摘要：In this paper, LiDAR was introduced in tree height and stand volume measure. By experiment, the average of trees' height was 8.68 meter measured by LIDAR, while the actual value was 8.67; the relative error between them was 0.913% which showed positive correlation. Then we fitted the relationship of tree height and stand volume with different coefficient methods. From quadratic polynomial to six polynomial fitting results, the correlation coefficient changed slightly from the polynomial index increased by four. At last, we can drew that estimating forest stand volume with LIDAR technology can save amount of field work time and improve the work efficiency. It meets the requirement of forestry survey measuring. The reasons for that there was error and exceed error by use of LiDAR for height measurement, were also discussed
