摘要: 对目前国内外森林蒸散研究中的主要理论和方法(蒸渗仪法、风调室法、涡动相关法、水量平衡法、能量平衡法、波文比法、彭曼联合法、SPAC法、经验公式法和应用遥感数据的方法)进行了总结,探讨了其实际应用中所存在的问题简单介绍了应用闪烁计数器直接观测显热通量以及应用双频微波辐射计探测大气水汽、云中液态水含量的技术.提出通过对大气水汽平衡的研究来推求蒸散量的设想,预测了森林蒸散研究的发展趋势.

Abstract: The authors summarized the main theories and methods in the research of forest evapotranspiration,which are lysimeter,ventilated chamber,eddy correlation,water balance,energy balance,EBBR,Penman-Monteith,SPAC,experience formula and remote sensing methods,and the problems in applications were discussed.The use of scintillometer to measure sensible heat flux and the use of double frequency macrowave radiometer to gain the capacity of atmospheric water vapor and cloud liquid water were introduced.Finally,the idea to acquire the quantity of evapotranspiration by the analysis of atmospheric water vapor balance was proposed,and the future trends in forest evapotranspiration research were forecasted.
