Полученные результаты позволили прийти к выводу, что БИК-спектры могут использоваться как информативный показатель для установления видовой принадлежности древесных растений, а также для отслеживания происхождения лесоматериалов и обнаружения фактов незаконных рубок. Показана возможность интерпретации полученных спектральных данных с применением формального независимого моделирования аналогий классов и дискриминантного анализа проекций на латентные структуры. Построены стабильные работоспособные классификационные модели для дифференциации диптерикса душистого и диптерикса многолистного, а также граба обыкновенного различного географического происхождения.</p></abstract><trans-abstract xml:lang="en"><p>The article addresses practical aspects of applying the spectroscopy in the near infrared region method when conducting forensic examinations of wood. Based on the obtained results, it has been concluded that the NIR spectra can be used as an informative indicator to determine the species of woody plants, as well as to track the origin of timber and to detect the facts of illegal logging. The authors demonstrate the possibility of interpreting the obtained spectral data using formal independent class analogy modeling and discriminant analysis of projections onto latent structures. They have also built stable workable classification models to differentiate Dipteryx odorata (Cumaru) and Dipteryx panamensis (Cumarurana), as well as common hornbeam (Carpinus betulus) of various geographical origin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>древесина</kwd><kwd>БИК-спектроскопия</kwd><kwd>видовая принадлежность</kwd><kwd>место произрастания</kwd><kwd>SIMCA</kwd><kwd>PLS-DA</kwd><kwd>классификационные модели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wood</kwd><kwd>NIR spectroscopy</kwd><kwd>species identification</kwd><kwd>place of growth</kwd><kwd>SIMCA</kwd><kwd>PLS-DA</kwd><kwd>classification models</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Cabral E.C., Simas R.C., Santos V.G., Queiroga C.L., da Cunha V.S., de Sá G.F., Daroda P.J., Eberlin M.N.
