Abstract
The Black Sea estuaries are unique natural formations that are important objects for the inhabitants of the region. They have a significant impact on their life, health and well-being. However, today the ecological conditions of these estuaries are critical, which requires systematic monitoring studies based on geoecosystem methodology. The presented research identify some features of the state of geological and ecological subsystems of estuaries geoecological systems and their surrounding, outline the main factors of violation of the state of the elements of estuarine geoecosystems. In order to preserve the natural value of the estuaries, the main principles and approaches to comprehensive geo-ecosystem studies of these natural objects have been proposed. The application of the proposed approaches assumes that the geoecosystem of estuaries is multistable; it features the dynamic transition zone between the sea and the continent (geoecoton) and requires specialized methods to analyze its past and present state and predict the future changes. The structure of this system is space-time related. The spatial aspect reflects the order of elements in the system, time aspect corresponds to the changing in the system during the period of time and its dynamic. The ecosystem of estuaries is affected by significant natural and anthropogenic stresses and characterized by the pollutions of heavy metals.
