摘要:
 热成像仪能够准确测定物体表面的温度,给农林植物科学研究带来了新的手段。针对热成像仪的特点,为了更好地应用于测定农林植物体温度,将热成像仪应用于荆条灌丛体温和栓皮栎幼苗叶温的测定。结果表明:1)农林植物体温的测量可以使用热成像仪,测定前要确定待测物体的辐射出射率。2)对于栓皮栎幼苗叶温,热成像仪与热电偶测定结果非常一致,说明热成像仪适于叶温测量。3)热成像仪可以测定植物群体冠层内和冠层表面叶片的温度,但不能测定空气温度。气温测量仍需要使用热电偶或热敏电阻等传感器。4)热成像仪可以分析荆条冠层的温度分布等值线,展示群体温度分布特征。既为荆条灌丛对栓皮栎幼苗的保育作用研究提供方法,也为热成像仪在其他农林植物体温测定研究中的应用提供参考。
Abstract:
 Thermal imager can measure surface temperature of matters accurately,it provides a new method for agricultural and forestry research.Temperatures of Vitex negundo var.heterophylla community and Quercus variablis seedling leaves were measured by thermal imager to provide examples of the application of thermal imaging technique in agriculture and forestry.The results showed 1) before applying thermal imager to measuring temperature of plants,the radiation emission rate of plant organs had to be determined.2) The result of the temperature measurement of Q.variablis by using thermal couple was quite similar to that by thermal imager,indicating that the later was suitable for measuring leaf temperature of plants.3) Thermal imager could be used to measure canopy temperature of plant community and leaf surface temperature of the canopy,but the air temperature of the canopy had to be measured by using thermal couple or thermistor temperature instruments.4) Thermal imager could be used to analyze the isotherm of V.negundo var.heterophylla community canopy,and to show its temperature distribution feature.The results would provide not only a method of studying nurse effects of V.negundo var.heterophylla canopy to Q.variablis seedlings,but also a method of measuring other agricultural and forestry plants.
