摘　　要：确定设施作物蒸腾蒸发量(ET_(c))对于准确制定设施作物灌溉制度、提高设施农业用水效率及设施蔬菜的产量和品质具有重要的意义.对确定设施作物ET_(c)的直接和间接模型进行优缺点及适用性分析,比较了不同类型参考界面蒸腾蒸发(ET_(0))模型的优势与局限性,对比了直接估算温室作物ET_(c)机理模型的准确性,并对不同机理模型中关键参数(冠层阻力参数)的确定方法及主要影响因素进行综述与分析.已有研究主要针对特定气候区域、温室通风类型、作物种类及种植季节,对冠层阻力参数进行修正,并验证模型的准确性,对温室作物ET_(c)模型的普适性研究不够充分,确定的模型参数往往不适用于其他类型温室或作物种植季节.推荐今后重点研究方向:研究温室作物ET_(c)变化过程对气候因子分布特征及变化规律的响应机理;研究不同ET_(c)机理模型对气候类型、作物种类及种植季节的适应性,构建更具普适性的温室作物ET_(c)模型.Determination of greenhouse evapotranspiration(ET_(c))is important in making the accurate irrigation schedule,improving the agricultural water using efficiency,and increasing the yield and quality of the greenhouse vegetables.The advantage,disadvantages and applicability of the direct and indirect ET_(c) models,different reference evapotranspiration(ET_(0))models for greenhouse crops were analyzed,and the accuracy of the direct mechanism ET_(c) models was compared,the models for determination the key parameters(canopy resistance parameters)and its influence factors were summarized and analyzed.The previous studies have mainly corrected the canopy resistance parameters and verified the accuracy of the model for specific climatic regions,greenhouse ventilation types,crop types and planting seasons.The universality of the greenhouse crop ET_(c) model is not sufficient,and the determined model parameters are often not applicable to other types of greenhouse or crop planting seasons.However,the applicability of these ET_(c) models and parameters in different type of ventilated greenhouses and crop needs to be validated.Hence,it is recommended to focus on the following research on the response characteristics of the greenhouse ET_(c) to the climatic variations,the comprehensive analysis of the applicability of the different mechanism ET_(c) models to the climatic and crop types,and the construction of the much applicability and high accuracy ET_(c) models.
