【摘要】 植物蒸腾作为水循环中的重要环节,是分析陆面生态过程与气候相互作用、预测生态环境变化的重要手段,也是计算植物生态需水量的依据。蒸腾测量方法研究是进一步认识水循环的基础,对其精确的测量可以提高水文模型的精度。文章主要从3个阶段对蒸腾的主要测量方法及优缺点进行了综述,旨在为选择合适的蒸腾测量方法提供科学依据。更多还原

【Abstract】 As an important link in the water cycle, the plant transpiration is the tool to analyze the interaction between terrestrial ecological processes and climate and to predict the variation of ecological environment, also is the basis for calculation of ecological water demand of plants. The study of measurement of transpiration is the basis of further understanding of hydrological cycle. The precise measurement of transpiration will increase the accuracy of hydrological models. The main methods for transpiration measurement in three steps and their advantages and disadvantages are reviewed aiming at providing a basis for choosing proper method of transpiration measurement.更多还原
