The main objectives of the present study were constructing and validating the elemental dynamics kinetic model that described the ecosystem processes for acquiring mineral resources by biosphere. The linear relationship was observed between the rates of net primary production and soil acidification. The alteration of these processes after human reclamation of forests for agricultural use was quantitatively described. The impact of soil acidity on the soil microbial processes was also quantitatively evaluated based on the two-step decomposition model including both solubilization and mineralization of polysaccharides and two-step metabolism by soil microorganisms in substrate utilization.

本研究的主要目的是构建和验证描述生物圈获取矿产资源的生态系统过程的元素动力学动力学模型。净初级生产力与土壤酸化率呈线性关系。定量地描述了人类开垦森林后这些过程的变化。基于多糖的溶解和矿化两步分解模型以及土壤微生物利用基质的两步代谢模型，定量评价了土壤酸度对土壤微生物过程的影响。
