The Medves Area lies close to the Hungarian-Slovak boundary in North hungary. Having 'horst-graben-type' geological structure it can be characterised by steeply emerging horst-like hills and between them narrow trenches and deeply dissected erosional valleys. The recent morphology of the Medves Area is determined by four main elements: the structure, the petrographic setting, the exo-genic processes and the anthropogenic effects. In spite of the domination of the Oligocene-Miocene sedimentary rocks great part of the area is covered by Pliocene basalts having either stratovolcanic structure or consisting of only lavas, forming lavaplateaus, small cones, dykes or necks. In spite of the strong denudation their original form dominates yet. The decrease of the sheet of the Medves Plateau was considerable only on the rims by parallel retreat. In the southern part of the Medves Area the evolution of the landscape was determined mainly by exogenic processes. The great density of the valleys is very significant,

Examples for Application of Gravitational Model in the Investigation of Spatial Structure

引用

Journal of Mathematics and System Science 2013年第10期3卷 477-490页

作者： Aron Kincses Geza Toth Hungarian Central Statistical Office 1024 5-7. Keleti K. str. Budapest Hungary

In this paper the authors wish to introduce an application of the gravitational model through two concrete examples. In their investigation the gravitational model was transformed to analyze the spatial structure of Europe, and the impact of accessibility in hungary. In this analysis not only the size of gravitational forces but their direction can also be measured. Displacements were illustrated by a bi-dimensional regression, which gives a new perspective to the investigation of spatial structure.
