摘要

This study presents a system which enables the assessment of selected stand characteristics. The system consists of tariffs for dominant height, mean diameter and basal area, The system is based on single eco-regions in Germany but can be applied nation-vide. The tariffs were developed for the tree species spruce, fir, pine, larch, beech, oak, Douglas fir and deciduous trees. The system can be applied to roughly reproduce stand structures at a forest estate and regional level. It enables a comparison of eco-regions in Germany and allows a validation of growth models. Fur a parameterisation of tariff functions, the data from two different sources was used. Firstly, the tree data of the south--western inventory 'points from the Federal Forest Inventory (Western Germany) and secondly, the point-related data from forest management records (East Germany). The constructed stand tariffs merely show the statistical relationships between the characteristics of die stands, in contrast to growth models used in forestry (yield tables, forest growth simulators), which describe forest development.
