This study consists of the following three sub-themes : 1) quantitative evaluation of temporal variability of carbon cycle parameters along with secondary succession ; 2) examination of sustainable carbon sequestration within developing ecosystems in terms of a succession/carbon dynamics model ; 3) temporal variation of soil organic carbon with primary succession. Our chronosequence study of secondary succession in Sugadaira, Nagano prefecture, used for the following ecosystem sequence : Artemisia-dominant grassland, Miscanthus-dominant grassland, Populus-dominant forest, Pinus-dominant forest, Quercus-dominant forest and Fagus-dominant forest. Carbon sequestration within the plants increased with succession. However, litter carbon showed no increase or decrease with succession. Soil carbon increased in herbaceous sere, and decreased in early forest stages. Thus, our results demonstrated that secondary succession influenced the size of carbon pools within the ecosystems. The measured results were confirmed by a simulation in terms of a succession/carbon dynamics model. In primary succession study (Miyakejima study site), soil organic carbon increased from a naked land to a climax stage.

这项研究由以下三个子主题组成：1）碳循环参数的时间变异性和继发性依据的定量评估； 2）根据继承/碳动力学模型来检查开发生态系统内的可持续碳固化； 3）土壤有机碳的时间变化，主要继承。我们对长野县Sugadaira的次级演替的计时序列研究，用于以下生态系统序列：贫农虫优势草原，卑鄙的草原，占主导地位的草原，Populus占主导地位的森林，Pinus-Pinus-Ponsiminant森林，Quercus森林，Quercus-Pagus-Pagus-Pagus-Pagus-Pagus-Pagus-Parionant-Pormininant Forest。植物内的碳固换随后增加。但是，垃圾碳显示出随着继承而没有增加或减少。草本菌的土壤碳增加，并在早期森林阶段减少。因此，我们的结果表明，次要继承影响了生态系统内的碳池的大小。通过替代/碳动力学模型的模拟证实了测得的结果。在主要继承研究（Miyakejima研究地点）中，土壤有机碳从裸露的土地增加到高潮阶段。
