2018版钱江源国家公园冠层复杂度指数数据库

利用2018年航飞获取的钱江源国家公园全域点云数据，通过滤波算法，把点云中的地面点分离出来，形成地面点和非地面点，通过计算非地面点高度变异系数，表征冠层结果复杂度，从而形成2018版钱江源国家公园冠层结构复杂度分布数据库。

Using the full-coverage point cloud data of Qianjiangyuan National Park collected via aerial surveys in 2018, ground points were separated from non-ground points in the point cloud using filtering algorithms, yielding two distinct point subsets. The height coefficient of variation of the non-ground points was then computed to characterize the complexity of the canopy structure, thereby establishing the 2018 version of the canopy structure complexity distribution database for Qianjiangyuan National Park.
