current periodic volume increment - Opis:
- The conditions of using concentric sample plots in a successive inventory were researched. New definitions of ‘ingrowth' and ‘overgrowth' were introduced. As there is a possibility that sample plots could be located at stand edges, a new method POW_K of converting data from concentric plots was developed. The calculation results using this method were compared with the results obtained by the traditional method WSP. Two variants of obtaining inventory results for the whole forest district were taken into consideration – with and without stratification. Due to the value of mean errors of assessment of significant characteristics – volume and current periodic volume increment – the WSP method turned to be better – particularly in the variant with stratification. However, this method cannot be applied for utilizing the results of measurements of edge plots.
