The representatives of the traditional schools of terminology have formulated five basic principles of term creation and application. However, as the amount of scientific technical information is rapidly increasing, the organization of special knowledge has changed. Today the processes of term formation, description and application involve not only linguists, terminologists, and the specialists of the respective scientific and technical field, but also, e.g. IT specialists, who have developed a great number of different contemporary software programs, which are designed for the processing of information, and, thus, facilitate classification, collection and application of terms. It results in elaboration of new mechanisms for the identification, retrieval and processing of a great number of newly created terms. Therefore, the scientists have recognized that the traditional theory of terminology has a variety of restrictions, which should be re-evaluated, as to the process of contemporary term formation, its implementation in the text and alignment across the languages. The author of the present paper aims at the analysis of the traditional principles of terminology research against the principles relevant for the formation, description, systematization and application of modern terminology, which are formulated by the author of the paper, focusing on the investigation of their implementation particularly in the thematic field ‘environment an ecology’, as the development of terminology of the present field most brightly demonstrates the modern trends in the process of novel terms creation.
