Geography in the Republics of Central Asia

A review of the last 50 years of geographic research in the four Central Asian republics of Uzbekistan, Kirghizia, Tadzhikistan, and Turkmenia, where the dominant desert and mountain landscapes impose a specific character on geographic investigations. Physical geography has tended to focus on glaciation in mountains and on surface runoff in the desert as potential sources of water for irrigation. Economic geography has emphasized the utilization of desert pastures.     

Some Prerequisites for Calculations of an Economic Land Evaluation

An indicator relating crop yields to labor and capital inputs is suggested as a measure of the relative natural fertility of land, and thus as a criterion for economic land evaluation. For mathematical convenience, crops are reduced to a standard product, and the cost of producing a unit of standard product is then taken as the basic criterion of natural soil fertility.     

Zones of Influence of Middle-Size Cities,Their Boundaries and Passenger Flows

A modified gravity model is used to describe the flows of commuters between a central city and concentric zones around it. A multiplier-type model of a central-place system (after Christaller) is then used to calculate the number of residents for service centers at each level of the hierarchy within the system. The rank-size rule (Zipf's formula) is also considered as a criterion of a true system of urban places. Results are presented for the urban network of the Ukraine.     

An Evaluation of the Territory of Moscow Oblast in Terms of Physiologic-Climatic Parameters

A regionalization of Moscow Oblast is derived from a physiologic-climatic evaluation for purposes of settlement and recreation. The evaluation is based on the frequency of occurrence of particular classes of weather through the year. The most common classes in Moscow Oblast are the 1C class (light negative heat balance), which is determined by global macrofactors and produces an undifferentiated background in the oblast, and the N class (comfortable condition of heat equilibrium) and 2C class (moderately negative heat balance), which reflect more localized factors and can be used for a differentiated evaluation of physiologic-climatic conditions. Eleven physiologic-climatic regions are delimited on the basis of the difference between the number of days with comfortable conditions (N class) and the number of moderately cold days (2C class). Optimal conditions for settlement and recreation are found south and southeast of Moscow; the most unfavorable in the low-lying swampy Dubna area, where the Moscow-Volga canal meets the Volga River.     

COTTAGE SETTLEMENTS AND GARDEN COOPERATIVES IN THE MOSCOW AREA

Spaee-time shifts are analyzed for a particular type of suburban recreational, development—the cottage, settlements and garden cooperatives around Moscow. Measurement of the appearance, stabilization and decline of this recreational function along six major rail lines radiating from Moscow shows a centrifugal shift fostefed by the development of high-speed transportation and the conversion of older recreational areas close to the city to residential and industrial uses. A characteristic feature of the expansion of the recreational zone Over time has been a leaping movement in which the centers of recreational development, after having taken shape for one or two decades, will suddenly leap outward to a more distant zone. Furthermore, suburban cities are beginning to generate their own demand for recreational space and are becoming nuclei of their own recreational zones.     

THE GEOGRAPHY OF OCEANS AND ITS BASIC PROBLEMS

The study of oceans as a subfield of geography has gained acceptance in the Soviet Union. Some universities have introduced courses in marine geography, and geographers have participated in oceanographic research voyages. An effort is made here to define the place of a marine geography within the geographic discipline as a whole, to set the spatial limits for geographical investigations of the oceans and to suggest problem areas suitable for geographical analysis. In keeping with the Soviet dichotomy, physical and economic geographic problems are distinguished. Physical-geographic problem areas would include study of oceanic water masses; large-scale interaction between oceans and atmosphere; study of island environments, and the biogeography of oceans. Economic geographic problems would focus both on theoretical aspects, such as spatial regularities in human activities related to oceans, and on applied aspects, providing a sound basis for economic development of ocean areas.     

Techniques for the Recreational Evaluation of an Area

Because of the problem of factor weights in any integral evaluation of landscapes for recreational purposes, a systems approach is proposed for classifying factors in terms of relative significance. Internal and external landscape structures are distinguished. Internal structure involves the organization of the landscape, including components and their natural interactions. External structure reflects the landscape system's relations with other systems, either adjacent landscapes or systems of human activities. For purposes of recreational evaluation, landscape elements must be differentiated into classes in terms of their impact on recreation: active elements, favoring particular recreational uses; limiting elements; compensatory elements. The state of recreational resources must also take account of current economic use of the land. Some types of economic uses combine more readily with recreational uses than others. The systems technique is illustrated with reference to the Moscow region and the Issyk-Kul' basin in Central Asia.     

The Transport Industry in the West and East Zones of the USSR

The levels of development of production and transportation are compared for the western and eastern zones of the USSR. The low density of the transport net in the East, combined with the high cost of transport construction and a manpower shortage, tends to favor the development of large industrial complexes within limited areas making use of the zone's unique natural resource base. Such areally concentrated development would reduce the need for local transport systems and make more investment available for the more efficient mainline routes. The western zone, with its virtually continuous economic development and denser transport net, favors a more uniform location of production and the increasing location of industry in small and middle-size cities, which would ease the load on heavily used mainline transport routes and make greater use of local forms of transportation, including motor freight.     

Marginal Cost Estimates of the Water Resources of the USSR

A water-management regionalization and determination of marginal cost estimates of water resources over the next three decades (to about 2000) outlines a set of priorities for the construction of dams and interbasin diversion projects. The predicted water requirements are based on the assumption that irrigation needs will increase at a moderate rate (30 million hectares by the end of the forecast period). The resulting marginal cost estimates are expected to affect long-term plans for the location of water-intensive activities (irrigation, water transport, thermal power generation, chemicals, pulp and paper) for which water costs may represent 40 to 50 percent of the total cost difference between alternate locations.     

CONTEMPORARY PROBLEMS IN THE CONSTRUCTIVE GEOGRAPHY OF LARGE CITIES

The increasing impact of urbanization on the natural environment and physical constraints on city planning in the various natural zones of the USSR call for a program of research that would bring to bear the tools of the various geographical disciplines on the problem and might give rise to a distinctive geography of city planning. Geomorphology might be concerned with a variety of caving and slumping processes typical of large cities; climatology with the impact of cities on the microclimate of an area; hydrology with watertable changes and water-management problems, and biogeography with the distinctive plant and animal life of large cities and urban agglomerations. More complex, integrated research in both physical and economic geography would deal with the choice of suitable sites for new cities, particularly in extreme types of environment; with predictive aspects of the impact of urbanization, and the functional structure of cities. A number of cities and parts of cities with different layouts and different environmental settings should be designated as experimental study areas for geographical research of a more systematic character.
