在水的运动中,蒸散作为一种水文过程,其地位仅次于降水。所以为了加深对这种过程的了解,提高其可预报性,一以促进农业水文学的发展,迫切需要进行蒸散研究。除了水文学通常对限制水的有效利用方面有附加的影响外,蒸散物理学实质上跟其他任何蒸发情况是一样的。水文方面的蒸散不仅对于水文预报很重要,而且对于地面上作物、草原和森林的生产也很重要。未来水文方面蒸散研究需要重视的几个重点方面是:扩大数据的可用程度;改进分析和综合方法;更好地确定对土壤水蒸散的影响和随时间及空间而变化的植被蒸散的影响。必须发展、试验标准化的方法,推广传统应用方法以外的方法,宣传跟其他水文技术的结合。
In water movement, evapotranspiration is a hydrological process, second only to precipitation. Therefore, in order to deepen the understanding of this process and improve its predictability, it is urgently necessary to study evapotranspiration in order to promote the development of agricultural hydrology. Transpiration physics is essentially the same as any other evaporation except that hydrology usually has an additional impact on limiting the effective use of water. Hydrological evapotranspiration is not only important for hydrological forecasting but also important for the production of crops, grasslands and forests on the ground. In the future, several important aspects of evapotranspiration research in hydrology are: increasing the availability of data; improving analytical and integrated approaches; and better determining the impact on soil water evaporation and the impact of vegetation evapotranspiration over time and space. It is imperative to develop and test standardized methods, to promote methods other than traditional methods of application, and to promote the integration with other hydrological techniques.
