摘要：Land use is one of the characteristics of landscape, which can be presented numerically as the structure of land use. On the basis of the assumptions of the relative deviations method, the changes of the land use structure in the Lublin voivodeship in the years 1995-2001 have been presented. The research was carried out in 213 basic units composing the area of the administrative region presented.
In each unit the proportion of individual elements of the land use structure in 1995 was compared with analogous figures from 2001, which gave information about changes. The intensity of these changes is illustrated with degrees of deviations which can be given a working name of degrees of changes or degrees of dynamism, calculated with the application of mathematical formulae
+n = (log kn - log p) / log 1.1
-n = (log kn - log p) / log 0.9
where:
n - degree of deviations;
kn - quantity of an element in 2001, expressed in percentage;
p - quantity of an element in 1995, expressed in percentage.
The results of calculations for individual elements of land use structure have been presented by means of the method of a superficial cartogram, employing the concept of twin complementary maps, one of which shows positive deviations and the other negative ones (Fig. 1-7).
Dynamism is attested both by the rise and fall of a value. Degrees of deviations for the arable land in a basic unit have been totalled as absolute values. In this way a synthetic indicator, attesting to the dynamism in this unit, has been obtained. This assumption has made it possible to construct a map of landscape dynamism from the point of view of the changes of land use (Fig. 8). An average arithmetical indicator of dynamism is 10.54. This value has been assumed as the limiting quantity between the area of a stable and dynamic landscape, regarding the area below average as stable and above average as dynamic.
The application of the old method in new conditions, when the data processing technique is no obstacle, has given interesting results, only part of which has been presented in this paper. However, it is an important part, presenting facts which provide the basis for some further detailed research, and especially for searching the causes of such a state of facts.
