The article is devoted to improvement of the method of assessing of the environmental sustainability of agricultural land use in the territorial structure of the region. Approbation of this method was carried out on the example of the districts of Lviv region. An assessment of the environmental sustainability of agricultural land use was made on the example of the districts of Lviv oblast. To determine the ecological norms of the level of land use stability in the territorial structure, S. Volkov's methodology was applied taking into account the specificity of the landscape structure of the territory of Ukraine. The author os the work has measured the coefficient of environmental sustainability of the Lviv region with consideration of some factors of ecological stability for various types of agricultural and other lands. It is proposed to specify the coefficients of environmental sustainability of land use for three types of territories. The expediency of that method use for determining of the coefficient of environmental sustainability of certain territories is established in the research. It is not reasonable to carry out the similar measuring on a small territory (agricultural enterprise, village council), whereas іt is the best to count on it for the district. The article supplies analysis of ecological parameters and the modern structure of the land area in Lviv region. According to the analysis of the coefficient of ecological sustainability of agricultral land use, there are three distinguished groups of districts depending that factor level, particularly stable, medium stable, low stable. The medium and low level of stability are caused by human impact on the nature, causing transformation of environmental land into the open land with a low level of stability. The assessment of the ecological stability of land use in the territorial structure of the region confirms the dilemma of an alternative choice of economic development of the agrarian sector or conservation of the natural environment.
