The problem of providing the sustainable development is aimed at the harmonizing of social, economic and environmental spheres of social development. The purpose of the article is to substantiate methodological approaches to ecologization of spatial development in Ukraine at the present stage of state formation, which is characterized by strengthening of the decentralization authority processes. The article takes into account the new rate of reasonable and balanced growth and proves approaches to the assessment of ecological processes of the region’s development. In the conditions of the decentralization of the social systems’ management processes, the importance of the trajectory of sustainable development of territorial communities and other taxonomic units has been updated. The methodology for the territorial community’s development in the conditions of institutional changes has been approved. The current practice shows that at the level of the territorial communities the parameters of their sustainability are not calculated or analyzed, though, in the conditions of the management processes decentralization it is significantly important. In the field of environmental protection it is expedient to introduce monitoring of the settlements pollution level and to strengthen the control of human waste management. For the comprehensive assessment of the territorial community’s development we propose to use such a criterion for evaluation as a sub-regional upgrade index. The base for the index could be statistical information, which is formed by the classical method of surveys. It could become a marker of the investment attractiveness of a particular territorial community and the task for the executive power and local government to take measures for the integrated and balanced development of all taxonomic units of the state. Effective regional development management is the significant factor of the productive forces modernization of the whole state, especially in the conditions of intensified globalization and integration processes. Under these circumstances ecologization problems deserve special attention. Political direction on the authority decentralization demands increased attention from the local authority to the environmental management and environmental protection.
