报告人简介：Ran Wang got his PhD from the University of Alberta. He conducts research on monitoring plantbiodiversity and photosynthesis characteristics using multiscale remote sensing, ranging from proximal,airborne and satellite. He is currently working at the airborne research program (Nebraska EarthObservatory, NEO) at the University of Nebraska-Lincoln to explore the applications of airborneimaging spectrometry and solar induced fluorescence in assessing plant diversity, vegetation health andecosystem function.
报告内容：Biodiversity is essential to healthy ecosystem function, influencing ecosystem productivity, stability, and nutrient cycling. Biodiversity loss endangers essential ecosystem services and risks unacceptable environmental consequences. Global biodiversity observations are needed to provide a better understanding of the distribution of biodiversity, to better identify high priority areas for conservation and to help maintain essential ecosystem goods and services. Traditional in situ biodiversity sampling is often limited in time and space and is usually a costly and time-consuming enterprise. Remote sensing offers the potential to observe biodiversity at multiple temporal and spatial scales and has been used to detect plant biodiversity in a range of ecosystems, typically based on relating spectral properties to the distribution of habitat, species or functional groups. Recent years have witnessed the emergence of methods using imaging spectroscopy, which is identified as the ‘only technology’ that can provide detailed spectral information to identify and quantify plant biochemical and structural traits, to assess biodiversity via plant traits or spectral information content. However, questions regarding the complex drivers of plant optical properties and the scale dependence of spectral diversity – biodiversity relationship confound diversity monitoring using remote sensing and must first be better understood before these methods can be operationally applied.
