广东省湛江市岭头岛红树林保护小区野外样地2023年6月调查数据集

在无人机数据采集的同时，同步进行了的野外调查。在研究区内划分了5个调查区域，考虑到红树林的类型分布和生长状况，在每个调查区域的不同方位选取了红树林样木。记录了红树林的类型、地径、树高和冠幅信息。使用皮尺测量了样木的东西和南北冠幅，并计算了两个主要方向上的冠幅平均值，以此作为平均冠幅。同时，通过RTK定位系统获取了单木的位置信息，定位精度达到5厘米。调查中记录的树高范围是0.6至6.5米，冠幅范围是0.4至6.1米。

Field investigations were conducted synchronously while collecting unmanned aerial vehicle (UAV) data. Five survey areas were delineated within the study area. Considering the type distribution and growth status of mangroves, mangrove sample trees were selected at different orientations within each survey area. Information including mangrove type, ground diameter, tree height, and crown width was recorded. The east-west and north-south crown widths of the sample trees were measured with a tape measure, and the average value of the crown widths in these two main directions was calculated as the average crown width. Meanwhile, the position information of individual trees was obtained via the RTK positioning system, with a positioning accuracy of 5 centimeters. The recorded tree heights in the investigation ranged from 0.6 to 6.5 meters, while the crown widths ranged from 0.4 to 6.1 meters.
