The present paper contains the evaluation of rural landscape development in model territories by means of landscape structure analysis. Based on the computed values of landscape ecology indexes, development and typical and specific features of analysed territories are interpreted in defined time horizons. The territories differ in the intensity of their use, natural conditions and different social requirements. Two territories have intensive agriculture in different natural conditions, the third model territory is situated in the protective zone of a water resource, and the fourth model territory is a protected area. For all localities, the studied baseline period was that of the Stable Cadastre mapping (1825-1839), followed by the sixties of the 20th century and the present time. The method of processing and evaluation of four model territories is described and a detailed analysis and interpretation of one territory - Hubenov region is presented. Agricultural land formed the landscape matrix in Hubenov territory in the past and at present. There is a significant reduction in the number of plots of the landscape classes and the increase in the average size of agricultural and non-agricultural plots between year 1825 and 2009. Spatial distribution of agricultural land has changed. Area of arable land decreased after the construction of water reservoir Hubenov. The area of permanent grassland, forests and water bodies increased. It was reflected in an increase of ecological stability. In the context of the change of landscape structures decreased the length of ecotone edges of the categories arable land and PGL and categories arable land and forest.
