Research
Since the calibration of flux measurements between forest stand and boundary layer of the atmosphere and the evaluation of respiration processes has been required, an automatic system for continuous measurement of CO2 effluxes from soil has been constructed. At first, the analysis of available measuring methods has been done. A closed gasometrical system was the most suitable for the construction of automatic CO2 flux measurement system - SAMTOC (Czech acronym). During the wintertime 2000/2001 the system was tested from the point of view of its functionality, at the beginning of the vegetation season 2001 was installed at the research site Bílý Kříž on Beskydy Mts. and its test operation started. The results of the operation test in 2001 showed the suitability of the suggested solution for soil respiration detection and possibilities of its modelling according to the actual soil temperatures. From the 2002, the SAMTOC system was extend in measurement of woody tissue (stem).
