The essence and classification of tourist resources

3.2. Approaches to the classification of tourist resources .

There are several approaches to the classification of tourist resources. Of these, the classification proposed by the Polish economist M. Truasi (1963) and the French economist P. Deferem (1972) is much improved.
M.Truasi distinguishes three groups of tourist resources:

1. 
   Natural tourist resources, as ‘tourist capital potential’, include climate, air, landscape, sea, lakes, rivers, mountains, forests and more. In other words, these resources can be called natural-climatic resources .
   
2. 
   Man-made tourist resources, i.e. architectural buildings, monuments, cultural objects and so on. These are the objects of the tour.
   
3. 
   "Additional" tourist resources are enterprises created by human labor, which receive and serve all tourists in a particular region. Through these resources, it is possible to assess the level of service to tourists.
   

However, Russian experts MENemolyayeva and LFKhodorkov believe that the host and service enterprises can not be added to the tourist resources. Because these businesses are from available tourist resources
using, otherwise they will not be able to provide services covering the entire tourist trip.
Deferem divides all tourist resources into 4 groups: hydrom, phytom, lithom and

anthropom.

Hydrom - This includes water-related tourist resources. This group includes lakes, rivers, seaside, glaciers, mineral springs, hydroelectric power plants, waterfalls and more. Examples include the famous Niagara Falls, the Amazon River, and the seaside beaches of Spain.
Phytom is a natural tourist resource, the composition of which can be of two types: naturally created (forests, mountains, peaks, volcanoes, natural landscapes) and man-made (national parks, parks) .  
Litom is a man-made resource that attracts tourists by itself or by its characteristics, and includes architectural monuments, ancient human settlements, and open-air museums. In addition, lithoms include modern facilities: bridges, airports, sports complexes, universities, aquariums, observatories and more.
