Evaluation of technogenical load in urbanized territories on the example of Lithuanian cities

Evaluation of technogenical load in urbanized territories was carried out by segregating technogenical complexes of various character. In the majority of cases, different effects of different technogenical complexes are identical and recurrent. Moreover, impact zones of technogenical loads in a geological environment often overlap and make up the general influence zone. Therefore, the density of objects comprising a technogenical complex and their impact zones determine the intensity of technogenical load on a territory. On large territories containing technogenical complexes of various purposes, technogenical load intensity is measured accounting for various buildings and factories according to their size and the parametric indices of activity. Separate indices are pieced together into a general (total) resultant of total evaluation. Technogenical load maps, the primary aim of which is to reflect the integral external forces influencing the geological environment, were compiled employing this methodological principle. Analysis of technogenical load intensity allowed to evaluate the regularities of this load distribution on urban territories.
