Development of validation method for the scaling up of carbon flux simulation using ecological process models

根据万年青针叶林和落叶阔叶林的小气候和生态观测资料，对SATECO生态过程模式进行了调整和修正。利用SATECO模拟了岐阜县大八贺川流域的碳通量，利用卫星图像对植被类型进行了分类，并利用机载激光测量的冠层高度数据和分类图估算了两个时期的木本干生物量。生物量增长（木本净初级生产力，NPP）计算为两个干生物量估计值之差。将SATECO模拟的NPP与木本植物NPP进行了比较，两者在空间分布和数值上的差异可以反映模拟结果的合理性。

An ecological process model SATECO was tuned and revised based on micro climatological and ecological measurements at evergreen conifer and deciduous broadleaved forests. Carbon flux was simulated by SATECO with climate data over Daihachiga river basin in Gifu prefecture.Vegetation type was classified using satellite imagery and woody dry biomass was estimated at two periods using canopy height data from airborne laser measurements and the classification map. Biomass growth (woody net primary production, NPP) was computed as the difference of the two dry biomass estimations. Simulated NPP by SATECO and woody NPP were compared each other and differences of the two NPP in spatial distribution and NPP values could show appropriateness of the simulation result.
