其他摘要：The paper aims at analysing the influence of progress of weather (temperature and precipitation) in 2012 as the reference year on the quality of energy wood chips made entirely from logging residues. The quality data represents the logging volume totalling 44,971 cubic metres; the logging residues were gathered on a.total area of 108.36 hectares. The production data was provided by forest enterprises and trade companies producing energy wood chips and represented 258 business cases. The climate data was drawn from the database of the Czech Hydrometeorological Institute, as aggregated data, the effort being to eliminate local climatic fluctuations. It can be summarised based on the results of the work that the average monthly temperature and monthly precipitation in 2012 have a.very weak influence on the moisture and the calorific value of wood chips produced from logging residues. For the ash content, the dependence can be fully eliminated. In the case of dependent variables of moisture and calorific value, the statistical analysis results were slightly better: the correlation between moisture & calorific value and precipitation was moderately significant; the same applied to the data when correlated with temperature.
