To preserve and increase the biological and landscape diversity, it is necessary to have comprehensive information about the conditions and dynamics of changes in the study object, a specific local ecosystem. Nature reserves are created to restore habitats, to protect endangered species of flora and fauna, vulnerable or complex species. Particular attention should be paid to the study of wetlands, a stabilizer of the hydrological regime of ecosystems, and a shaping element of the regional climate. It is proposed to involve remote sensing and Earth observation methods to address studying issues of the conditions of the wetlands. Space images are used to monitor, inventory, and map natural resources, observe seasonal and perennial changes in the natural environment, and assess the impact of anthropogenic activities on the natural environment. The calculation of spectral index was used to analyze the dynamics conditions of the plant communities and moisture supply on the Beloozersk section territory in Rivne Nature Reserve. It is proposed to use information-analytical technologies and data processing to study dynamic changes in the conditions of wetlands. ArcGis tools are used to collect, collect, process, formalize and present data on influencing factors and the shape of the ecological ecosystem. Such studies can be the basis for creating a system for monitoring the condition of vegetation and its moisture supply in the study areas. [ABSTRACT FROM AUTHOR]

The article presents methodological approaches to the improvement of the environmental monitoring system. To increase the objectivity and to improve the visual aspects of data presentation during ecological monitoring, the authors proposed to involve remote sensing methods of the Earth and geoinformation technologies. The presented set of methods is effectively used for general, operational and background monitoring. The authors have developed an algorithm for monitoring the state of ecosystem components by remote sensing methods. The method of detection and recognition of technogenic-hazardous objects on the example of a solid waste landfill for the assessment and analysis of risks of environmental components pollution is proposed. It is suggested to use information-analytical technologies of data processing for conducting research of the dynamics of changes in the condition of the studied territories. Retrospective maps of the biotopes of the nature reserve are constructed and the types of biotopes specific to the studied territory are identified. The changes that occurred in the distribution of biotope types in the territory of the nature reserve were evaluated.The article presents the results of graphical data analysis on electronic maps, which are presented in the form of Ecological map of the region. The elaborated ecological mapping models are the basis for evaluation of environmental status of the studied territory and compiling a set of digital thematic maps in the GIS environment. In addition to visualization, this model allows to predict the possible contamination and outline the area of influence. Synthesized interactive mapping models can be updated with continued use by conservation organizations or interested users. [ABSTRACT FROM AUTHOR]
