기복이 심한 한반도 중서부 산림경관에서 기후가 순일차생산(NPP)에 미치는 영향에 대한 모사연구

초록

We have investigated microclimatic controls on the spatiotemporal variations of net primary production(NPP) of a rugged forested watershed using the process-based biogeochemical model (BIOME-BGC). Tovalidate the model simulation of water and carbon cycles at the plot scale, we have conducted field surveyover deciduous broadleaf forest (DBF) and evergren needleaf forest (ENF) since 2000. The modeledfield measurements. The modeled seasonal changes of NPP showed high corelation with air temperaturebut no significant correlation with water related parameters. The precipitation frequency turned out to bethe best climatic factor to explain the annual variation of NP. Furthermore, NPP of ENF was moresensitive to precipitation frequency than that of DBF. With changes in vegetation cover and topography,magnitude of NP. Despite the annual precipitation of 1,400mm, NPP at the study site was constrained bythe amount of water available for the vegetation. Such a modeling result should be verified by the field measurements.
