碩士 === 國立雲林科技大學 === 環境與安全工程系碩士班 === 91 === Biogenic VOCs play a direct role in atmospheric photochemical cycle, and form a portion of the global carbon cycle. There are many kinds of trees in Taiwan, and the effect of biogenic VOCs emissions in Taiwan make people to respect and research. Base on BEIS-2（Biogenic Emissions Inventory System Version 2）and match up the land use database and meterological data of Taiwan to develop TBEIS（Taiwan Biogenic Emissions Inventory System）. It’s result need to be as the basis to improve the model accuracy. The purpose of this study are using Tethered balloon method to measure the emissions of biogenic volatile organic compound and the results will compare with the modeling results of Taiwan Biogenic Emission Inventory System Version 2.2（TBEIS 2.2）. Further to know the vertical distribution characters of biogenic volatile organic compound emissions for Taiwan and the effect for ozone. The results shown that biogenic VOCs concentration vertical profile main effected by wind direction. Each profile shown biogenic VOCs concentration variously. Ozone peak generated by photochemical reaction and offshore transmission. In Chiao-Kuang elementary school, most of Isoprene emission flux modeling value greater than estimated value. On the contrary, most of Monoterpene emission flux estimated value greater than simulated value. In HuiSun forest, estimated values are greater 3 ~ 4 times than simulated values. Using the simplified emission flux formula to estimate will lead to the error of Isoprene emission flux is approximately –41% ~ 72.9%, and the error of Monoterpene emission flux is approximately –37.7% ~ 48%.
