Regional landscape-ecological studies have acquired a special topicality as efficient environmental conservation and rational use of natural and resource potential is a major prerequisite to sustainable development. Such studies are underpinned by collection, systematization and consequent arrangement of information on environmental components. Such an opportunity is provided by geographic information systems (GIS).A landscape-ecological analysis was performed based on 4 basic integral indices: 1. ecological potential, 2. ecological stability, 3. ecological load, 4. ecological tension.
The values of basic integral indices of the landscape-ecological analysis were calculated as sums of respective indices expressed in scores and multiplied by their significance reflecting coefficients. In agreement with that rule, a formula was derived of calculation of basic indices of landscape-ecological analysis (ecological potential, stability, load and tension). Subsequently, those factors were integrated by “Model Builder” in ArcGIS 9.2 applying “Weighted Sum” functions.
