基于无人机激光雷达数据的杉木人工林碳储量估测方法研究
Estimation of forest carbon storage in Chinese fir plantation by UAV-Lidar
[目的]森林碳储量是衡量森林生态系统基本特征的重要指标,传统碳储量估测方式需要耗费大量的时间、人力、物力等,本研究利用无人机搭载激光雷达获取机载激光数据并建立森林碳储量估测模型,为获取区域内森林碳储量提供参考,从而更好地对森林资源进行监测。[方法]本研究以杉木人工林为研究对象,利用机载激光雷达点云数据获取点云特征变量,以此作为建模变量进行模型研建。通过不同筛选变量方式选择建模变量,分别建立非线性回归模型、线性回归模型和随机森林模型并进行模型评价,…查看全部>>
[Objective]Forest carbon storage is an important index to measure the basic characteristics of forest ecosystem.Traditional carbon storage estimation method requires a lot of time,manpower and material resources.In this study,unmanned aerial vehicle equipped with Lidar was used to acquire airborne laser data and establish a forest carbon storage estimation model to provide reference for obtaining forest carbon storage within the region,so as to better monito…查看全部>>
