Research On The Ecological Construction Of Youyu From The Perspective Of System Philosophy

The relationship between man and nature has always been a concern of human society.The governance of ecological problems is not only to meet the needs of human survival,but also to realize the harmonious development of man and nature,and to build an important foundation for social ecological civilization.Soil and water loss,land desertification,reduced forest and grassland resources,and reduced biodiversity are the main issues of the current ecological environment.The ecosystem is composed of many factors and has a large and complex structure.Therefore,it is a huge systematic project to manage the ecological environment.The ecological environment of Youyu County,Shanxi Province has been severely damaged.After more than 70 years of ecological management and construction,Youyu has changed from a "barren land" to a "plugged oasis".From the perspective of system philosophy,it explores the ecological restoration of right jade,and finds the correct path of ecological construction,which provides a new way of thinking and perspective for regional ecological environment governance and ecological construction.The ecosystem of Youyu County is a complex giant system,and the ecological construction of Youyu County is a systematic project.The development of ecosystem in Youyu County has gone through four stages.From "The gradual degradation of the ecological environment before the founding of new China";"In the 1950 s,large-scale afforestation and the gradual restoration of the system were carried out in accordance with local conditions";"The Development Period of Optimizing Ecological Governance in the1980s";And to the "Optimization Period of Building a Composite Ecological Network System in the 21 st Century".The generation and evolution stages of the ordered ecosystem of Youyu are explored,so as to reveal the orderly evolution mechanism of the system.Under the premise that the system is far from equilibrium and sufficiently open,through large-scale afforestation,desertification and river basin measures to increase the input of negative entropy in the system,promote the continuous interaction of various elements in the agricultural,forestry and animal husbandry systems.It is of practical significance to explore the ecological construction process of Youyu with systematic thinking in order to adhere to the systematic working method to manage the ecology and create a world ecological community,and to solve the ecological environment problems in ecologically fragile areas,and then to build the harmonious development between man and nature and promote the modern ecological construction.
