Keywords: old industrial region, geoecological situation, multidimensional sign space, sociogeosystem, environment

Abstract

The generalized statistical data on changes in the indexes of statistical parameters of the investigated process in time and on sociogeosystems is calculated and given. According to the results of the analysis of the dynamics of the indexes of the statistical parameters of the development of the geoecological situation in urban and district sociogeosystems, it has been established that for the entire study period (2013- 2017) the largest number of positive changes (growth) of parameters was noted for the cities of Pavlograd, Novomoskovsk and Sinelnikove. The largest number of negative changes (diminishing) of parameters was noted for the cities of Dnipro, Vilnogirsk, Nikopol and Kam’yanske. These data characterize the stability of the dynamics of the geoecological situation in cities. It was determined that the district sociogeosystems are even more differentiated by changing the indices of statistical parameters of thedevelopment of the geoecological situation in comparison with the urban ones. More positive changes are characteristic for Novomoskovsk, Krynichansky, Mezhivskyy, Shirokivsky and Vasylkivsky districts; the majority of the negative - forApostolivsky, Pavlogradsky, Petropavlivsky, Pyatihatsky and Yurievsky districts. The statistical analysis of changes in the indexes in the context of the calculation periods gave reason to assert the existence of rather complex and contradictory time patterns of the development of the geoecological situation in the district sociogeosystems, but in the vast majority of cases they coincide with the results of modeling the trajectory of the process. The analysis of changes in the indices of statistical parameters of the geoecological situation for each city and district sociogeosystem has allowed us to group the parameters by the frequency of positive and negative changes. The classification of the development of the geoecological situation in the sociogeosystems is carried out on the criterion of the sum of codes of changes in the indexes of statistical parameters. The calculated sum of the codes of changes of the indexes of parameters for each sociogeosystemmakes it possibleto purposefully manage the process of formation and development of the geoecological situation in the sociogeosystems. A similar analysis was carried out for all parameters of the development of the geoecological situation, which showed that according to the dynamics of the indices, they differ significantly for cities and districts.
