chinois. 为了提高温室生产性能和生产效益，以温室主栽品种之一的番茄为对象，单叶光合作用模型为基础，综合考虑叶面积动态指数、温室冠丛光分布构建了群体光合作用模型，分析了温室内温度、CO2浓度及水分对模型的影响，并据此对模型进行修正。对模型进行验证，结果表明，该模型的群体光合速率实测值（0值时除外）与模拟值的相对误差在0～10.0%之间，模拟精度较高，环境因子对番茄生长发育影响的预测效果良好。

In order to improve the productivity and the production efficiency of the greenhouse, the canopy photosynthesis model of tomato, one of the main species cultivated in greenhouse was developed based on simple leaf photosynthesis, the comprehensive consideration of leaf area index and the light density distribution in greenhouse. The model was adjusted according to the influence of the environment factors (temperature, CO2 concentration and moisture). The results of model validation showed that the relative error of photosynthetic rate between observed (except for 0) and simulated value is among 0 and 10.0% and good consistency was observed. The model developed in this study could predict the variation of photosynthetic rate successfully.
