The vegetation accounts for the biomass produced by the surface soil layer made up of inorganic elements and exposure to the Sun. The overexploitation of natural resources by heavy industry, excessive agriculture and urban development represent the most important way of biodiversity degradation, leading to the extinction of a large numbers of species. The natural vegetation plays a decisive role in the conservation of plant diversity, of animals and of the biocenosis and of the ecosystems. The goal of the study was the mapping and the delimitation of some protected areas in Timis county, areas of national interest that correspond to the IVth IUCN category (International Union for Conservation of Nature). The measurements taken in the field have been carried out by means of GNSS technology through RTK method, being the most suited by point of view of precision and fastness for recording all the details. The drawing up of the vegetation maps, or of another type, knowing the eco-systemic life layer of the whole living environment which is necessary. The following steps were taken into consideration for the project: field recognition, filed measurement, office works. The methods used in the mapping process are modern methods, and allowed the delimitation of the studied areas and their transposition in a compatible format, used in many sectors of activity: CAD or GIS.
The lignite mining extraction within the mining perimeter in Rovinari is carried out through mining works in the open, by using large equipments for the excavation, transport and storage of the mining material. These surfaces are currently being set up in the area of level two of the dump, the west and north-west part of Rovinari pit. In order to carry out the set-up works and of follow-up of the stability of the pit levels it is necessary to maintain the triangulation network.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
