摘　　要：光伏铺设方式会引起日光温室内温湿度等环境因素的变化,进而影响作物的生长。搭建光伏日光温室温湿度模型,以模拟不同光伏铺设方式下日光温室内温湿度的动态变化。采用上半铺、棋盘铺、全铺等三种铺设方式将光伏组件安装在日光温室南坡,采用能量平衡和质量平衡原理建立温湿度数学模型,使用Matlab/Simulink构建温湿度逐时动态仿真模型,采用实测数据对仿真模型进行验证,并分析讨论了光伏铺设方式对室内温湿度的影响。冬至日温室四个区域温湿度仿真的MAPE最大值为1.297%、平均值为1.16%,RMSE最大值分别为0.618℃、1.75%;30日温湿度MAPE最大值为1.176%、平均值为0.92%,30日温室四个区域温湿度仿真的RMSE最大值分别为0.171℃、1.882%。结果表明,构建的温湿度逐时动态仿真模型可较为全面、精确地反映光伏不同铺设方式下的日光温室内环境。光伏铺设面积越大温室内温度越低,光伏铺设对温室内相对湿度影响并不明显。三种光伏铺设方式中,上半铺方式可获得更高的温室内平均温度。研究可为温室内温湿度环境调控、光伏铺设方式选择和温室设计建造提供理论指导。The photovoltaic laying method-can will can cause changes in environmental factors,such as temperature and humidity in the photovoltaic Chinese-style solar greenhouse,which in turn affects crop growth.A photovoltaic Chinese-style solar greenhouse temperature and humidity model was built to simulate the dynamic changes of temperature and humidity in the photovoltaic Chinese-style solar greenhouse under different photovoltaic laying modes.The photovoltaic modules were installed on the Chinese-style solar greenhouse's south slope using upper-half paving,checkerboard paving,and full paving.The mathematical model of temperature and humidity was established by adopting the principles of energy balance and mass balance.Matlab/Simulink constructed the time-by-hour dynamic simulation model of temperature and humidity and measured data to verify the simulation model.The influence of the photovoltaic laying method on indoor temperature and humidity is analyzed and discussed.The maximum value of MAPE and the average value of temperature and humidity simulation in four regions of the greenhouse on the winter solstice were 1.297%and 1.16%,and the maximum value of RMSE was 0.618℃and 1.75%,respectively.The maximum value of MAPE for 30-day temperature and humidity was 1.176%,and the average value was 0.92%.The maximum value of RMSE for 30-day temperature and humidity simulation in four greenhouse regions was 0.171℃and 1.882%,respectively.The results showed that the time-by-hour dynamic simulation model of temperature and humidity can comprehensively and accurately reflect the internal environment of a photovoltaic Chinese-style solar greenhouse under different photovoltaic laying methods.When the temperature inside the greenhouse was lower,a larger photovoltaic laying area showed no significant effect on the relative humidity inside the greenhouse.Among the three photovoltaic laying methods,the upper half laying method obtained a higher average temperature inside the greenhouse.The research can provide theoretical guidance fo
