湖泊水文湖泊水文hydrologic regime of lake相似的条件下，下垫面不均匀是形成气候差异的主要因素，因此湖陆间气候的差异即是不同下垫面作用的结果。湖泊对湖区气候的影响，称为湖泊气候效应。这种效应主要表现为增高近湖区的年平均气温，减小气温的年、日较差，以及增加湖区温度，使气候变得较远湖区稍微温和、湿润。如中国的抚仙湖南部小岛上的年平均气温比北部陆上高1.2℃，年较差小2.5℃，日较差小1.2℃。因此，湖区气候更适宜于人们的生产生活，其气候资源亦较远湖区丰富。湖泊对气候调节的程度和影响的范围，主要取决于湖面积的大小、湖水的深度和湖周的地形。一般来说大而深的湖泊，调节作用大、影响范围也广;地形封闭的湖泊，影响范围虽较小，但调节作用更为明显。湖泊与人类活动湖泊有航运、水产、发电、工农业给水和旅游等多种效益。人类在利用湖泊资源的同时，不断地影响、改造湖泊。如为充分发挥湖泊的调蓄功能，修筑闸坝，人工控制水量，为防止湖水泛滥，修筑湖堤;为利用湖滩地种植，围湖造田等等。但修筑湖闸，可堵塞某些鱼类的回游通道，影响湖鱼产量;盲目围垦，会加速湖泊消亡，在上游引水过多，减少了入湖水量，延长了湖水更换期，可使水质恶化，将工业废水、农业灌溉尾水和城市生活污水排放入湖，造成湖水污染(见水质评价)。此外，人们为了灌溉、发电等需要，拦河筑坝而形成水库，亦属湖泊之列(见水库)。huPo shuiwen湖泊水文(hydrologie regime of lake)湖水中的物理化学现象的发生、发展和变化。湖水物理现象是指湖泊水量平衡、水位升降、湖水运动、湖水光学、湖水热学与冰情等;化学现象则为湖水矿化度、硬度、主要离子、溶解气体、有机质以及微量元素等。早在二千多年以前，中国就开始对湖泊水文有所认识。公元前2以前的《禹贡》就记载着湖泊水文情况。从19开始洪泽湖就有了水位观测。20世纪60年代以后，结合湖泊综合调查，开展了湖泊水文研究。赫罗塔斯(I于erodotus)曾在438年记录了里海的水位情况。1892一1904年福雷尔(F.A.Forel)在他的关于日内瓦湖的三卷著作中，系统的阐述了湖泊水文特性。随着生产的发展，经济利用的需要，人们对湖泊水文的研究逐渐深入，认识不断深化。湖泊水量地球上湖泊蓄水量为176.4万亿立方米，占全球总水量的0.013%。其中淡水储量为91万亿立方米，占全球淡水总量的0.26%。湖泊淡水储量在地球上的分布很不均匀。北美、非洲和亚洲大陆上的湖泊约占70%。北美苏必利尔等五大淡水湖群约占24%。世界著名湖泊列于表I。
