Research On Adaptive Management Of Forest Ecosystem In North Shanxi

Forest is an important terrestrial ecosystem,and the management of forest ecosystem is an important way for its sustainable development.With the development of system theory,people gradually realize that there is no pure ecosystem that does not interact with human activities.The forest ecosystem is interwoven with the human social and economic system,and the management of forest ecosystem is facing great challenges.In recent years,as a new concept and method,adaptive management provides a new management idea for the field of resource management,and has received extensive attention.Based on the viewpoint of complex adaptive system,this paper uses the geospatial analysis method and investigation and analysis methods to evaluate the condition of the forest ecosystem in north Shanxi and analyze the development space potential which taking 20 counties in north Shanxi as the research area.Then,based on the theories of social ecosystem and adaptive management,the characteristics and major elements of forest ecosystem as a complex adaptive system has been explained,and its adaptive management process has been analyzed.Finally,according to the above study,this paper establishes adaptive management objectives,and proposes recovery strategies.This study shows that:(1)Based on historical and practical analysis results,it is shown that in the history of north Shanxi,the forest ecosystem was in good condition,the vegetation was dense,and the vegetation coverage rate was sharply reduced as a result of uncontrolled destruction of forest resources by humans in various periods.Since 1949,efforts made from the ecological and social aspects have had a great impact on forest resources in northern Shanxi,and the vegetation coverage has been greatly improved.However,the development of forest ecosystem in this area is still insufficient and faces many problems.It can be seen that the north Shanxi is a forest zone and its actual level of vegetation and the past still have a large gap.(2)In the study of the development of the space potential of the forest ecosystem,the north Shanxi is divided into 6 sub-regions which include the loess hilly in northwest Shanxi,the mount Guanqin,the loess hilly in north Shanxi,the basin in north Shanxi,mount Hengshan,and mount Wutai.From the perspective of ecological land use,the paper carefully analyzes the potential spatial and spatial sources of each sub-region,and concludes that the development potential of forest ecosystems in north Shanxi.The results show that there is great potential for ecological space in the north of Shanxi Province.The potential space for the development of forest ecosystems is about 580,000 hm~2,and the main space comes from grassland.(3)Based on the view of the complex adaptive system,this paper points out its adaptive management process and development stage,and puts forward the goal and strategy of adaptive management by constructing the analysis framework of the forest ecosystem in north Shanxi.The result shows that forest ecosystem has complex components.These components adapt to each other through interaction.Therefore,forest ecosystem management is a complete cycle system.This paper holds that the North Shanxi will be in the recovery stage of the forest ecosystem for a long time in the future.Therefore,it is necessary to establish the core goal of the coordinated development of the forest ecological system with social ecosystem.And this paper puts forward three main management strategies for quality improvement and expansion of plantation forests,protection and development of natural forests,and improvement of governance systems,with a view to providing reference for restoration of forest ecosystems in north Shanxi.
