Risk management of a development of systems and territories is one of the key problems of managerial decision-making. This is due to the impossibility of carrying out model experiments and the complexity of formalization of characteristics. The necessity of considering the peculiarities of the spatial distribution of subjects and objects of management allows to speak about relevance of geoinformation management. Compared with other classes of potentially hazardous systems, spatially distributed systems and areas characterized by a significant level of inertia that contributes to sustainability in development, but hinders the development management and allows the dynamics to determine the influence of threat factors. The effects of hazards on the territory are systemic. The article describes: - analysis of dynamics of control conditions for the development of spatially distributed objects and territories; - classification of risks for coastal management; - principles of risk management development of the coastal areas; - the system model (conceptual model) of risk management in its spatial aspect, as well as private models for risk management under the influence of natural factors.

The article considers the problems of functioning and development of complex socio-economic systems of coastal areas in unstable weather-climatic conditions. It is known that the characteristics of the spatial organization of economy of coastal zones are defined industrial and trade specialization and tourism potential of the area It is shown that socio-economic systems are subject to a number of factors, including weather and climatic conditions, which can have both positive and negative effects on economic potential. development of the coastal areas. The density distribution and the economic activities should be considered. The classification of risks of socio - economic systems of coastal areas, due to the influence of hydrometeorological conditions are described. The need to incorporate the tasks of risk management function and the development of spatial distributed systems in the concept of integrated coastal zone management is justified. The model of management of hydrometeorological risks in the system "territory - economy - natural environment" in the space-time dimension is developed. Proposed methods of solving the problems of functioning and development of complex socio-economic systems are based on complex research carried out by the authors.
