无人机低空遥感技术辅助高精度造林

在高精度要求的造林作业中，使用传统的造林方法进行造林作业会伴随着精度不足、效率不 高、人力耗费大等问题。研究利用无人机航拍获得造林地的正射影像图，使用 AutoCAD 和 ArcGIS 软件 设计种植方案，按照设计方案施工完成后，验证相对误差是否符合作业的精度要求。结果表明：（1）试 验产生的相对误差极显著小于允许误差（P <0.01)；（2）将劳动力和时间的成本量化为工作时后进行比 较，试验中实际工作时约为 10 h, 远小于传统作业标准中所规定的工作时 116 h。相较于传统造林方法， 该方法不仅精度更高，而且可以节约大量的劳动力和时间，该方法具备可行性和实用性，在具备设备条 件与技术条件时，可以使用该方法进行高精度造林作业。

High-precision Afforestation Assisted by UAV Low-altitude Remote Sensing Technology

In high precision afforestation work, the traditional design method has many problems, such as low precision, low efficiency and large labor cost. This experiment attempted to solve these problems in high precision afforestation, which was assisted by UAV low-altitude remote sensing technology. First of all, orthophoto map of forestland was photographed by drone, then planting scheme was designed with AutoCAD and ArcGIS software. After the plantation work finished, the relative error was assessed. In the end, the feasibility and practicability of the method was discussed. The results show that: (1)The relative error was significantly lower than the permissible error(P<0.01); (2)The actual labor and time consumed in the experiment is about 10 h, which is far less than the labor and time specified in the operating standard of 116 h. Compared with the traditional method, this method is not only more accurate, but also can save labor cost and time. Therefore, it is a feasible and practical method and worth popularizing.
