Abstract
Forest resources are crucial for maintaining global ecological balance and biodiversity.As human activities and climate change intensify,accurately understanding the status of forest resources becomes increasingly important.To accurately understand the status of forest resources,the drone LiDAR technology is utilized in this paper for detailed investigation and long-term monitoring of coniferous forests in northeast China.By using multi-rotor drones and high-precision LiDAR sensors,the high-precision 3D point cloud data was obtained to extract forest structure parameters and establish biomass estimation models.The results indicate that the drone LiDAR technology is high efficient,accurate,and reliable and can provide new technical means for forest resource management.Long-term monitoring data shows an increasing trend in tree height,canopy density and biomass,meanwhile demonstrates the significant application value of this technology in forest resource investigation and monitoring.
