依据田间实测资料，运用水流的电模拟原理，定量分析了坡地赤红壤—芒果—大气连续体水分运移过程中水分势能和水流阻力各分量的大小、变化规律及其相对重要性．结果表明，水流在该连续体中运移时，其能量主要消耗在由叶部到大气这一环节上，水分势能损失达１５．４４９１～５８．４０３６ＭＰａ，水分流经土壤到达叶部，水分热能降低０．２８１８～０．６９７９ＭＰａ；水流阻力主要分布于从叶气孔腔到大气的扩散过程，叶—气系统的水流阻力占该连续体水流总阻力的９５．６８％～９９．０３％，植株体的水流阻力占该连续体水流总阻力的０．９７％～４．３２％，而土壤阻力相对可忽略不计．
Based on the field data and the electric simulation principle of water flow, the size, variation and relative importance of the components of water potential and water flow resistance in rhizos soil-mangrove-atmosphere continuum were quantitatively analyzed. The results show that when the water flow in the continuum, the energy is mainly consumed in the link from the leaf to the atmosphere, the potential energy loss of 15.4491 ~ 58.4036MPa, water flows through the soil to reach the leaf, moisture heat The water flow resistance is mainly distributed in the diffusion process from the leaf stomatal cavity to the atmosphere, and the flow resistance of the leaf-gas system accounts for 95.68% -99.03% of the total flow resistance of the continuous body. The plant resistance The flow resistance of the body accounts for 0.97% ~ 4.32% of the total flow resistance of the continuous body, while the soil resistance is relatively negligible.
