蒸发量观测蒸发量观测observation of evaporation 入土中和地面_L二种,中国通用的E一601型蒸发器和苏联rrH一3000型蒸发器属于前者,中国沿用的口径80厘米和20厘米的蒸发器皿及美国A型蒸发器属于地面式的。漂浮水面蒸发场地应设于靠近地形开旷的岸边水面上。观测蒸发量,是测针量测,或用加水的方法使水面保持在某一定点,量计所加水量。本日蒸发量为本日和次日8时实测蒸发器水面高度之差(或所加水深)加上雨量器同时测得的降水量的改正而得出的水层深。由于蒸发器与实际水体的自然条件不同,器测的蒸发量一般均大于自然的水面蒸发,且随器皿的形式、安装方式和不同季节而异,因而必须将器测蒸发量乘以折算系数才可作为水面蒸发量。折算系数是蒸发池和蒸发器所测蒸发量之比值,一般将大型蒸发池观测的蒸发量近似地作为水面蒸发量。封冻期使用20厘米蒸发皿,用称重法观测一日或几日的冰面累计蒸发总量。雪面蒸发,也用’J、蒸发皿以称重法进行观测。 蒸散发观测是为满足研究流域水量平衡和农作物需水量等目的。观测的陆面蒸散发值和裸露土壤蒸发值之差,作为观测的植物散发量,直接观测土壤蒸发和陆面蒸散发,多用土壤蒸发器或蒸渗仪(包括潜水蒸发器),其结构型式和仪器的大小,要根据耕作土地的类型、土壤特性及其含水程度等因素选定。蒸发量的观测方法,一般可区分为直接称重式(普通机械称重和基于浮力原理的水力称重)和体积量水式两种。目前国际上还没有一种通用的土壤蒸发器和蒸渗仪。一般公认水力式土壤蒸发器和蒸渗仪(面积0.2和0.3平方米、深度为1 .5米一3米)以及苏联使用的大型水力式蒸发器(面积5平方米、深2米)是较为先进和精确的蒸发器。中国在一些实验站上分别观测使用苏联的rrH一500型土壤蒸发器和小型水力式蒸发器,也设计建造了各种类型的潜水蒸发器,对平原地区的浅层地下水的蒸发现象进行观测研究(见蒸渗仪)。zhengfaliang guanee蒸发量观Mll(observation of eVapora-tion)水面蒸发、蒸散发等要素的观测和记录。后者包括土壤蒸发和植物散发。通常多采用蒸发器直接观测,或根据蒸发控制因素的观测资料进行间接推算。蒸发量以毫米计,测记至0.1毫米。 水面蒸发是水库、湖泊等水体水量损失的一部分,同时也损失热能源。水面蒸发观测是为了探索水体的水面蒸发在不同地区和时间上的分布规律,为水文水利计算和科学研究提供依据。按观测场的设置方式可分成两种:一种是在陆上水面蒸发场上安设蒸发器进行观测;另一种是漂浮水面蒸发场,即在水体中设置浮筏并在上面架设浮在水面的蒸发器观测蒸发量。陆上水面蒸发场地四周应空旷平坦,避开局部地形、建筑物及树林等障碍物的影响。蒸发器的安设方式,有埋
