查询词典 lake

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.

方法］以小瓜子、缎带椒、中柳、皇冠和西瓜草5种植物为试材，以北京市延庆县妫水湖8月份富营养化程度最高的湖水为植物生长基质，设高、中、低3个投放密度试验组，研究植物投放密度对富营养化湖水的修复效率影响；通过测定水样中总磷酸盐、总氮、氨氮和硝态氮的浓度变化，确定植物修复的最佳效率。

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)。
