集之土樣,除分析其理化性質及礦物組成外,同時依照國際腐 植質學會(International Humic Substances Society; IHSS)建議之方法萃取其腐 植質,然後純化之。 純化之腐植質則進行元素分析,可見光譜分析,紅外線光譜分析 ,傳立葉轉換紅外線光譜分析,電子自旋共振光譜方法,掃描式電子顯微鏡檢測,及 核磁共振. 譜分析。 研究結果顯示,平鎮系腐植質的E4/E6 值均分別大於圳寮系腐植質,因此對於一個發 育時間愈長的腐植質,可能因為分解或氧化,而使分子量變小,趨於. 犁作用有助於腐植質的環狀聚合。 此外平鎮系耕犁區和非耕犁區表土腐植質的E4/E 6 值之差分別較圳寮系腐植質者小,所以耕犁作用,對於較穩定之平鎮系腐植質之影 響不若對圳寮.

Humic substances, the remarkable brown biomaterials in animals, coals, plants, sediments, soils and waters, are crucial components of the carbon cycle and other life processes. Thus greater knowledge and understanding of these versatile materials is of great importance to the productivity, health and safety of the world's ecosystems, humans, land and water. Areas covered include spectroscopy, modelling, mobility, properties and analysis of humic substances.

"The characterization remains one of science's most intriguing challenges. It is clear from the collection of papers that humic substances make a measurable and important contribution to the geochemical mobility and cycling of elements. Excellent scientific book on humic substances - the real substance of life.

The properties of humic substances (HSs) in plants, soils and sediments regulate the environment and affect all aspects of like, yet they are only very imprecisely understood. This volume presents work on HSs including instruments and techniques being developed to throw more light on their structure and relationship to macro- and micro-scopic properties.
