It would induce tremendous impacts on terrestrial environments regionally and globally, and trigger collateral damages on the society and economy. The ramifications are difficult to assess without frequent ecosystem observations at the regional scale. Therefore, this research is designed to monitor the “vital signs” of Taiwan’s natural terrestrial environment: biogeochemical, hydrological and energy cycles. To do that, we will set up a network of research sites that are representative to Taiwan’s main ecosystems, namely EcoNTU (Ecosystem Complexity Observatories for a Network of Terrestrial Units). In this project, we propose an innovative approach that utilizes synoptic sensing techniques to integrate different scales of field observations, and unmanned aerial vehicle (UAV) guided hyperspectral images to investigate the spatial and temporal dynamics of these systems for the coming years. The primary objective is to establish a prototype of environmental observation network that can rapidly and accurately assess the conditions of ecosystems in great detail over a vast region in the era of global change. EcoNTU combines multi-scale observations including local scale, frequent measurements of eddy covariance flux, meteorological information, stream flow, biogeochemistry; and cross-scale seasonal remotely sensed biophysical observations at a sub-meter ground sampling distance. The first year’s research focus was on the enhancement of data acquisition systematicity. In the following year, we will start synthesizing these data to estimate the export of nitrogen from watersheds, spectroscopically assessing the quality of mountain oolong tea and mapping the invasion of alien plants using narrow-band UAV images.生物地球化學渦流相關法通量塔高光譜遙測氮色素無人航空載具分水嶺biogeochemistryeddy-covariance methodflux towerhyperspectral remote sensingnitrogenpigmentunmanned aerial vehiclewatershed前瞻研究領航計畫【建立跨尺度臺灣陸域生態系統監測網】
