This study will lead us to understand the proper crown parameter for tree volume estimation. In addition, it might contribute to improve the accuracy of tree volume estimation based on airborne laser scanner（ALS）,which can only use crown parameters as the features to estimate the DBH and tree volume. Eight sample trees were cut dawn based on field survey and the tree volume of each trees was calculated by sectional measurement.
