对水源管理者来说,只有在水通过物理蒸发变成空气的一部分,或者被植物吸收并且转变为水蒸气形式(蒸腾作用)的时候,才被消耗了。
For a water manager, the only time water is consumed is when it evaporates into the air or is soaked up by plants and then turned into water vapor (transpiration).

This can help not only balance the carbon budget, but also predict evaporation rates and other weather and climate-related matters that are heavily reliant on plants.
二氧化碳是一种温室气体,所以会引起地球变暖,但同时二氧化碳也会引发植物的蒸发冷却作用。
Carbon dioxide warms the Earth because it is a greenhouse gas in the atmosphere, but it also causes plants to provide less evaporative cooling.
植物通过其叶子上的微细小孔排出水分,这个蒸发过程使植物降温,就好像流汗使我们凉快一样。
Plants give off water through tiny pores in their leaves, a process called evapotranspiration that cools the plant, just as perspiration cools our bodies.

虽然海洋蒸发的水蒸气是水循环中地球表面到大气这一渠道的首要组成部分,植物蒸腾所占的部分也颇为惊人。
While evaporation from the oceans is the primary vehicle for driving the surface-to-atmosphere portion of the hydrologic cycle, transpiration is also significant.
“有97%或98%从安哥拉流入的水分,都通过植物、树木等蒸发进入了空气,这是非常独特的,”他说。
"About 97 or 98% of the water that flows in from Angola goes into the air through the plants and through the trees and in this, it's pretty unique," he continued.
在缺乏水分时,植物一般用蒸发作为降温的手段。
When it is short of water, a plant normally USES evaporation as a means of cooling.
实际的需水量根据植物种类,气候(植物吸收的大部分水用于进行蒸发降温),和灌溉效率的不同而有所不同。
The actual water requirements differ according to plant, climate (most of the water withdrawn by plants is for cooling through evaporation) and the efficiency of irrigation.
在这种前提下,测量水的消耗(使用)量,即是测量物理蒸发和植物蒸腾作用的总量。
Under this definition, measuring water use comes down to measuring evaporation and transpiration, or.
在缺乏水分时,(植物)一般用蒸发作为降温的手段。一株植物无法消除它从阳光中所吸收的热量,或是无法消除它在新陈代谢过程中积累起来的热量。
When it is short of water, a plant, which normally USES evaporation as a means of cooling, cannot rid itself of the heat it absorbs from sunlight or the heat that may build up from its own metabolism.
城市街道上,房顶上的绿色植物更多了,这意味着随着水分从叶片上蒸发,会带来更多的清凉;非绿色部分可以涂成白色用以反射太阳光。
More greenery in a city, spread through streets and over roofs, means more cooling as water evaporates from leaves; the bits which are not green can be painted white, to reflect sunlight.
植物通过水分蒸发调节绿色屋顶的温度。
Plants in green roofs regulate their temperatures through evapotranspiration.
但在同一区域,例如北美的一些地区和东亚,植物的蒸发作用能引起超过25%的全球暖化。
But in some regions, such as parts of North America and eastern Asia, it can be more than 25% of the total warming.
更多的水则是从植物的叶子上蒸发。
高温也导致了植物水分的大量蒸发。
High temperatures also result in high evaporation from the plants.
这些植物进行蒸发,释放出更多的水蒸气。
该模型用于模拟发生严重荒漠化的鄂尔多斯高原植物群落的季节及年生长、叶片投影盖度、蒸发系数。
The model was developed to simulate seasonal and annual growth, foliage projective cover (FPC), and evaporative coefficient in the Ordos plateau, where serious desertification happened recently.
这是因为温度升高会增加水的消耗和蒸发,植物的蒸腾也会加快。
This is because the higher temperatures will increase water consumption, evaporation and plant transpiration rates.
从日变化数据来看,植物蒸腾由于能消耗更深层次的水分,其强度的减弱要迟于土壤蒸发。
The data of daily-variety indicates the lowering of intension of plant transpiration is later than evaporation of soil surface, because transpiration can consume the deeper layer water.
土壤水分通过植物根系和土面蒸发进入大气从而使三者成为一连续统。
Soil water is the link of the continuum, which makes soil system, plant system and atmosphere system become a continuum by water absorption of root system and water evaporation of soil surface.
研究结果表明:高聚物不仅能提高土壤的持水力和增加土壤水对植物的有效性,而且还能抑制土壤水的蒸发。
The result shows that the high polymers VAM and PHM can not only enhance the water retention ability and the available water content, but also prevent the evaporation from the surface soil.
包括土壤蒸发和植物蒸腾两部分。
他知道这里年降水量才几十毫米,蒸发量却达到近一千毫米,炎热干旱主宰着一切,每棵植物为生存不得不都畸形发展。
He knew every mound, every plant and that everything was governed by heat and drought, evaporation being twenty times precipitation.
他知道这里年降水量才几十毫米,蒸发量却达到近一千毫米,炎热干旱主宰着一切,每棵植物为生存不得不都畸形发展。
He knew every mound, every plant and that everything was governed by heat and drought, evaporation being twenty times precipitation.
