By the budgetary estimate of the water and heat conditions at the glacial equilibrium line and the water balance of lakes in the area of the West Kunlun Mountains during the late stadial of the Last Glaciation. before the summer mean temperature decreased by 1.5 C, the annal mean precipitation was 10-20% more than that of the present. As the summer mean temperature lowering was over 1. 5 C, the precipitation was decreased and the negtive of the lake water balance appeared.

文中还根据对西昆仑山区冰川零平衡线处水热状况及湖泊水量平衡状况的推算，指出末次盛冰期中，在夏季温度降低1-1.5℃以前，其年降水量应大于现代值，增加量大约在10-20％左右；在夏季温度降低值大于1-1.5℃以后，其降水减少，湖泊水量平衡出现负值，这与冰川、湖泊变化的地质记录所反映的早期冷湿、中期冷干气候条件相符。

In this paper,dynamic changes of lacustrine water in the Sihu area were analyzed by using remote sensing.

采用遥感方法分析了四湖地区的湖泊水域的动态变化，分析结果表明：该地区 50年代至 80年代初由于大规模围湖造田，致使湖泊水域萎缩相当严重，80年代以后，湖泊水面急剧减少的趋势得到遏制，而 90年代以后，湖泊水面基本处于无显著变化状态。

Taking Wuliangsuhai Lake,which is a typical shallow weedy lake lies in Hetao irrigate district in the north of China,as a research object,combining the measured water quality data with the spatial data,using the method of Principal Components Analysis based on factor analysis,the water quality parameters of WL are summarized into seven principal components,namely the index ...

以位于我国北方的河套灌区中的草型浅水湖泊乌梁素海为研究对象，将实测的湖泊水质监测数据与空间数据结合，采用基于因子分析的主成分方法将乌梁素海的水质参数概括为7个主成分，即：富营养化特征指标、湖泊盐化特征指标、湖泊有机物污染指标、湖泊形态特征指标、水体酸碱指标、水体藻类生物量指标、植物生长环境指标。

This is different from previous researches, in which long-distance founder effect is the main force of phylogeography of rotifer population.

各湖泊隔离年代比较短，不同湖泊轮虫种群之间扩散强度大，轮虫休眠卵库的存在，以及近几十年来各湖泊环境条件变化可能是造成"有时滞基因流"产生的原因。

Data collected by a satellite launched in 2003 - the Ice, Cloud and Land Elevation Satellite, or ICESat - revealed a complex network of subglacial plumbing in which water periodically cascades from one hidden reservoir to another.

美国宇航局2003年发射的"冰云和地面高度卫星"收集的数据显示，南极冰层下有一个复杂的湖泊排水网络，湖水会周期性地从一个隐秘的湖泊流向另一个湖泊。

In May 2007, benefit city west lake began the ecosystem rehabilitate that with aquatic vegetation compose is built and fish adjusting control gives priority to and compose to build project, in order to control laky eutrophication, improve laky water quality.

梗概： 惠州南湖是典型的亚热带浅水城市湖泊。2007年5月，惠州西湖开展了以水生植被构建和鱼类调控为主的生态系统修复和构建工程，以控制湖泊富营养化，改善湖泊水质。

A relative low lake level between 8660～6010 cal.yr BPwas reflected by the clayey silt sediment with the median size less than 25μam and the sandcontent less than 4%,and the Pediastrum concentration was normally low.Between 6010 and2250 cal.yr BP,the median size and sand content increased greatly,and the Pediastrumconcentration raised sharply,suggesting a relative low lake level.After 2250 cal.yr BP,boththe median size and the Pediastrum abundance abruptly declined,suggesting the lake returnedto high level and the climate changed to humid.

UG04孔硅藻记录重建的湖泊水位变化基本上支持孢粉重建的古植被和古气候：8660～7230 cal.yr BP硅藻组合以浮游类主导，浮游／底栖比达40以上，指示水位较高，气候略湿润；7230～2330 cal.yr BP浮游类硅藻丰度和浮游／底栖比降低，湖泊处于低水位，气候干旱；2330～930 cal.yr BP浮游类硅藻丰度和浮游／底栖比增加，湖泊水位升高，气候湿润。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.(3) Comparing with the linking lake, Zhangdu Lake had higher fishing production, larger individual size, fewer species number and lower diversity index of "mihunzheng" fishery, a universal fishing tool in Yangtze.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30%；迷魂阵渔获物在单位产量、个体大小上极显著(p 0.01)地高于通江湖泊，但在物种数和多样性指数上则要低得多(p 0.01)。

The sedimentary environment divided in to fluvial deposit and lacustrine deposit. The sedimentary evolution of each depositional circle usually began with alluvial channel to fluvial deposit, and evolved into lacustrine deposit which is mainly made up of shore-shallow lake sedimentary model with relatively stirring hydrodynamic condition.

其沉积环境主要可以分为河流沉积和湖泊沉积两种类型，每一个沉积旋回都是以洪积扇到河流相沉积开始，向湖泊相沉积演化，湖泊沉积阶段主要以湖水相时动荡的滨浅湖沉积为主。
