Study On The Evolution And Development Of Regional Distribution Of Animal Husbandry In China

Since the reform and opening up,China's animal husbandry has been unprecedented development,not only promoted the rapid growth of the economy,but also gradually meet the growing material needs of the people,further improve the living standards of our residents.But our country is a large country,and from the reform and opening up to the present 40 years,each region of the resource situation,economic level,technical level and has a huge consumer demand change,under the influence of various factors,China's animal husbandry breeding area layout occurred to the north,to the low level of economic development of regions together trend,gradually replaced natural factors as economic factors livestock farming layout of the most important factors in our country.The evolution of regional layout of animal husbandry is not only in the past,but also in the present and the future.Based on the evolution characteristics of China's animal husbandry regional layout in the past 40 years and the requirements of China's current era for the development of animal husbandry,combined with the latest research results of animal husbandry layout at home and abroad,this paper using the theory of location and comparative advantage to study the rational distribution and development of animal husbandry areas in China.The first and second parts are the introduction and conceptual theory of this paper,mainly elaborating the research background and significance,research objectives,research contents,research methods and research routes of this paper,and summarizing the relevant research literature at home and abroad at present,and defining and explaining the related concepts and theories involved.The third part divides the development stage and regions of animal husbandry in China,and defines six animal husbandry regions: qing-xin-meng plateau,loess plateau,southwest mountain region,northeast region,huang-huai-hai region and southeast region.Based on the study of the evolution characteristics of the regional distribution of animal husbandry in China and the concentration degree of animal husbandry,it is shown that the regional distribution of animal husbandry in China presents a general trend of agglomeration and transfer to the north,the formation of qing-xin-meng plateau,loess plateau area of sheep breeding;Pig and beef cattle breeding in mountainous areas of southwest China;Milk production in northeast China;Evolution of regional distribution of poultry farming in huang-huai-hai region.However,the dominant position of traditional pastoral areas such as qing-xin-meng plateau area and loess plateau area is gradually declining.The proportion of animal husbandry in southeast region and huang-huai-hai region is gradually decreasing,and the dominant position of animal husbandry in northeast region is increasingly significant.The fourth part,the comparative advantages of the six animal husbandry regions are analyzed.The advantageous areas of pig breeding are the southwest mountainous area and the southeast area.The dominant areas of milk production are qing-xin-meng plateau and northeast China.Domestic fowl is cultured preponderant area is northeast area and area of huang-huai-hai region.The results show that the commodity rate of beef cattle,mutton sheep and milk is very high in qing-xin-meng plateau and loess plateau.The pig commodity rate in southwest mountainous area is much higher than the national level.The commodity rate of beef cattle,live pigs,milk and poultry in northeast China is very high.The poultry commodity rate in huang-huai-hai region is only slightly higher than the national level.The commodity rate all kinds of livestock in southeast China is far lower than the national average.The fifth part is the analysis of the changing factors of the regional layout of animal husbandry in China by using the multiple linear regression model.The results show that the traditional natural factors have a decreasing influence on the regional distribution of animal husbandry in China,while the economic factors have a deepening influence.The distribution of animal husbandry will gradually migrate to areas with lower economic development level and converge to areas with lower non-agricultural employment opportunities.On the whole,the regions with higher grain yield are more suitable to develop animal husbandry.Transportation conditions and information flow will greatly promote the development of modern animal husbandry.The sixth part is the conclusion and suggestions of this paper.After sorting out and analyzing the research results of this paper,some suggestions are put forward to promote the layout of animal husbandry in China,hoping to provide some references for the decision-making of animal husbandry development in China.
