【 摘 要 】

In the paper the study's results of energy-based measuring of ecological and economic effectiveness of agroecosystems are given. The principles and provisions of the methodology of geosystems self-organization are presented, the short algorithm of energy analysis of geosystems is proposed. The results of agroecosystems energy evaluation in different climatic conditions are shown, that allows assessing and comparing the energy efficiency of natural-climatic and economic resources. In particular, based on analysis of energy efficiency of functioning of farm Tomsk region the flow-oriented model of the agroecosystem as operationally closed structure has been developed. Under the proposed methodology some calculations carried out. With use science-based and rational-based management system optimization of energy costs in the AGES of the Tomsk region can be reduced. Based on analysis of energy efficiency of functioning of agro-ecosystems of a steppe zone of Kazakhstan practical results have been obtained. For the steppe zone of Kazakhstan the natural savings of energy generated through precipitation has been defined. The most real value of organic fertilizer to maintain the fertility of dark chestnut soils in the energy measurement is assessed. The energy efficiency of biogas technology implementation in the functioning of the economy based on the use of organic waste of agriculture with the simultaneous production of organo-mineral fertilizers have been showed. The use of energy assessment, in combination with economic, objectively reflects the essence of the ongoing social-economic processes and reveals the true labor costs of production. The most promising is the transition to managing agro-ecosystems as complex self-organizing structure working on the principles of operational introversion. The challenges for further research are set.
