geometric and natural convention of determining indicators of forest diversity
uneven−aged forest
diversity characteristics - Opis:
- There are two conventions of determining indicators of forest diversity: geometric and natural. Indicators in the geometric convention are determined from the ratio of differences in the values of the real characteristic to the value of the characteristic adopted as a comparative norm. Indicators in the natural convention are determined from the ratio of differences in the values of a characteristic in the real world to the mean value of that characteristic by standard deviation. The indicator−based assessment of forests in Poland is based on the geometric convention of similarities and standards included in yield and stand volume increment tables. This convention of similarities (map and plan scales) taken directly from technology has no natural justification. Therefore, it is necessary to determine indicators of forest diversity based on natural convention with special reference to the uneven−aged forests based on natural forests.
