Economic-social-ecological coupling coordination from the perspective of sustainable societal safety:take Qinghai Province as an example
Societal safety is the result of coordinated development of several subsystems,and the cou-pling and coordination of economic development,social stability and ecological sustainability is the premise of realizing sustainable societal safety.This paper puts forward the concept of sustainable societal safety,and expounds its connotation,spatial elements and interaction mechanism.Then,by constructing the index sys-tem,the coupling coordination level of county economic development,social stability and ecological sustainability in Qinghai Province from 2000 to 2019 was evaluated.Finally,it tries to reveal the temporal and spatial evolution law of sustainable societal safety in Qinghai Province.The results show that:(1)Economy is developing rapidly,and the regional differentiation is remarkable.Xining and Haixi have a higher level,Haidong and Hainan are above the average,Haibei and Huangnan are below the average,and Guoluo and Yushu are lagging be-hind.Social and economic stability is strong,and it is greatly affected by natural disasters.Xining,Haixi and Haidong have higher scores,Haibei and Hainan are in the middle,and Yushu,Guoluo and Huangnan have lower scores.Ecological environment is slowly improving,and the spatial pattern is relatively stable.Low-value areas are distributed in Xining,Haidong and Haixi,Huangnan,Guoluo and Yushu maintain a high level,Hainan and Haibei rank in the middle reaches.(2)The degree of coordinated development of the three systems is fluctuating and rising.The coupling and coordination level along the Qinghai-Tibet Railway is high,and Huangnan,Guoluo and Yushu areas need to be improved.(3)The description of the spatial and temporal characteristics of the coupling level not only reveals the systematicness of sustainable societal,but also proves the feasibility of measuring the societal safety level based on the coupling level of the social structure system.
