摘　　要：准确了解蒸散发对获取植物生理生态参数非常重要,但目前的蒸散发测量方法依赖于侵入式、固定式的仪器设备,尚缺乏较为方便的移动测量方法。本研究提出一种依赖于移动端设备,获取红外成像技术图片测量得到植物叶温值,随后根据"三温模型"原理测定得到植物蒸腾速率的方法。通过室内盆栽试验数据,研究结果基本验证了技术流程的可行性,且结果之间互为验证,说明该方法具有较好的应用前景。若开后期展大规模的应用和比较,可能获得较好的推广价值。本研究也可作为其他研究的理论参考和技术依据。It is very important to accurately understand evapotranspiration for obtaining plant physiological and ecological parameters.But the current methods of evapotranspiration measurement rely on invasive and fixed instruments and equipment,and there is still a lack of more convenient mobile measurement methods.In this study,a mobile device was used to measure the leaf temperature of plants by acquiring infrared image technology,and then the transpiration rate of plants was measured according to the principle of"three temperature model".Through the indoor pot experiment data,the research results basically verified the feasibility of the process of the technology,and the mutual results verified each other,which showed that the method had a good application prospect.If large-scale application and comparison were carried out in the later stage,it was possible to obtain better promotion value.This study can also be used as a theoretical reference and technical basis for other studies.
