项目摘要

This research has two research themes ; 1) A Study on the Interaction of Global Environment with Vegetation and 2) A Study on the Anthropogenic Intervention in the Global Carbon, Nitrogen, and Phosphorus Cycle.As for the first theme, this study coordinated a DGVM, which uses atmospheric conditions and terrestrial vegetations as inputs and simulates the processes of the near-surface exchange of energy, carbon, nitrogen and water, the process of phenology, the process s compete between plant types, and the processes of carbon and nitrogen balance, to be used as a platform of analyzing the interaction of global environment with vegetation. To evaluation its applicability, IBIS(the Integrated Biosphere Simulator) is employed and applied to Asian region to evaluate long-term variation of vegetation type. Good agreement is obtained in the low and middle latitude region, but the high latitude region, the amount of plants are estimated.As for second theme, this study developed a method of estimating global carbon, nitrogen, and phosphorus flows induced by human activity and proposed a Global Carbon, Nitrogen, and Phosphorus Account Table (GCNPAT) to describe these flows. To estimate domestic flows, we reconcile reported production and consumption values with material balances using material densities. And to estimate trade flow, we used the RAS algorithm. We applied the account system to the year from 1971 to 2002. The result showed that human activity harvest 13,558TgC, 212TgN, 35.7TgP from natural resources in 2002. These flows increased about 1.7 fold in these 30 years. As for the wastes, human generated 1,806TgC of agricultural residue and 86.5TgN of animal and human excreta in 2002. Agricultural residue has the great potential to be an energy resource, and animal and human excreta have the great potential to be fertilizer resources.

本研究有两个研究主题； 1）全球环境与植被相互作用研究和2）全球碳氮磷循环人为干预研究。对于第一个主题，本研究协调了DGVM，以大气条件和陆地植被为输入，模拟近地表能量、碳、氮和水的交换过程、物候过程、植物之间的竞争过程类型、碳氮平衡过程，作为分析全球环境与植被相互作用的平台。为了评估其适用性，采用IBIS（综合生物圈模拟器）并将其应用于亚洲地区，以评估植被类型的长期变化。在低纬度和中纬度地区获得了很好的一致性，但在高纬度地区，植物数量是估计的。至于第二个主题，本研究开发了一种估计人类活动引起的全球碳、氮和磷流量的方法，并提出了全球碳、氮和磷核算表（GCNPAT）来描述这些流量。为了估计国内流量，我们使用材料密度将报告的生产和消费值与材料平衡进行核对。为了估计贸易流量，我们使用了 RAS 算法。我们将核算系统应用到1971年至2002年。结果显示，2002年人类活动从自然资源中收获了13,558TgC、212TgN、35.7TgP。这些流量在这30年中增加了约1.7倍。在废弃物方面，2002年人类产生了1,806TgC的农业剩余物和86.5TgN的动物和人类排泄物。农业剩余物具有巨大的能源潜力，而动物和人类的排泄物具有巨大的肥料资源潜力。
