The main condition for specialization in agriculture is the production of those products for which there is the most favorable natural environment. The purpose of our study is to determine the nature of territorial specialization in grain production based on the level and its dynamics. The object of the research is the agriculture of the Republic of Bashkortostan, which is one of the leading in the Russian Federation. The subject of the research is the factors of formation of territorial specialization of grain production. The work was carried out on the basis of the application of general scientific research methods within the framework of comparative, logical, statistical analysis and graphic interpretation of the results. The territory of the Republic of Bashkortostan is divided according to the complex of natural conditions, respectively, and according to the peculiarities of agriculture, into six zones. We have grouped municipal districts according to the volume of grain production in statics and in dynamics. A map of the municipal districts of the Republic of Bashkortostan for the production of grain by agricultural zones has been built. It was revealed that the dynamics of grain production in the republic has a multidirectional character. In terms of grain production, many regions of the region are promising territories, which, despite the low volume of production, are characterized by positive dynamics, as well as stagnant territories, which are characterized, despite the high volume of production, by negative dynamics. Areas in which grain production is higher than the average for the region are located in agricultural zones belonging to the Southern forest-steppe, the Ural steppe, and the Trans-Ural steppe. But at the same time, in many areas of the Cis-Ural and Trans-Ural steppe, grain production is also increasing, many of them have grain-growing specialization. In the regions located in the southern forest-steppe, grain production is below the average level in the republic, sunflower is most of all cultivated. Agriculture in the republic must be developed in the direction of creating specialized zones, which will allow lower costs to ensure the growth of production. At the same time, the organizational and economic mechanism must change in such a way as to stimulate the specialization and concentration of production.

This article reflects the construction of tourist cities using the resources available on the territory of Uzbekistan. The benefits of utilisation for the development of tourism infrastructure from geological cities that are not exploited, included in the available resources, have been analyzed. The high level of efficiency in the use of geological cities is based on the availability of economic infrastructure, which is recognized as the application of this infrastructure in the construction of tourist cities is low in costs. The article shows the specific natural anchors of three ecotouristic objects, the srategic plans for effective use of these anchors. Proposals on the expediency of the establishment of camps, bags, summer recreation zones are included in these facilities. The abundance of excursion facilities and attractions in the objects of ecotourism expressed their views on the possibility of opening remarkable travel destinations. And the steep slopes of the mountain are shown to be a special training area for training highly qualified climbers. Reflecting the peculiarities of the nature of the objects of the ecosystem, the role of these settlements with unique natural conditions in the development of tourism is established. The potential for the construction of such ecotouristic cities in the Republic of Uzbekistan is high, and the growth in the efficiency of the use of such potentials is reported to increase the number of tourists coming from foreign countries to Uzbekistan.

The results of the study of biomorphological features of species of the family Haloragaceae are presented. The Haloragaceae family includes 9 genera and about 130 species. Their distribution in natural conditions is discussed. Introduced family members are represented by three genera and six species. By its biomorphological feature they are perennial, rarely annual coastal-aquatic, marshy, aquatic, herbaceous plants. The life form – aerohydatophytes, hemicryptophytes. Native species of the genus Myriophyllum live in fresh, slow-flowing, almost stagnant reservoirs, and several species reach the coastal habitats. They are very sensitive to water temperature and less to light. The most common type of pollination is anemophily (with wind), entomophily (insect pollination) and autogamy (self-pollination) are also observed (very rare). There are individual populations that have the entire sterile flowers. For the members of the genus vegetative reproductions – with stems and turions, are peculiar. There is a clear correlation between the generative and vegetative reproduction of representatives of the genus Myriophyllum, which is related to the peculiarity of reproduction, the less seeds are formed in plants, the more turions are formed. When growing the representatives of the genus Myriophyllum, it is impossible to plant them at the depth at once. First they are kept in flooded areas of the shore, then, gradually, transferred to deeper sections of the reservoir. Myriophyllum thicket play a very important role in the life of freshwater reservoirs: they have the largest concentration of small invertebrates, which are the main food for the inhabitants of the reservoir, fish deposit the eggs on leaves, and later the fry hide there. Plants of the genus Myriophyllum have important fodder value, they are collected for fattening the waterbirds and fish, and also used as silage. The possibilities of their use in the conditions of introduction of open and protected soil are presented. Care and breeding methods have been developed in the moderate zone of Ukraine. Key words: Haloragaceae, range, introduction, biomorphological features.

Spatial-demographic distribution of population in the Republic of Srpska reflects the long-term historic, political, economic, settlement and demographic factors which determine the population distribution along with the natural conditions and modern determinants of social-economic development. The mutual impact of these factors caused the spatial-demographic polarization and irregular population distribution within the Republic of Srpskageospace. The population is mostly concentrated at low altitudes, in urban centers and areas with high-quality traffic connections.In contrast with these areas, there is an extensive process of depopulation in rural settlements, highland regions and areas along the entity borderline with BiH Federation.

Iron Ore Deposit

An adaptive economic framework is being designed within the framework of an ecological-economic zone with specified properties in the mountains of the Kabardino-Balkarian Republic (KBR), designed by the authors. Among the tasks in this direction is the search and assessment of functionally unencumbered natural conditions and resources of the region. Among the reserves not involved in economic activity, an important place is occupied by the Malkinskoe deposit of naturally alloyed iron ores. The purpose of the study is to probe the relevance of the issue for management structures and business, a preliminary assessment of the possibility of embedding the considered field in the constructed economic framework of the republic. In accordance with the designated goal, the following tasks have been set: - study of archival materials from Giprozem on the iron ore deposit for the purpose of realizing its technical and economic potential in relation to the conditions of modern market realities; - conducting field geophysical studies to test the author's hypothesis about a larger area of distribution of the serpentinite massif; - clarification of the mineralogical form of nickel in the ore and the identification of regularities in the distribution of alloying impurities in the open part of the ore strata; - assessment of the current intensity of contact of exposed ore layers with mountain streams.
