ABSTRACT- Our research on Mures River Meadow, Romania had as its main objective to study the flora and vegetation units in order to systematize the scientific fundamentals of conservation methods for the proposed perimeter as a natural park. Our results show that the bioforms have the following values: hemicryptophitae (56.18%), geophyitae (13.4%), annual terophytae (8.76%), chamaephytae (6.7%), megaphanerophytae (6.18%), biannual terophytae (5.15%), mesophanerophytae, nanophanerophytae, helohidatophytae, epiphytae. Phytogeografic analisys of the Mures River Meadows flora has evidentiated the following percents: euroasiatic elements (39.69%); central-european elements (26.28%); termophylae elements (submediterranean, 5.67%; mediterranean, 4.63%; balcanic, 1.03%). Ecological spectrum of Mures River Meadow flora from Lipova-Nadlac region (Romania) show that, related to humidity, mesophytae (45.87%) and xeromesophytae (43.81%) record similar proportions, fact that indicates a mesoxerophil forest vegetation caracteristic to dome regions found in South-West of Romania, dominated by Quercus cerris and Quercus frainetto. After temperature parameters most of the species are mesothermal (71.20%) followed by moderate-termophil species and termophils (15.80%) that are found in a high percentage for the latitude of this region. Soil reaction indications show that the majority of the species are acid-neutrophil (70.61%) followed by amphytolerant species (20.6%). In reduced proportions we found neutral-basophil species (4.12%) and acidophils (4.63%). We concluded that the multiple flora analisys of the studied region shows the main pedo-climatic features. Thus if we compare the vegetation by the adaptation to the ecological factors we concluded that the mesoxerophytae and the mesophytae species have the most abundant representation.
