In any terrestrial area, but especially in the case of mountainous areas, the spatial distribution of vegetation is conditioned by a series of natural factors such as relief, climatic factors or soils. From another point of view, the distribution of vegetation is different, depending on the phenophases, implicitly on the observation period, during the growing season. In this context, the aim of the work was to analyze the vegetation coverage of the grasslands in the Poiana Rusca Mountains, by applying the Normaliz...

The way of land use and implicitly the spatio-temporal distribution of plant species are subject to quantitative and qualitative changes, under the influence of natural and/or anthropogenic factors. Appreciation of the spatio-temporal "mobility" of vegetation can be done through different work protocols, some of which are geomatic methods applied to satellite images. In this context, the purpose of this study is to analyze the trends in the dynamics of vegetation and land use, over a period of approximately 35 yea...

The necessity and opportunity of research by fast and efficient remote sensing methods and means derives from the fact that pratological investigation involves a great deal of time and resources, repeated missions on the ground and the involvement of a larger number of specialists. With the advanced technique (remote sensing methods and means), the main purpose of this study is to monitor grassland in the analyzed area and quantify the chlorophyll concentration of plants on the basis of the Normalized Difference V...

The statistical data on the structure of the land fund in Arad County, located in western Romania, highlights changes in the temporal evolution of the surfaces with different uses. One of the causes of these ?migrations? is changing the land use category, for various reasons, legal or technical aspects. In this context, the present paper describes the evolution of the surfaces and the stages that need to be taken to change the land use category, the case study being the ?transformation? from arable into pasture. I...

Agriculture, regarded as one of the oldest occupations of mankind, practiced by different techniques and differentiated means according to the general level of development, is still the main socio-economic supporter at the level of the analyzed area. If in Romania's "agricultural past" the attention was concentrated on maximum, immediate and "indifferent" production, at present, under the action of international politics, there are remarkable administrative, organizational and technical capitalist nuances, dictate...
