Geomorphic Assessment Of Terrestrial Resources

摘要

Building of scientific basis for harmonious exploitation and spatial organization of the economy (land use) is one of the key issues of present-day geography. The study of land resources includes consideration of the relations between economic development, profitability and potential opportunities for further development of the territory, possibility of disturbed lands recovery and returning to the economic turnover, and preservation – all of those things which are necessary for human life worth living. Identification and analysis of land use types and forms is a necessary step of any economic-and-geographic study of a certain territory on the basis of statistical data and field survey. The creation of optimal land use schemes, taking into account the assessment of the conditions for certain types of management placement in given territory, has practical importance.Geomorphic assessment of territorial resources is based on the theoretical concepts of the anthropogenic-and-geomorphic system as a special morpholithodynamic system consisting of natural and anthropogenic components (mineral and biological) that are interrelated not only by natural flows of matter, energy and information, but also by the structures of socio-technical management.The problem of land valuation is particular important in old-cultivated areas, as it requires solutions to ensure rational use of territorial resources, with the greatest effect for the economy and with the least harm for nature, and preservation of the engineering, ecological and historical-and-cultural potential of the territories.A “second nature” is formed on the urban territory with its own microclimate, vegetation, relief and soils, surface water and groundwater, and, what is highly important, with the elements of management. Both natural and natural-and-anthropogenic geosystems operation modeling, as well as the forecasting, is the basis for the territorial resources and natural-and-anthropogenic risks management.This paper presents the logical model of the area natural conditions influence on the evolution of urban land, shows the ways of creating the model of comfortable environment, where all types of the place attractiveness – ecological, social and economic – should be balanced.A constructive formula for the geomorphic assessment of territorial resources includes the synthesis of benefit and profit. That is an engineering and ecologic-and-geomorphic assessment of lands in terms of the convenience for some sort of economic activity, taking?into account the ecologic-and-geomorphic restrictions, as well as the economic evaluation of the engineering site preparation, taking into account the availability of recreational and specially protected areas, as well as environmental insurance against adverse processes and phenomena – maintaining of favorable living conditions.
