摘要： To rationally adjust the energy flow path, direction and nutrient input of animal husbandry ecosystem, improve the output of animal husbandry ecosystem, promote the virtuous cycle of animal husbandry ecosystem and create a sustainable development animal husbandry ecosystem. On the research methods used in this article is system energy flow of interdisciplinary research methods, the integrated use of ecology, computer science, geographic information system, such as subject, in a wide range of basic research has been carried out for, production status in selected case of region analysis on two aspects of theory and practice research, analyses the energy flow path problems in animal husbandry ecosystem, energy production and energy conversion efficiency of energy flow characteristics, puts forward the fruit grain breeding in composite production mode, animal husbandry sustainable development countermeasure. In this animal husbandry ecosystem, the total energy output accounted for 49.43% of the total energy input in 2017, among which, the energy output from livestock products and livestock bodies accounted for 17.18% of the total energy input, and the output to the system accounted for 2.96%. In 2018, the total energy output accounted for 50.28% of the total energy input, among which, the energy output from livestock products and livestock bodies accounted for 17.65% of the total energy input, and the energy output outside the system accounted for 3.77%. The method of energy flow in animal husbandry ecosystem is an open ecological system. The system has higher ecological efficiency and economic benefits, less dependence on the outside world and good stability.
