COUPLING COORDINATION BETWEEN RESOURCES ENVIRONMENT AND ECONOMIC DEVELOPMENT IN TIANSHUI CITY
To study their coupling coordination between resources environment and economy in Tianshui City,this paper establishes an index system to evaluate Tianshui's resources environmental carrying capacity and economic development level,and uses entropy and comprehensive indictors to measure Tianshui's 2010 to 2021 resources environmental carrying capacity and economic development level,and applies coupling coordination model to study their coupling coordination,and employs obstacle model to identify the major obstacles impeding Tianshui's resources environmental carrying capacity and economic development level.Tianshui's comprehensive evaluation index of 2010 to 2021 resources environmental carrying capacity shows a rising trend,up to 0.839 5 in 2021 from 0.120 1 in 2010,and its comprehensive evaluation index of economic development level also has increased to 0.866 9 in 2021 from 0.184 5 in 2010.The both's coupling coordination degree value has waveringly climbed to 0.635 1 in 2021 from 0.272 8 in 2010,with coupling coordination class raised to preliminary coupling from intermediate disordered,suggesting an improving coupling coordination degree during 2010 to 2021.The major obstacles against Tianshui's resources environmental carrying capacity include seven factors,water resource per capita(X2),population density(X3),industrial waste gas discharge(X6),industrial solid waste discharge(X8),proportion of the 2nd industry(X12),proportion of the 3 rd industry(X13),Engel's Coefficient(X16).And six obstacles against Tianshui's economic development level include total retail sales of consumer goods(Y4),proportion of the 1st industry(Y5),proportion of the 3rd industry(Y7),per capita disposable income of urban residents(Y8),per capita disposable income of rural residents(Y9),and Engel's Coefficient(Y10).All obstacles above suggest that Tianshui's coordination between resources environment and economic development be jointly constrained by natural resources,environmental protection,economic strength,economic structure and people's living levels.
