Ｗｅｉｂｕｌ分布拟合实际的林分直径分布，效果良好。在Ｗｅｉｂｕｌ三参数及林分因子的基础上，建立了参数预测模型和参数回收模型。经误差检验，参数回收模型优于参数预测模型。
The Weibul distribution fits the actual stand diameter distribution and works well. Based on Weibul three parameters and stand factors, a parameter prediction model and parameter recovery model were established. After error checking, the parameter recovery model is superior to the parameter prediction model.
