Research On Evaluation Of Collaborative Development Level Of Life Community In Mining Area Under Multi Factor Coupling

Mineral resources provide an important material basis for human survival and development.China is a large country of mineral resources.The development of mineral resources has led to the development of social economy in China.At the same time,due to the lack of environmental awareness,predatory and extensive development mode has caused damage to the ecological system of mining area,and seriously restricted the development of social economy in mining area.How to protect the ecological environment of mining area in the process of mining mineral resources,ensure the development of mineral resources in the ecological protection,so as to promote the sustainable development of mining industry.Firstly,this paper defines the symbiotic system of the coordinated development of human production and life and the mining area ecosystem-the mining area life community system,and analyzes the elements of the mining area life community system and the relationship between them.On this basis,this paper takes Sandaozhuang mining area of Luanchuan,Luoyang City,Henan Province as the research object,and constructs the evaluation index system of life community system in mining area.The comprehensive development level of human,plant,animal and microbe symbiotic subsystems in mining area was evaluated by using the function of function.Based on the coupling coordination model,the cooperation of human plant symbiosis system,human animal symbiosis system,human microbial symbiosis system and mining arealife community system in 2008-2017 is analyzed The development level was evaluated and the results showed that:(1)In the 10 years of the research period,the comprehensive index of human symbiotic subsystem in Sandaozhuang mining area increased from 0.3588 to 0.6786,with an average growth rate of 8.91%,at a high level.The comprehensive index of plant symbiotic subsystem in Sandaozhuang mining area increased from 0.3659 to 0.5692,with a steady growth overall,with an average annual growth rate of 5.56%,slower than that of human symbiotic subsystem.From 2008 to 2017,the comprehensive index of zoological symbiotic subsystem in Sandaozhuang mining area decreased from 0.4657 to0.3514,with an average annual decrease of 1.84%.The comprehensive index of microbial symbiotic subsystem in Sandaozhuang mining area shows a decreasing trend,from 0.5736 in 2008 to 0.4378 in 2017,with an average annual decrease of 2.36%.On the whole,the average comprehensive indexes of human,plant,animal and microorganism in the life community system of Sandaozhuang mining area from 2008 to 2017 are 0.5107,0.4867,0.4418 and 0.4966,respectively,of which the average comprehensive index of human is the largest,indicating that the human symbiotic system has the greatest impact on the life community of mining area The system has the greatest impact,which is inseparable from the protection of the ecological environment of the mining area by the local government and enterprises.(2)The coupling and coordination degree of human plant symbiosis system,human animal symbiosis system and human microorganism symbiosis system all show different degrees of rising state,among which the coupling and coordination degree of human plant symbiosis system increases greatly,while the coupling and coordination degree of human microorganism symbiosis system increases slightly.In 2008,the coupling and coordination degree of the life community system in Sandaozhuang mining area was 0.3517,which was at a different level of development.The main reason was that the exploitation of mineral resources caused pressure on the natural ecosystem of the mining area,such as land destruction,air pollution and the destruction of groundwater resources,which destroyed the living habitat of animals,plants and microorganisms.In 2010,the coupling coordination degree of the life community system in Sandaozhuang mining area was 0.4243,entering the stage of slightdiscrepancy.By 2017,the coupling coordination degree of the life community system in the mining area reached 0.5212,which was a barely collaborative level.From the perspective of the coupling coordination degree of the life community system in Sandaozhuang mining area in the past 10 years,the whole system shows a steady rise in the first out state.
