Introduction.

The ecological situation is considered as a territorial combination of various, including negative and positive, from the point of view of habitation and the state of health of the population, natural conditions and factors that create a certain ecological situation on the territory of varying degrees of well-being and trouble.

Environmental problems – a negative change in the properties of landscapes, causing deterioration in living conditions and health of the population, depletion or loss of natural resources, violation of the gene pool (Kochurov)

Environmental problems – problems associated with the noticeable impacts of man on nature, the reverse effects of nature on man and his economy (Reimers)

Classification of the ecological situation

Depending on the purpose, the method of classification and classification features are determined.

As classification features, we single out the following: the cause of occurrence, complexity, the main changing component of nature, the time of occurrence, the time of manifestation, the rate of development, the place of occurrence, the scale, zoning, the form of manifestation, belonging, consequences, severity, the possibility of solving, the method of solving.

When classifying environmental problems and situations as objects of spatial analysis, the following principles are observed:

systemic – consideration of an object as a system of interrelated characteristics

genetic – analysis of the initial state of the phenomenon and the selection of subsequent states from it

anthropoecological – taking into account living conditions and the state of health of the population, preserving the gene pool

informational – fixation of stable features based on an empirical base

constructive – the choice of ways to harmonize the relationship between nature and society and approaches to solving environmental problems.

Classification features and characteristic environmental problems and situations

sign (criterion) problems and situations
cause of occurrence natural-conditioned, anthropogenic, including ecological-industrial, ecological-transport, ecological-residential, ecological-hydraulic, ecological-agricultural, ecological-pasture, ecological-agricultural, etc.
structure (complexity) of the situation simple, complex, very complex
basic changing component of nature atmospheric, water, soil, geological and geomorphological, biotic, complex
time of occurrence past, present, inherited; occurring almost simultaneously with exposure or at regular intervals
development time short-term, long-term, practically non-existent
development rate fast-paced, slow-paced, fast-paced
belonging to the territory local, cross-border, mixed
spatial coverage (scale) local, sublocal, regional, global
zoning zonal, non-zonal
manifestation form point, line, area
origin old-developed areas, areas of new development, rivers, reservoirs, mountains
effects anthropoecological, natural resource, landscape genetic, economic, political, legal, etc.
sharpness very spicy, spicy, moderately spicy
decision possibility solvable, intractable, practically unsolvable
decision priority priority, non-priority
solutions organizational, economic, technical, legal, etc.

Consider some of the positions identified by the above features.

Environmental problems associated with the violation of individual components of the landscape or their complex can be divided into six groups:

atmospheric (atmospheric pollution: radiological, chemical, mechanical, thermal);

water (depletion and pollution of surface and groundwater, pollution of seas and oceans);

geological and geomorphological (intensification of unfavorable geological and geomorphological processes, disturbance of the relief and geological structure);

soil (pollution, erosion, deflation, secondary salinization, waterlogging, etc.);

biotic (vegetation reduction, forest degradation, pasture digression, reduction of species diversity, etc.);

complex, or landscape (desertification, biodiversity reduction, violation of the regime of protected areas, etc.)

Since we define an ecological problem by changing the properties of landscapes, the degree of its manifestation can be characterized in terms of the intensity and area of distribution of these changes and the nature of the consequences. It is conditionally possible to distinguish three degrees of distribution of natural properties – signs of individual problems:

Weak (change in the natural properties of the landscape by less than 10%) Medium (from 10 to 50%) Strong (more than 50%)

There are three main groups of problems and situations according to the environmental consequences of changing nature:

anthropoecological – to change the living conditions and health of the population;

natural resource associated with the depletion and loss of natural resources, worsening economic activity in the territory;

landscape-genetic, caused by the violation of the integrity of landscapes, the loss of the gene pool, the loss of unique natural objects, etc.

In this regard, there are three main types of environmental situation assessment system:

assessment of the quality of the natural environment for human health, including analysis of environmental hazards;

assessment of anthropogenic impacts and loads;

assessment of negative changes in the environment.
