研究領域

• 土壤生物化學
• 土壤微生物學
• 湖泊代謝

研究方向

• 1.山區森林土壤微生物族群
  探討土壤微生物族群的重要意義，在於可藉此瞭解環境因子對於微生物多樣性組成的影響。森林經營管理常導致土壤性質和微生物族群的改變。透過 16S rRNA 基因庫，得以分析經森林經營管理後土壤細菌族群的差異。森林砍伐和樹種變更的干擾，影響天然林和受干擾林間的微生物族群組成，且增加土壤族群的多樣性。
• 2.森林土壤的腐植物質的特性
  使用13C-NMR技術，探討不同森林土壤的腐植酸特性，包括植被、坡面效應、海拔高度的影響效應等等。強酸性和高水分含量造成了檜木林土壤低度的腐植化程度。終年多濕的環境，也減低了坡度效應對於腐植化作用的影響。
• 3.湖泊代謝
  我們使用高頻即時監控湖水溶氧的技術，研究鴛鴦湖季節性變化及控制湖泊代謝的因子。湖泊初級生產力和生態系呼吸量皆以初夏和中秋達到最高，但台風和入冬之後迅速下降。生態系呼吸量對於外來干擾作用的忍受度，高於初級生產力，且在台風季節呈現激烈的日間變化。冬季的和台風季節所導致的水體混和作用，扮演著構成湖泊碳儲存和釋放的重要功能。
• 4.推動科普寫作
  藉由詩、散文、專欄報導等不同文體，推廣生態科普寫作，介紹生物多樣性的理念和價值。致力生態寫作的動機和過程請參閱「臺灣英文新聞」的相關報導。<https://www.taiwannews.com.tw/en/news/4178121>
