In order to obtain a high-precision estimation of stand volume conveniently and quickly in forest resources investigation,based on the data of 96 plots of Chinese fir stand in west Dongting lake region,the relative tree height curve model for the region was built.The experimental results with hypothesis testing（t-test） show that the accuracy of volume estimate of the model was relatively ideal,and the accuracy was almost as high as that by using tree height curve.The obvious deviation caused by form height variation was avoided when estimatin...
