Investigation of eco-hydrological processes and feedbacks in the soil-plant continuum at different spatio-temporal scales (C01)

主要目标是：（a）使用CLM分析土壤水文条件、树木水分利用和生长之间的土壤-植物-大气相互作用;（B）使用稳定同位素推导代表ParFlow地下水流的参数和边界条件;（c）通过比较草地、森林和森林砍伐集水区，研究土地利用变化对水传播时间的影响;以及（d）使用（a）的结果，（B）和（c）优化土壤水分（SWC）场的TerrSysMP模拟。本地和非本地控制将通过建模和派生的缩放方法进行调查，将优化数据同化方法内的TR 32。

Key goals are (a) to analyze soil-plant-atmosphere interactions between soil hydrologic conditions, tree water use and growth using CLM, (b) to derive parameters and boundary conditions for representing subsurface water flow of ParFlow by using stable isotopes, (c) to investigate land-use change effects on travel times of water by comparison of grassland, forest and deforested catchments, and (d) use results of (a), (b) and (c) to optimize simulations of TerrSysMP of soil water content (SWC) fields. Local and non-local controls will be investigated by modeling and derived scaling approaches will optimize data assimilation approaches within the TR32.
