Natural areas in Saxony

from Wikipedia, the free encyclopedia

The natural structure of Saxony shown here was established between 1994 and 2001 by a working group called "Natural balance and regional character" of the Saxon Academy of Sciences in Leipzig as part of the research and development project "Natural areas and natural area potentials of the Free State of Saxony on a scale of 1: 50,000 as Basis for state development and regional planning ”. This was funded by the Saxon State Ministry for Environment and Agriculture and the Saxon Ministry of the Interior.

The basis of the structure was the nationwide comprehensive recording of the smallest physiogeographic spatial units ( physiotopes ). These were regularly aggregated into larger units ( nanogeochores and microgeochores ) using the natural spatial order method . For each of the microgeochores determined in this way there is a 9-page documentation sheet, the cartographic representation was made on 55 sheets on a scale of 1: 50,000 ("natural space map of Saxony"). In further aggregation steps, the approx. 1445 microgeochores were combined into mesogeochores and these finally into 28 macrogeochores (see list of natural spatial units in Saxony ). From the level of the microgeochore upwards, each natural area was given an individual name, with newly created names following certain conventions. The classification of the macrogeochores in natural space units of a higher level is indicated by the so-called "Saxon natural regions", which were also given their own names, but are largely on the political borders and in fact represent excerpts from far more extensive units.

Comparison with the natural spatial structure according to Meynen and BfN

In the 1950s Emil Meynen had divided Germany into main unit groups (two-digit numbers), main units (three-digit numbers) and sub-natural areas (decimal places). For the time being, this was the last uniform processing for the whole of Germany, afterwards such an overall representation was not possible for many years because of the German division. The research and recording of the natural areas in Saxony was nonetheless continued and has led to extensive changes since then. Since the area covered by the “Natural Map of Saxony” is limited to the territory of the Free State of Saxony, planning throughout Germany, e.g. B. on the part of the Federal Agency for Nature Conservation, used the old Meynensche classification for Saxony to this day. However, it no longer plays a role in the relevant professional practice at state level.

The following main Meynen units or groups are at least z. T. in Saxony (in brackets the new numbers according to BfN):

Low mountain range threshold

East German lowlands

Since the current division of Saxony's natural area is not a simple further development or modification of the classification presented by Meynen, significant deviations have occurred, although some of the historical names have continued to be used and some of the demarcations have only been made more precise.

  • The main unit group level has been given up entirely. The newly introduced format of the “Saxon Natural Region” cannot simply be interpreted as a natural spatial unit, as it is only partially based on the boundaries of natural areas.
    • The low mountain ranges were summarized under " Saxon highlands and low mountain ranges ". These include the three older main unit groups D15-D17 and 41-43 plus in main unit 441 the more montane part of Upper Lusatia (D14 and 44).
    • The Oberlausitz was, except for the main unit 441 (s. O.), And in Saxon Lössgefilde , which would otherwise result from Erzgebirgsvorland and Saxon hills is (main unit group 19 and 45-46), incorporated.
    • The main unit groups Elbe-Mulde-Tiefland (D10 and 88) and Oberlausitzer Heideland (D10 and 89) were combined with the Saxon parts of the main unit group Lausitz Basin and Spreewald under Saxon-Niederlausitzer Heideland .
  • The level of the macrogeochore is still comparable to that of a Meynen main unit , but the layout of the individual units has been changed.
    • The division of the Erzgebirge was changed.
    • The Elstergebirge , formerly part of the Vogtland, appears in the rank of a macrogeochore, although when viewed across borders it only represents a part of such.
    • Numerous natural boundaries have been shifted or made more precise.
