Global Carbon Circulation of Plant Cell Wall Components -Formation Mechanism of Fossil Resources-

2003年12月至2005年11月，对印度尼西亚东加里曼丹、泰国南部和越南湄公河三角洲的热带泥炭沼泽的河流、湖泊和沼泽的水样和沉积物进行了定期分析。根据GPS数据和航空照片提供的信息，通过现场视察决定取样地点。由于泰国南部的政治安全问题，从北海道Bibai市Ishikari-riber盆地的泥炭沼泽中采集了大量的沼泽水，以研究溶解有机物的结构特征。泥炭样品也收集了不同深度的核心采样器在泰国南部的Bacho沼泽。分析了泥炭样品的化学特征，探讨了植物细胞壁组分的生物改性及其增溶机理。植物细胞壁受到 ...更多信息 在亚临界和超临界水条件下的反应，以研究动力学成为化石资源。在反应产物中检测到大量的烃类和芳香族化合物的产生，这些化合物与原油的组成是相容的。1.利用从热带泥炭沼泽采集的水和泥炭样品建立了分离、定性和定量分析的程序。根据现场调查和实验室工作的数据，讨论了水溶性和颗粒有机物。证实了泥炭沼泽褐色出水的来源是微生物显著改性的水溶性木质素。从土登原始泥炭沼泽（8，800公顷），超过35，000 tC yr-1的木质素被排放到河流中。3.证实泥炭沼泽中的溶解有机质容易与金属离子形成螯合物，并以沉积物的形式积累。此外，还研究了有机质在退化地区如沙漠和碱性土壤中的积累和动态。少

Water samples and sediments at rivers, lakes and marshes were collected from tropical peat swamp in East Kalimantan of Indonesia, southern Thailand and Mekong Delta of Vietnam, dissolved organic carbon, particulate organic matters and inorganic ions were analyzed at regular intervals from December 2003 to November 2005. Sampling sites were decided by on site inspections based on information from GPS data and aerial photographs. Huge amounts of swamp water to be examined structural characteristics of dissolved organic matters were collected from the peat swamp at Ishikari-riber basin, Bibai-city, Hokkaido, because of the problems on political security at southern Thailand. Peat samples were also collected from various depths using a core sampler at Bacho swamp in southern Thailand. Chemical characteristics of peat samples were analyzed and biological modification of plant cell wall components and mechanism of water solubilization of them were discussed. Plant cell walls were subjected i … More n reactions under sub-critical and super-critical water conditions to investigate dynamics to be fossil resources. The production of huge numbers of hydrocarbons and aromatic compounds, which are compatible with the composition of crude petroleum, were detected in the reaction products.1.The procedures for separation, qualitative and quantitative analyses were established using water and peat samples collected from tropical peat swamps.2.Dynamics of soil, water-soluble and particulate organic materials were discussed based on data from on-site investigation and laboratory works. It was confirmed that the origin of brown colored water flow-out from peat swamp was water-soluble lignin, which was remarkably modified by microorganisms. From To Daeng primary peat swamp (8,800 ha), more than 35,000tC yr-1 of lignin were discharged in rivers.3.It was confirmed that dissolved organic matter from peat swamp was easily formed chelates with metal ions, and accumulated as sediments.In addition, accumulation and dynamics of organic matter in degraded area such as desert and alkaline soil were also investigated.
