This study presents a geographic information systems-based multi-criteria site selection of non-hazardous regional landfill in Polog Region, Macedonia. The multi-criteria decision framework integrates legal requirements and physical constraints that relate to environmental and economic concerns and builds a hierarchy model for landfill suitability. The methodology is used for preliminary assessment of the most suitable landfill sites by combining fuzzy set theory and analytic hierarchy process (AHP). The fuzzy set theory is used to standardize criteria using different fuzzy membership functions while the AHP is used to establish the relative importance of the criteria. The AHP makes pairwise comparisons of relative importance between hierarchy elements grouped by environmental and economic decision criteria. The landfill suitability is achieved by applying weighted linear combination that uses a comparison matrix to aggregate different importance scenarios associated with environmental and economic objectives. The results from the study suggested that a least suitable landfill area of 1.0% from the total is generated when environmental and economic objectives are valued equally while a most suitable landfill area of 1.8% area is generated when the economic objective is valued higher. Such results are aimed for enhancement of regional landfill site selection in the country that is compliant with modern EU standards. 相似文献

Flysch sequences develop normally from pelagic sediments, over a pre-flysch transitional unit, or from a well-developed transgressive base. A different situation has been observed in the western portion of the Upper Eocene flysch basin of Ov?e Pole, Macedonia, where deep-water turbidites appear almost directly over the eroded basement, transgressively overlapping the preexisting submarine relief. These relationships are explained as results of successive phases of subsidence in the basin. The outcrop area, situated between Titov Veles and Gradsko, represented a surface without deposition in the early depositional stages. Later subsidence introduced a turbiditic deposition into the domain without a break in sedimentation. Such cases may occur also in other flysch basins where lateral migration of the main depositional trough took place during the sedimentation. 相似文献
