on its course.

埃塞俄比亚的许多湖泊和几个狭长的小湖泊，尤其是图尔卡纳湖和尼亚萨湖。

The results showed that pH of the irradiated sediment core is higher than the unsterilized one,and microorganisms could have an effect on the pH of sediments.All the four sediments are in the strong reductive environment at the depth of 7～30 cm,and the values of Eh are quite closer,the main factor that affect the redox environment may be the compaction of the sediment.All the sediments had a cumulation of phosphorus at the surface layer,and the total phosphorus of the sediments at the depth of 4～10 cm are lower than the average.It is indicated that phosphorus had been redistributed at the suface layer.

本研究采集太湖梅梁湾沉积物，通过印Co.y射线辐照、添加可溶性淀粉等处理研究微生物活性对太湖沉积物pH，Eh及总磷分布影响，以揭示微生物在湖泊沉积物中的沉积后作用，为探索富营养化湖泊表层沉积物磷的归趋提供理论基础。1 材料与方法1.1 样品采集和处理2005年1 1月，采用自制的柱状采泥器采集太湖梅梁湾沉积物，采样位点为31.30.306 N.120.13.370 E，采集后立即带回实验室，其理化性质见表1。

Diaojiaohaizi is a thoroughly closed basaltic depression lake on the top of Daqing mountains which has many advantages when it is used in studding vegetational evolution and climatic changes of the Holocene.

调角海子为大青山顶部的一个全封闭的玄武岩洼地湖泊，冰后期积水成湖，其湖泊沉积物具有用来研究全新世植被和气候变化的许多独特优点。

The effects of different types of aquaculture on lake ecosystems were studied by monitoring plankton, zoobenthos ,aquatic plants and water quality in 60 lakes in Suzhou City.

通过对苏州市60个湖泊的浮游生物、底栖动物、水生植物及水质的监测，分析不同养殖方式下湖泊生态系统的差异。

On such a basis, it concretely discusses the effects of the cultivation on ecological environment and holds the view that the damage of the original hydro geological environment by over-cultivation in South-East China results in the serious situation of "no reservation of water and no irrigation when drought" and thus greatly increases difficulties in flood prevention. Local governments through ages act on their own way without cooperation among diked paddy-fields in different areas and therefore local floods take place every year due to breakdown of the dikes. The great shrinking of lake areas because of too much reclamation affects the function of lakes in adjusting water volume and destroys ecological conditions of the area, leads to frequent disasters.

在此基础上，具体探讨了圩田开发对生态环境所造成的影响，认为因过渡围垦破坏了江南地区原有的湖泊河流水文环境，造成&水不得停蓄，旱不得流注&的严重局面，这便给圩田大大增加了防患水灾的压力；历代地方政府在圩田管理方面也是各自为政，各地圩田缺乏相互间的协作，使因破圩而形成的局部水灾年年有之；大量构筑圩田，使湖泊面积大为缩小，影响其调节水量的功能，破坏了本地区的生态条件，致使灾害频频发生。

Results The damp fans, rivers and lakes are main sedimentary systems in Yanqi Basin. They are funned from T(subscript 2-3) to J2, including Xiaoquangou, Badaowan, Sangonghe, Xishanyao and Toutunhe age. The rivers and lakes sedimentary systems are good development. The rivers sedimentary systems are divided into braided stream and meandering stream.

结果 潮湿扇、河流和湖泊沉积体系是焉耆盆地的主要沉积体系类型，它们形成于中晚三叠世至中侏罗世的小泉沟、八道湾、三工河、西山窑和头屯河期；其中的河流沉积体系和湖泊沉积体系较为发育，河流沉积体系分为辫状河和曲流河两种类型。

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