粗根(直径大于0.5厘米的根系)在森林生态系统中扮演着重要角色,具有支撑、固定树冠和为其运输水分、矿质营养等功能。另外,粗根也是储藏树冠固定碳的重要器官。研究森林中的粗根在地下的空间分布特征,对于深入了解森林生态系统结构和功能有重要意义。传统的挖掘法不仅费时费力、破坏采样地点, Rough roots (roots> 0.5 cm in diameter) play an important role in forest ecosystems, supporting, fixing canopies and transporting moisture and mineral nutrients. In addition, the coarse root is also a key organ for storing canopy carbon. Studying the spatial distribution features of coarse roots in forest is of great significance for understanding the structure and function of forest ecosystems. The traditional mining method not only time-consuming and laborious, destruction of sampling sites,
