Geographic change of form
The geographic change of form (after Hermann Lautensach 1952, hence also called Lautensach'scher form change ) is a concept for the geographical consideration of spaces . The sequence of landscape forms is seen as a law. The concept is particularly used in regional geography and is based on geography . Lautensach's concept does not include any time aspect and therefore cannot be applied to processes that are relevant to space.
Four types of form change
The geographic change of shape is divided into four types. The first three can be understood in such a way that they are oriented towards the three Cartesian axes through a considered region, the last type takes into account the center of a region in relation to its surroundings.
Planetary ( north-south or polar-equatorial )
deals with the changes in the climate , the soil and the vegetation in north-south direction, i.e. from the north pole or south pole to the equator . The results are the climate and vegetation zones, the cause of which is the different solar radiation due to the inclination of the earth's axis (ecliptic).
West-East ( maritime-continental )
explains the changes in climate, soil and vegetation in a west-east direction, i.e. from the sea to the interior . The results are strips of increasing continentality , the causes for this are the ocean currents , winds and the distance from the coast.
Hypsometric ( vertical )
Further concepts for spatial consideration from a regional perspective are the regional studies scheme according to Hettner (1932), the dynamic regional studies according to Spethmann (1928) or the geosystem theory that emerges from geographical landscape research .
