Study On The Mechanism And Regulation On The Process Of Novelty Of Socio-ecological System In Mining Areas

The large-scale exploitation of mineral resources has contributed to the industrialisation of China and has made a huge contribution to social and economic development.However,after the depletion of resources,many mining areas have faced serious difficulties due to the stagnation of economic and social development as a result of mine closure,while the ecological environment has been damaged.Under these circumstances,finding a transformative development model that suits the current situation is the fundamental path to ensuring the sustainable development of mining areas.The evolution of the socio-ecological system of the mine after closure is dramatic and complex,and the high degree of coupling of ecological,economic and social subsystems determines that the evolution is not a simple linear process.The operational mechanism of the concept of "novelty" fits the logic of change and the practical needs of this particular study area,and is a key grip for research into the characteristics,laws and directions of evolution.However,there has been little discussion of the mechanisms of novelty in studies on the transformation of mining areas at home and abroad,and the quantitative assessment and regulation of novelty has not yet been addressed.The overall objective of this thesis is to systematically examine the evolution of social-ecological systems in mining areas,to reveal the inner mechanisms of the novelty of social-ecological systems in mining areas,and to provide theoretical guidance for high-quality development and avoidance of decline in mining areas.Following a logical combination of theoretical analysis,empirical analysis and model building,the concept and theoretical framework of "novelty" of social-ecological systems in mining areas is firstly proposed,and the process of continuous evolution of system components,structures,functions and landscapes is called "novelty".The concept and theoretical framework of "novelty" of mine socio-ecological systems is firstly proposed.In addition,a DPSIR-based model of the process and mechanism of novelty in mining social-ecological systems is developed to identify and evaluate the degree and state of novelty,discover the driving forces and pressures of novelty,and provide a new basis and pathway for the high-quality development of mining social-ecological systems.Finally,it proposes a new regulation strategy for the social-ecological system in mining areas,analysing in turn the novelty regulation objectives,regulation paths and regulation strategies,and providing new guidelines for the transformation and development of closed mining areas.Introducing the novelty theory into the field of mining social-ecological systems research,the study includes specifying the characteristics and connotations of novelty,developing a model of the novelty process in mining areas,revealing the novelty mechanism,quantifying the effects of novelty,and proposing novelty regulation strategies.The main findings of the thesis are as follows.(1)Under varying degrees of internal dynamics and external pressures,the common paths of evolution in the state of mining socio-ecological systems are not the same,with some achieving novelty,others being abandoned,and others continuing to be developed.Not all mining areas can or have the need to maintain the path of novelty.(2)By novelty we mean the continuous evolution of the mining socio-ecological system as a whole,under driving forces and pressures,towards a positive system component,structure,function and landscape that has not historically existed in the region.(3)The novelty has a unique mechanism that distinguishes it from other socioecological system evolutionary processes.The main drivers of socio-ecological systems in mining areas can be divided into social,economic and ecological ones.The driving forces and pressure indicators have a continuous influence on the state indicators that accompany the whole process of novelty,and the changes in state have an significant impact on the functioning of the regional system.In turn,the subject of novelty makes specific novelty regulation strategies to respond to the goals of the process of novelty.(4)The effect of the process of novelty is significant,raising the level of landscape multifunctionality,including the comprehensive enhancement of various social,ecological and economic functions,and the tendency for the relationship between the various functions to move from trade-offs to synergies.(5)The regulation of novelty is an important way to achieve the goal of sustainable development of the social-ecological system in mining areas.In order to achieve the goal of overall improvement of the regional social,ecological and economic environment,different regulation paths such as deceleration,stabilisation or acceleration are chosen for different process of novelty stages.The specific regulation strategy corresponds to the regulation target,and is divided into ecological-economic regulation,economic-social regulation,ecological-social regulation and sustainable landscape regulation strategies,providing new guidelines for the development of closed mine areas.In the case of mining areas,for example,many socio-ecological systems on Earth have been severely damaged and have undergone profound succession.It is extremely important to study the theoretical connotations,evolutionary mechanisms,emergence conditions,end thresholds and assessment paradigms of the process of novelty of such systems,and to scientifically formulate action plans and preferential criteria for regional development according to the degree of process of novelty.The paper has 51 figures,36 tables and 228 references.
