针对育秧大棚内部空气流动对水稻秧苗生长环境的影响问题，分析了水稻育秧大棚内部环境分布情况。同时，利用Gambit 对大棚进行三维建模、Fluent 求解计算、CFD－post 后处理分析，并运用k－ε湍流模型、太阳辐射追踪器、组分模型来计算模拟大棚内部温湿度场及气流速度场分布。结果表明：温湿度模拟值与测量值吻合较好，相对误差均控制在5％以内。本模型可以为其他气候和边界条件下的大棚环境预测、结构参数优化提供参考及理论依据。

The study analysis the distribution of the internal environment of rice seedlings greenhouse for raising seedling shed internal air flow's influence on the rice seedlings growth environment problem.Use Gambit for greenhouses 3-d mod-eling, Fluent solving calculation, CFD -post post-processing analysis.Using the k -εturbulence model, the solar ray tracing, species model is used to calculate temperature and humidity and air velocity field distribution inside the green-house .The results show that the temperature and humidity accord well with those of simulated values and measured values , control the relative error within 5%.This model can be used for other climate and boundary conditions of greenhouse en-vironment prediction、offer reference and theoretical basis for optimization of structural parameters.
