利用秃杉人工林标准地调查数据，以理查德为基本方程，采用哑变量的方法，引入立地质量因子，构建以立地质量为哑变量的秃杉人工林树高曲线模型，并将其与二元材积表相结合，测算标准地蓄积量。经交叉建模检验，建立的树高曲线模型，其估算精度接近二元材积表的估计水平。所构建的树高曲线模型在很大程度上减少了野外调查的工作量，提高了工作效率，为中国的森林资源调查提供一定的参考应用价值。
利用禿杉人工林標準地調查數據，以理查德為基本方程，採用啞變量的方法，引入立地質量因子，構建以立地質量為啞變量的禿杉人工林樹高麯線模型，併將其與二元材積錶相結閤，測算標準地蓄積量。經交扠建模檢驗，建立的樹高麯線模型，其估算精度接近二元材積錶的估計水平。所構建的樹高麯線模型在很大程度上減少瞭野外調查的工作量，提高瞭工作效率，為中國的森林資源調查提供一定的參攷應用價值。

Based on the sample-plot survey data in artificial forest of Taiwania cryptomerioides, Richards equation was used as the basic equation , and method of dummy variable of site quality factor was introduced .Tree height curve model of artificial forest of T.cryptomerioides with the dummy variable of site quality was built and combined with the binary volume table to calculate standard volume.After cross modeling examination , the estimated accuracy of the established tree high curve model was close to the binary volume table.The work of the field survey would be largely reduced and more efficient , it could be some of reference and application value to forest resources survey in our country .
