Abstract: The aim of this study is to modify, to adapt, and to apply to the Romanian urban landscape a quantitative method proposed and applied in Spain by Cañas Guerrero (1995). Several specific parameters and variables of a given landscape are analyzed and assessed. Then, using mathematical formulae, one gets a score which indicates the quality of the studied landscape.
Abstract: The physiognomic complexity as the main characteristics of the Bucegi Mountains landscape is the result of lithology, structure, tectonics and high altitude, which led to the vertical zoning of modelling conditions. There can be separated: the landscape of erosion outliers and the structural plateaus from the alpine area, the landscape of Prahova scarp and that of the plains at the Bucegi mountain feet. Up to about 2200 m, the landscape of erosion outliers and structural plateaus was mostly affected by human activities, mainly the tourism and uncontrolled grazing. The landscape of the Prahova scarp of the Bucegi is notable by high touristic anthropization on the slopes of the Vârful cu Dor – Furnica – Piatra Arsă mountains, neighbouring Sinaia, where there are frequent degradations of the roads and paths improperly located and maintained. The Bucegi slope northwards of Piciorul Pietrei Arse still preserves the natural landscapes in dynamic equilibrium (which possess a great tourist and alpinist potential). At the scarp foot, following the modelling of the Cretaceous flysch and sedimentation of large talus material, there resulted a relief with smooth field – plai (Plaiul Fânului,Plaiul Coştila, Munticelu, Plaiul Stânei, Plaiul Peleşului, Plaiul Furnica) – rounded interfluves with a slope below 300, compared to those over 300 (often over 500 within the scarp.
Abstract: After Hungary was asked according to the Territorial Agenda (TA), agreed in the informal ministerial meeting under the German Presidency in May 2007, it undertook the responsibility to evaluate and review the TA and update the closely related Territorial States and Perspectives of the European Union (TSP). The TA has a key importance due to the fact that it had been the first document which identified joint action oriented framework of spatial (territorial) policy on the EU level. The TSP (as basic evidence of the TA) in its more synthetic chapters attempted to identify more integrated territorial structures of the European territory including main geographic dimensions such as north-south and east-west dichotomies, polycentricity and urban-rural patterns. Due to the changes in the driving forces and the new conditions of an enlarged EU, the content and also the function should be revised. The paper is aiming to introduce some of the main findings of the TSP/ TA revision process with special reference to the new aspects and trends related to the territorial structures of the Union and the spatial structure of Europe. Finally, some solutions will be introduced which could help to enhance the currently not enough strong territorial approach within TSP and TA.
Abstract: Uncontrolled subterranean coal fires, mainly developed through the process of self-ignition, represent a challenging hazard of local dimension, but with global-scale distribution. One important effect of this spontaneous ignition process is the surface subsidence. Porosity and particle size fraction of the coal particles in the deposit, water and oxygen play the main role. Anina sterile heaps present a non-typical situation of waste-coal self-ignition. The fine coal is found in the sterile heaps distributed all over the actual urban area, being covered by human activities and residential buildings, so that, the human risk is present in several forms.
Abstract: Although a country with a relatively small area, Romania has a variety of natural resources, which in time were favourable prerequisites to the development of processing activities. Most of these resources are not able to provide entirely the requisite, but cover parts of it in certain proportions. The territorial distribution of natural resources and the different cultural influences have fostered the development of certain regions or industrial centres of the country. The dynamics of the industrial exploitation of these centres has grown continuously, reaching a paroxysm in the centralised regime, when some of the resources have been largely exhausted. Rapid and often risky industrialisation, relying mainly on the basis of propaganda and not of economic efficiency has led to a falsely balanced development. New industrial structure, both territorial as well as sectorial has proven ineffective in the very first year of transition from the centralised system to the market economy.
