**Abstract:**

The state of the environment is an integral, key component of the generalized category of the quality of life of the population. In this regard, there is an objective need to develop methods and tools designed to implement a system of continuous monitoring of the key environmental indicators and forecasting the occurrence of abnormal states of ecosystems. In this paper, we consider an approach to multivariate classification of the states of natural and technical objects and systems, based on the development of methods for dynamic detection of anomalies in information data flows. The approach is based on an estimate of the statistical discrepancy between the probability distributions of random variables over variably variable time intervals, as well as an estimate of the probabilities of errors of the first and second kind.

The structure of a multichannel software and measurement complex for detecting anomalous states of natural-technical objects and natural-technical systems is proposed, and the results of model calculations are presented. It is assumed that it is possible to initially form reference versions of the states of natural-technical objects and natural-technical systems based, for example, on expert assessments or a priori information. The use of a multivariate approach allows you to optimize the processing, analysis, and integration of heterogeneous data. The results of the study confirm the stability and sensitivity of the method when selecting threshold values of intervals that determine the states of objects.

This model can be used in other subject areas where the assessment of the dynamic parameters of controlled objects is required, for example, when detecting vulnerabilities in the interfaces of unmanned vehicles in the infrastructure of a smart city.
