摘要

蒸散发是计算地表能量平衡、wáter平衡和作物水分胁迫和作物产量决定的关键因素。然而，它的直接测量或估计往往是复杂的，因为在这个物理过程中起作用的因素的多样性和复杂性。(形态、生理和土壤因素)。SEBAL(陆地表面能量平衡算法)基于卫星图像估算ET，利用表面能量平衡原理，不同科学家作者的几项研究报告得出了极好的结果;最大限度地减少对大植被带的ET测定的成本和时间。本研究工作的目的是利用2016年作物周期内的Landsat 8卫星图像，通过SEBAL估计位于墨西哥杜兰戈市Gomez Palacio的一个商业农场的石榴作物的潜在蒸散发量。结果与FAO 56方法估算的ET进行了验证，得到了0.96的Willmott一致性指数，表明估算精度较高。

Evapotranspiración del cultivo de granado por balance de energía

Evapotranspiration is a key element in calculating the surface energy balance, wáter balance and crop water stress and crop yield determination. However, it´s direct measurement or estimation is frequently complicated, since the diversity and complexity of the factors acting in this physical process. (morphological, physiological and soil factors). SEBAL (Surface Energy Balance Algorithm for Land) estimates ET based on satellite images, using the principles of surface energy balance producing excellent results as reported in several studies of different scientist authors; minimizing the cost and time for the ET determination for large vegetation zones. The objective of this research work was to estimate the potential evapotranspiration for the pomegranate crop in a commercial farm, located in Gomez Palacio, Durango, Mexico, by SEBAL using Landsat 8 satellite images during the crop cycle 2016. The results were validated with estimates of ET by the FAO 56 method, obtaining a Willmott concordance index of 0.96, which means good estimation precision.

期刊介绍： The Journal of Symbolic Logic publishes research in mathematical logic and its applications of the highest quality. Papers are expected to exhibit innovation and not merely be minor variations on established work. They should also be of interest to a broad audience. JSL has been, since its establishment in 1936, the leading journal in the world devoted to mathematical logic. Its prestige derives from its longevity and from the standard of submissions -- which, combined with the standards of reviewing, all contribute to the fact that it receives more citations than any other journal in logic.
