The thesis is devoted to elaboration of methodological, methodic and organizational principles for the comprehensive statistical assessment of ecological effects from the agricultural operation of enterprises. Main factors are justified, and sectoral components of the mechanism for constructing statistical assessment of ecological effects from the agricultural operation of enterprises are defined. The meaning, methodological and organizational principles of ecological effects caused by agricultural operation of enterprise are defined. Methodological problems in the field of statistical recording of the emission of dangerous substances from stationary sources of the agricultural sector are studied. An algorithm for computation of the emission of dangerous substances from home animals breeding is constructed and used to compute the emissions of ammonia and methane, nitrogen oxide and non-methane light organic compounds from home animals breeding. A qualitatively new direction for solving a vital scientific problem is proposed by theoretical generalization of international and domestic practices: the methodology for statistical assessment of the operation of agricultural enterprises and its ecological effects It is demonstrated that the scientific justification of ecological effects from the agricultural operation of enterprises as an object of a statistical study depends on the performance of plant-growing and animal husbandry sectors. The notion of "ecological effects caused by the agricultural operation of an enterprise" is introduced in the scientific use on the basis of a critical review of scientific approaches to the interpretation of agricultural operation and various aspects of its development. A set of indicators of ecological effects caused by the operation of agricultural enterprises is constructed, which will enable to improve the directions of the statistical assessment of antropogenous impact of the agricultural sector on the environment. The need for solving long-term and current strategic problems related with preservation of the environment in Ukraine called for elaborating standard conceptual approaches to their assessment. The thesis presents a phased conceptual scheme for the assessment of ecological effects from the operation of agricultural enterprises, constructed by the author as the basis for elaborating and performing ecological monitoring, and implementing the balanced agrarian policy in the country. It is demonstrated that the scientific justification of ecological effects from the agricultural operation of enterprises as an object of a statistical study depends on the performance of plant-growing and animal husbandry sectors. A set of statistical indicators is constructed, intended for the qualitative assessment of ecological effects from the agricultural operation of animal husbandry sector. A sound assessment of ecological effects by sector of agricultural production is the fundament for elaborating measures of the effective ecological policy. The main methodological principles for the statistical assessment of ecological effects from the operation of agricultural enterprises must include complexity, national specifics, and consistency. The information support must be adequate to main directions of regulation of national processes, to enable for accurate reporting of indicators in the system of natural-economic recording. A central objective in creating the primary information area is to assure completeness and objectivity of data on ecological statistics and improve statistical recording and observations; a main component of needs of users of ecological statistics is, therefore, an adequate coverage of respondents by statistical observations and ecological management of activities involved in environmental protection, which will have essential impact on the improvement of ecological situation in Ukraine. The reasonability of the use of ranking of Ukraine's regions by indicators of ecological effects from agricultural operation of enterprises, elaboration and implementation of effective programs for normative regulation of the scopes of ecological effects from the operation of agricultural enterprises in regions and the respective support of agricultural enterprises is proposed and scientifically justified. The proposed methodology enabled to perform a comprehensive statistical analysis of ecological effects from the operation of agricultural enterprises in the regional dimension, to group homogenous regional zones, to define "problematic" sectoral areas of production (plant-growing, animal husbandry). Results of the proposed approach, if applied by the core user of statistical information, the government, will help elaborate and implement measures for mitigating ecological effects in the grouped homogenous territories, develop ecological-economic relations, and improve the mechanisms for government support of agricultural enterprises. Statistical questionnaires for a sample survey are developed and used as a supplementary source of data for the statistical assessment of ecological effects from the operation of agricultural enterprises; they are used for the computation of the technogenous burden on the air by stationary sources of pollution in the animal husbandry sector, emissions of methane and ammonia in particular. The method for assessment of the emissions of dangerous substances from home animals breeding enables for improving the system of ecological-economic assessment of ecological effects from business operation, existing in Ukraine.
