日光温室环境预测模型构建

在借鉴国内外温室环境模型成果的基础上，利用热平衡原理建立了日光温室环境预测模型，该模型综合考虑了自然通风、作物蒸腾、地面蒸发、土壤传热和后墙传热对日光温室室内温湿度的影响，利用室内外的环境参数、室内作物的生长状态和自然通风口开口大小等参数，可以预测日光温室内部温湿度的变化情况，对日光温室环境调控具有一定的指导意义。

Forecasting Environment Model of Sunlight Greenhouse Based on Thermal Balance

In this paper, a forecasting environment model of sunlight greenhouse was developed using thermal balance, based on thermal environmental models developed by internal and external researchers. The physical processes such as evapotranspiration of the plant and the ground, heat transfer of soil and the back wall of the sunlight greenhouse, natural ventilation, etc. were synthetically considered in the model. By using this model, environmental parameter changes of a period of time inside the greenhouse can be predicted by inputting the present environmental conditions inside and outside the greenhouse, the indoor crop growth state and the size of natural vent. Initial validation and calibration had shown that the prediction of the model coincides with the measurement.
