项目摘要

Huge amount of tropical peat distribute in Kalimantan, Indonesia, which face a crisis of decomposition by frequent fire because of unruly development and irregular logging. As CO_2 by fire and microorganisms are tremendously, it is observed CO_2 increase in atmosphere clearly. Therfore, we have studied here to rehabilitate forestry and to conserve peat soil in devastated peat land. Obtained results are as follows.(1)Estimation of environmental values1)Dynamics of chemical compounds and lignin degradationDynamics of chemical compounds was estimated in peat soil, river, and lake, for which many samples were analyzed. Many number of white rot fungi was isolated from peat soil and wood, some of which have activity to degradation lignin, PCB, Dioxin, so on.2)Observation of microclimate in tropical peat forestryMicroclimate and CO_2 flux were observed at 1)Natural forestry in Kalampangan, which became more dry by affecting on canal digging,2)Burned forestry in Kalampangan, which also became more dry by affecting on canal digging, and 3)Natural laboratory in Setia Alam, which is kept natural condition. We found that disturbed forestry became now carbon source because of low photosynthesis and peat decomposition by microorganisms, which is first finding in the world.(2)Region management system1)Forestry rehabilitationAs Shorea balangeran and S.selanica show high revival ratio and good growth in peat soil, we used these species for rehabilitation in devastated peat land near Palamgka Raya in Central Kalimantan.2)Human Dimension ProgramIt is very important environmental education for environmental conservation. We develop environmental education program, then teach school students and regional inhabitants. Also we develop an integrated model on rehabilitation and conservation of peat land by the regional inhabitants.

大量的热带泥炭分布在印度尼西亚的卡利门坦（Kalimantan），由于不守规矩的发育和不规则的伐木而面临频繁火灾的危机。由于火灾和微生物的CO_2非常大，因此可以清楚地观察到CO_2的增加。因此，我们在这里进行了研究，以修复林业并保护泥炭土地上的泥炭土壤。获得的结果如下。（1）环境价值的估计1）化合物和木质素降解化合物的动力学在泥炭土壤，河流和湖泊中估计，为此分析了许多样品。从泥炭土和木材中分离出许多白色腐烂真菌，其中一些具有降解木质素的活性，PCB，二恶英，等等。卡兰班加（Kalampangan）通过影响运河挖掘而变得更加干燥，2）卡兰班加（Kalampangan）烧毁了林业，这也通过影响运河挖掘而变得更加干燥，而3）Setia Alam中的天然实验室，该实验室保持自然状态。我们发现，由于微生物的光合作用和泥炭的分解低，这是世界上首次发现的林业。（2）地区管理系统。泥炭土，我们使用这些物种在卡利曼坦中部的帕拉姆加·拉亚附近的破坏性泥炭土地上进行康复。2）人类维度计划是对环境保护的非常重要的环境教育。我们制定环境教育计划，然后教学校学生和地区居民。同样，我们还开发了一个综合模型，该模型在地区居民对泥炭土地的康复和保护方面。
