Особенности теплового поля города Ростова-на-Дону по данным дистанционного зондирования Земли

Abstract

Thermal fields of natural and anthropotechnogenic origin are an integral part of the urban habitat, which influences the functioning of its components, as well as determines the conditions of existence of living organisms including humans. Settlements act as areas of formation of extensive temperature anomalies, mainly positive ones, known as urban heat island. This phenomenon was discovered more than 200 years ago and is currently being investigated in detail. However, the study of smaller anomalies - neighbourhood-scaled and local - is also a subject of scientific and practical interest. These heterogeneities in the distribution of thermal energy are caused by the presence or functioning of individual objects, and therefore, on the one hand, have a direct impact on the state of the environment and human living conditions, and on the other hand, are a promising area for the development of environmental engineering and settlement rational arrangement. As part of the conducted research, the main patterns of spatial distribution of the Earth's surface temperature within the Rostov-on-Don city district were identified, as well as the areas of formation of anomalies of local and neighbourhood scale and objects and processes contributing to their formation were identified. The results and conclusions can be used for further study of ecological and geophysical features of urban landscapes, and also have an applied value in determining the direction and consequences of the impact of the advancement of specific types of urban development of the territory.
