摘　　要：针对温室小气候的基本特点,结合国际较新的热平衡稳定状态方法,根据西北地区夏季的温室具体情况,建立了温室的温度、湿度模型。通过对模型的分析和仿真试验,取得了较好的效果。The microclimate of greenhouse was a nonstationary,nonliner dynamic environment with strong coupling and great lag.The model and emulation were established for the greenhouse microclimate in order to build a sound supervisory and control system of the greenhouse.Based on the characteristics of microclimate of greenhouse,and the specific macroclimate in the summer of northwest china,the temperature and humidity models were set up by the new international method of heat banlance steady state equation.Through the analysis and emulation experiments,the effects were basically conform what were supposed.
