Use of Rough Sets analysis to classify Siberian forest ecosystems according to net primary production of phytomass

This paper attempts to identify attributes that are considered essential fo r a development of sustainable forest management practices in the Siberian forests. This goal is accomplished through an analysis of net primary produ ction of phytomass (NPP), which is used to classify the Siberian ecoregions into compact and cohesive NPP performance classes. Rough Sets (RS) analysi s is used as a data mining methodology for the evaluation of the Siberian f orest database. In order to interpret relationships between various forest characteristics, relationships known as interesting rules are generated on a basis of a reduced problem description.
