摘要: 本文简述了林木蒸腾耗水的概念、研究价值和研究进展,从实测法和估测法的角度,综述了林木蒸腾耗水量的主要测算方法,对比了各方法的优缺点、适用性、局限性、应用现状以及适用尺度。本研究认为: 实测法可应用于多种空间尺度耗水量的测定,估测法常应用于大空间尺度蒸散量的测算。实测法是估测法的基础,因此应对实测法的测定结果进行合理的质量控制与评价,为校正估测法的估算结果提供数据基础。不管是同一大空间尺度还是不同空间尺度,实测法和估测法的结合能够提高蒸散量测算结果的准确性。提升复杂下垫面和恶劣气候环境下大空间尺度林木蒸散量的测算精度将成为未来的研究热点与难点。随着科学技术的不断进步,现有的测定装置和测算方法将被改进,精确测定林木蒸腾耗水量的新方法也将随之诞生。

Abstract: In this study, the concept, research value, and research advances of tree transpiration were concisely narrated. From the perspective of measurement and estimation, we summarized the main calculation methods for water consumption of tree transpiration. By comparing the advantages, disadvantages, applicability, limitations, application status, and applicable scale of different methods, we showed that the measurement methods could be applied to the measurement of water consumption at multiple spatial scales, and that the estimation methods were often applied to the measurement of evapotranspiration at large spatial scales. As the measurement method was the basis of the estimation method, it is necessary to carry out reasonable quality control and evaluation of the measured results of measurement methods, in order to provide data basis for the estimation results of the correction estimation method. Whether it was at a particular large spatial scale or at different spatial scales, the combination of measurement methods and estimation methods could improve the accuracy of evapotranspiration measurement. Improving the accuracy of calculating the dispersion of trees at a large spatial scale in complex underlying surface and harsh climate environments would become a research hotspot but may also be a difficulty in the future. With the continuous progress of science and technology, both measurement devices and methods would be improved, and new methods for accurately measuring the water consumption of forest transpiration would be available.
