这关键区别在实际的蒸散和潜在的蒸散量之间实际的蒸散量是实际从表面去除的水量蒸发andtranspirationwhile potential evapotranspiration is a measure of the ability of the气氛to remove water from the surface through蒸发andtranspiration。
足够的水是作物生长的一个关键因素d yield. Many crops are grown in environments that are naturally short of water. Hence, water resource management is an essential process in crop growth. Scientists consider both potential evapotranspiration and actual evapotranspiration for effective crop management. Actual evapotranspiration indicates the actual amount of water evaporated through the surface while potential evapotranspiration is the ability of the atmosphere to remove water from the surface by evaporation and transpiration. Potential evapotranspiration takes a higher value than the actual evapotranspiration. Hence, crop water need can be calculated by subtracting the actual evapotranspiration from the potential evapotranspiration.

什么是实际的蒸发?
实际的蒸散量是通过蒸发和蒸腾过程从表面去除的水数量。因此,它解释了土壤,土地表面和大气之间的水和能量的交换。实际的蒸散量很难衡量。但这是自然生态系统中极为重要的过程。此外,它是水周期的主要组成部分,因为它会影响水平。
What is Potential Evapotranspiration?
潜在的蒸散量是通过蒸发和蒸腾作用大气从表面去除水的能力的量度。在测量潜在的蒸散液时,假定供水没有控制。

实际上,潜在的蒸散剂是对蒸散大气需求的代表,这是蒸发和蒸腾的总和。这个过程需要能量。主要能量来源是阳光和风。潜在的蒸散量利用了其80%的能量从太阳中使用。其次,该过程从风中吸收能量。
What are the Similarities Between Actual Evapotranspiration and Potential Evapotranspiration?
- Actual and potential evapotranspiration are two types of evapotranspiration processes.
- 科学家认为这两个过程是出于水资源管理的实际目的。
- 这crop water need can be calculated by subtracting actual evapotranspiration from the potential evapotranspiration.
- 当有大量的水时,据信实际的蒸散量是等于潜在的蒸散剂。
- 这两个过程对于地球上的水平衡都很重要。
- Sunlight and wind play major roles in both processes.
实际的蒸散液和潜在的蒸散量有什么区别?
实际的蒸散量是通过蒸发和蒸腾实际上从表面去除的水量。相比之下,潜在的蒸散量是对大气在有充足水的情况下通过蒸散从表面去除水的能力的量度。因此,这是实际蒸散量和潜在蒸散量之间的关键区别。
此外,潜在的蒸散量通常比实际的蒸散量更高。但是,当有大量的水时,据信实际的蒸散量是等于潜在的蒸散剂。
Below is a summary of the difference between actual evapotranspiration and potential evapotranspiration.
Summary – Actual Evapotranspiration vs Potential Evapotranspiration
蒸散是通过蒸发和植物蒸腾作用从地球的土地和海面转移到大气中的。实际蒸散量是通过蒸发和蒸腾去除的实际水量。相比之下,潜在的蒸散量是在没有水的控制时通过蒸发和蒸腾来清除水从表面上去除水的能力的量度。当有充足的水时,实际蒸散液被认为等于潜在的蒸散量。因此,这是实际蒸散和潜在蒸散量之间的差异的摘要。
