摘要: Understanding water relations is necessary to assess forest vigor, since numerous plant processes are influenced by the status of soil and plant, e.g., growth, nutrient uptake, production release growth substances leaf gas exchange (Bradford Hsiao 1982; Schulze 1986). However, availability for sustaining these not only dependent on control mechanisms at individual level, but also determined canopy structure boundary conditions stand level (Jarvis MacNaughton 1985; Jarvis 1987). The balance between rainfall evapotranspiration determines a large extent transport into out ecosystem. Water percolating through profile carries nutrients which may be leached below root zone groundwater (Ulrich physical properties will in turn affect uptake.
