日光温室气象环境综合研究(四)——日光温室地温场模拟初探

A Comprehensive Research on the Meteorological Environment in Sun-Light Greenhouse ( IV )——A Preliminary Study in Simulating the Soil Temperature Field of Greenhouse

摘要: 在前人研究基础上,用有限差分方法建立了一个非稳态二维地温场的数学模型。该模型为进一步分析日光温室内土壤温度热状况和进行综合评价、选用提高日光温室地温措施提供了手段和依据。

Abstract: An unsteady two-dimensional soil temperature field model is established using the limited difference method in this paper. The model is proved successful and provides a scientific base in further analysing soil temperature conditions and selecting the soil temperature raising method of greenhouse.
