About this title

Synopsis:

江河湖泊像一条条美丽的彩带装点着地球,这些美丽神奇的地方,总是令人向往。王海娜编著的这本《地球的耀眼明珠》系统地介绍了世界范围内有代表性的江河湖泊。《科普乐园:地球的耀眼明珠》通过惊险刺激的探险故事,严谨而生动的语言,栩栩如生的图片,详尽介绍了有关江河湖泊的科学知识,内容丰富,资料翔实。《科普乐园》通过两个小主人公妙趣横生的提问和博士爷爷机智巧妙的解答,使得抽象生涩的科学知识形象生动地展现在读者面前。丛书故事设计精巧,内容丰富多彩,语言通俗易懂,有利于激发读者的阅读兴趣,提高科学素养。王海娜编著的这本《地球的耀眼明珠》就是《科普乐园》系列丛书之一,主要以通俗生动的语言,介绍了世界范围内有代表性的江河湖泊。河流概述路上休息时,当当两眼直直地盯着叮叮的脸,叮叮以为自己脸上有什么东西,赶紧用手去摸了摸,啥也没有!可当当还是盯着不放,这下叮叮不干了,瞪着当当喊道:"小尾巴,我脸上有花吗?"当当这才意识到自己的失态,脸一红忙说:"我--我是在想,同是河流,为什么有的叫江,有的叫河呢?是因为大小的关系吗?""哦--"叮叮这才松了一口气,摸了摸头上的小豆芽,说:"是啊,有的河流叫江,有的叫河,有的叫沟,有的河流还叫涧呢!为什么这么叫,咱们查查资料吧!"河流是陆地表面经常或间歇有水流动的线形天然水道,是由一定区域内地表水和地下水补给,经常或间歇地沿着狭长凹地流动的水流;是地球上水文循环的重要路径,是泥沙、盐类和化学元素等进入湖泊、海洋的通道。每条河流都有河源和河口。河源是指河流的发源地,有的是泉水,有的是湖泊、沼泽或是冰川,各河河源情况不尽一样。河口是河流的终点,即河流流入海洋、河流(如支流流入干流)、湖泊或沼泽的地方。在干旱的沙漠区,有些河流河水沿途消耗于渗漏和蒸发,最后消失在沙漠中,这种河流称为瞎尾河。除河源和河口外,每一条河流根据水文和河谷地形特征分上中下游三段。上游比降大,流速大,冲刷占优势,河槽多为基岩或砾石;中游比降和流速减小,流量加大,冲刷、淤积都不严重,但河流侧蚀有所发展,河槽多为粗砂;下游比降平缓,流速较小,但流量大,淤积占优势,多浅滩或沙洲,河槽多细砂或淤泥。通常大江大河在人海处都会分多条人海,形成河口三角洲。通常把流人海洋的河流称为外流河,流入内陆湖泊或消失于沙漠之中的这类瞎尾河称为内流河。河流与人类的关系极为密切,因为河流暴露在地表,河水取用方便,是人类可依赖的最主要的淡水资源,也是可更新的能源。河流在中国的称谓很多,较大的称江、河、川、水,较小的称溪、涧、沟、曲等。我国流域面积超过100平方千米的河流有5万条,超过1000平方千米的河流有1500余条,超过1万平方千米的约有79条。天然河道总长约43万千米。虽然河流众多,但地区分布不均衡,河网密度自东南向西北递减。东南部河流多而且长,夏季容易形成汛期。秦岭和淮河一线以北的河流较少,且冬季河流结冰,普遍形成枯水期,一些河流甚至断流。由于沿途多沙漠和戈壁,蒸发和渗漏严重,西北内陆河更少,而且很多河流成为季节性河道。中国许多河流的含沙量、输沙量较大。全国每年的输沙量超过1000万吨的河流有42条,黄河陕县站多年平均输沙量为16亿吨。中国水力资源丰富,水力蕴藏量为6
