利用北京市蒙古栎定期清查数据，在Richards模型中引入哑变量，将间伐林分和未间伐林分合并建立林分断面积、蓄积量生长模型。结果表明：含有哑变量的林分断面积、蓄积量生长模型，对蒙古栎林分的断面积、蓄积量的模拟效果都较好，R2分别达到了0．982、0．993。通过对模型的独立性检验，拟合模型对林分断面积、蓄积量的预测精度均在95％以上，可以用来描述北京地区蒙古栎间伐林分和未间伐林分的生长变化规律，也解决了不同类型林分合并建模不相容的问题。

With the periodic inventory data of Quercus mongolica in Beijing, we tookthinned and unthinned stands together to establish unified stand basal area and volume growth models by Richards model with the dummy variables .The stand basal area and volume growth models for Q.mongolica with dummy variables are with better simulation, and R2 are 0.982 and 0.993, respectively.By independence test, the forecasting precisions of fitting models in stand basal area and volume are over 95%.The models can be used to describe the growth rule of thinned and unthinned stands of Q.mongolica in Bei-jing, and can be compatible with unified modeling for different types stands.
