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. In order 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 guided hyperspectral images to investigate the spatial and temporal dynamics of these systems for the next five 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 landscape scale seasonal airborne remotely sensed biophysical observations at a sub-meter ground sampling distance. Developing a network of environmental observation systems is cutting edge of current science. For instance, the National Science Foundation USA just launches NEON (the National Ecological Observatory Network) this year (2011), the largest ecological observation program ever in the human history for the next three decades. EcoNTU will collect similar data like NEON but with much lower budgets. This makes EcoNTU even more valuable for environmental science communities of the world, especially those of the developing/undeveloped countries in the tropical regions managing invaluable natural heritages. High quality data collect by EcoNTU can be integrated in a systematic fashion. This would significantly facilitate cross-scale research and permit deciphering of ecosystem complexity of Taiwan’s terrestrial ecosystems that are extremely sensitive to climate change.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】
