THE INFLUENCE OF FORESTS FROM LUNCA MUREŞULUI NATURAL PARK ON GREENHOUSE GASES LEVELS.

The paper aims to analyze the influence of the stand characteristics in two areas of the Lunca Mureşului Natural Park, on the main greenhouse gases in the atmosphere (O3, NH3, NO2). In the first part, an extensive bibliographic study was carried out, regarding similar research referring to greenhouse gases in generally and O3, NH3 and NO2 in specially, and the relation of these greenhouse gases to forest vegetation. The working method regarding data collection in the period 2014-2019, the types of gases analyzed, the types of collection pads used, the exposure times of the collection pads were presented, together with the working method for data processing. The results were obtained by analyzing relation of certain characteristics of the stand (age, volume, stand density) with concentration of studied greenhouse gases on vegetation season from the period 2014-2019. The obtained results were discussed in the context of other current research in the field and the most important aspects were presented as conclusions at the end of the paper. [ABSTRACT FROM AUTHOR]
