Natural and historical aspects of the environmental monitoring in the city of Lviv

Purpose. To study the natural-historical aspects of the organization of monitoring the components of the natural environment in the territory of the city of Lviv, to identify the peculiarities of its organiza-tion at different historical stages of the functioning of the urban system, to highlight the specifics of the organization of environmental monitoring in modern conditions. Results Regular meteorological observations with the help of instruments began in Lviv in 1811, and observations and descriptions of the city's vegetation were carried out in the 1950s. Ya. Lagner. In 1944, the Department of Hydrometeorological Service of the Carpathian Military District was organized in Lviv. It included: weather bureau, group of hydrological forecasts, group of restoration of the network of stations. At the beginning of 1946, on the basis of this department, a hydrometeorological office was creat-ed, which since 1959 functioned as a hydrometeorological observatory (HMO) with groups: meteorologi-cal, hydrological forecasts and agrometeorological. In 1964, the Lviv Aerological Station became part of the GMO under the authority of the Aerology Department. Old, historical Lviv was located in the middle of large forests, had many streams, brooks, as well as rich flora. Such diversity is determined by the geo-graphical location, the history of the formation of the relief and climatic conditions in previous geological periods. The study of the landscape-natural primary basis in comparison with the built-up areas leads to the demarcation of the urban environment based on belonging to a certain type of natural landscape and thereby determines different approaches to its transformation. Background observation points located at nature conservation facilities provide information about the state and changes in the natural environment that occur outside of human activity. A comparative analysis of similar indicators obtained in areas with different degrees of urban influence will make it possible to reveal the real state of anthropogenic changes, identify their causes, predict the further consequences of urbanization, as well as build models of such social and production systems that would be the least harmful to the environment. Conclusions. Environmental monitoring in the territory of the city of Lviv has a long history. Moni-toring the state of the atmospheric air, water environment, biodiversity was and remains an important component in the issue of the quality of the urban environment and does not lose its importance. Environ-mental monitoring must be considered as an integral part of the regional management system of nature management, which must perform the target functions of continuous observation and forecasting of the main socio-ecological processes for the purpose of their analysis, identification and identification of the main factors for the preparation and adoption of management decisions.
