Information and analytical system “Ecology of agrobiocenoses”

Abstract

The study of mechanisms of formation and patterns of interaction of individual components of agrobiocenoses involves the processing of large arrays of heterogeneous geographically distributed data obtained at different times and in different soil and climatic conditions. In this regard, we have begun the development of an information-analytical system and related software that will allow us to accumulate, store and conduct a consolidated analysis of unrelated data regarding long-term monitoring of agrobiocenoses and surrounding ecosystems. The general scheme of the information-analytical system “Ecology of agrobiocenoses” and its interaction with the means of remote sensing of the Earth and the capabilities of GIS technologies has been formed. Based on free software, cloud computing systems, the elements of a web-oriented information system have been developed to create databases characterizing the leading abiotic, biotic, technological aspects of agrobiocenoses. A relational database model has been formed that allows the collection, storage and consolidation of entered information. Modules have been developed to collect the main characteristics of resource-saving technologies for crop cultivation, as well as the impact of winter wheat harvesting methods on combine harvester productivity and yield. The practical example shows that the analysis of a wide range of heterogeneous information in combination with GIS technologies which give a clear spatio-temporal localization of objects makes it possible to identify patterns of interaction between the components of agrobiocenoses, which at first glance are not related to each other. The data of technological field experiments and separately conducted observations of avifauna and mouse-like rodents were studied. It was established that the forage base of birds and the highest population density of rodents coincide geographically with cultivation using direct sowing technology, which caused a significant loss of winter wheat in the autumn-winter period in these areas
