Water Relations at Different Scales
The comprehensive data set of meteorological, hydrological, soil physical and plant physiological measurements permits a detailed inquiry into how ecosystems use water and how the water cycle is coupled with other cycles in agricultural and forest ecosystems. Since characteristic features of such cycling processes are distinctly scale-dependent and comprehensive water budgets are subject to detailed discussion in Chapter 9 of the present book, in the following the spatial scale is restricted to the range from leaves to stands of the ecosystems investigated in the core area of research (cf. Chapter 3). Thus, the first part presents water relations at the leaf scale, in the second the focus is on the ecophysiology of water exchange at the stand level, and finally there is a comparison of the empirical results of this enquiry with results of modelling approaches. The methodology underlying both measuring and modelling procedures is summarized in Section 1.3.
