For implementation of economic activity the mankind long since used natural materials and various types of energy which are united in the concept "natural resources". This term has dual character. By drawing up classification the natural origin of resources, and with another – their importance in terms of economic exploitation is considered, on the one hand.
Classification of resources in terms of their origin
Traditionally carry to the resources including natural components climatic, mineral, water, land, soil, vegetable and also fauna resources. Separately experts consider resource base of natural and territorial complexes, for example, water - and forestry and landscape, mining and so on.
Any kinds of natural resources are formed usually within a certain component of a landscape. Formation of resources is influenced by the same factors that create a natural component. It is necessary to consider that the concept "resources" includes not only material objects and bodies, but also natural phenomena.
Classification of resources on the basis of exhaustibility
Resources of the planet are huge, but nevertheless are limited. In this regard classification of natural resources in terms of their exhaustibility is widely used. Refer energy of the seas and oceans to inexhaustible, winds, the sun and also climatic factors. Exhaustible resources subdivide into renewable and not renewable. It is possible to refer water, the soil, forests to category of renewable resources. However a vozobnovimost – a concept conditional as there are certain borders behind which resources lose ability independently to be restored. The majority of mineral resources belong to the category of not renewable.
Natural resources in terms of their economic value
The main category which is marked out by consideration of resources from a position of their economic use are resources of industrial production. They, in turn, are divided into power and not power. In classification the resources finding application in agriculture stand alone. Resources of industrial production include any kinds of natural raw materials which can be used in the industry in the structure. Especially energy resources are important for production: coal, oil, gas, nuclear fuel and also water resources, for example, energy of the falling water or sea inflows. Agricultural resources, in turn, are subdivided into agroclimatic, soil and land, vegetable and water. Warmly, natural moisture and the soil are necessary for cultivation of plants and a pasture of the cattle. Without water it is also impossible to support activity of crops and to breed animals. In droughty regions of the planet where reserves of natural moisture are small, artificial irrigation of lands is quite often used.
