Methods of"Three-dimensional and Holographic"observation for forest ecosystems centered on"Multi-Tower"
The research on forest ecology should develop towards more macroscopic and more microscopic at spatio-temporal scales,which has challenged traditional approaches for ecological observation.With the development of information technology,shifts in the research paradigm are critically needed.Based on Ker Towers as a Corner-Stone Research Infrastructure Project in Qingyuan Forest CERN,National Observation and Research Station,we propose a framework of"space-air-tower-ground"for integrated observation and research with the tower(s)as the center.The framework includes four components:active/passive satellite-based remote sensing(space),near-ground remote sensing platform by unmanned aerial vehicle with LiDAR and multi/hyperspectral sensors(air),tower group or single tower(tower),and long-term forest plot arrays(ground).Along with information technology such as the Internet of Things,cloud computation and artificial intelligence,data acquisition,transmission,compu-tation,analyzation and display can be achieved to develop an information technology-based"three-dimensional and holographic"observation and research in forest ecology.This framework would promote knowledge innovation in for-est ecology,ecosystem ecology,and forest science,and provide insights toward the paradigm shifts in geography,remote sensing science,boundary layer meteorology,and other disciplines.
