西北地区资源环境承载力-经济发展-新型城镇化发展耦合协调性研究

为探究西北地区资源环境承载力、经济发展、新型城镇化发展3个子系统之间耦合协调发展状况，以2005—2019年西北五省区作为研究对象，从资源环境承载力、经济发展、新型城镇化发展3个维度构建评价指标体系，借助耦合协调度模型和障碍度模型，研究了各子系统之间的耦合协调关系及作用机理、五省区的系统耦合协调度的时空特征，并进一步分析了其影响因素。研究结果表明：西北地区资源环境承载力-经济发展-新型城镇化发展耦合协调性的综合评价指数在研究期内呈上升趋势，总体上向更好的状态转变，经济发展子系统与新型城镇化发展子系统在研究期内综合评价指数上升明显均大于资源环境承载力子系统，系统耦合度处于较高水平；耦合协调度表现出平稳上升的趋势，耦合协调类型完成了从濒临失调向中级耦合转变；未来西北地区应当树立持续发展理念，提升资源环境承载力水平，转变经济发展方式，促进各子系统协调发展。

Coupling coordination of carrying capacity of resources and environment, economic development and new urbanization development in Northwest China

In order to explore the coupling and coordinated development degree among the three subsystems of carrying capacity of resources and environment, economic development and new urbanization in Northwest China, taking the five provinces and regions in Northwest China from 2005 to 2019 as the research object, an evaluation index system is established from the three dimensions of carrying capacity of resources and environment, economic development and new urbanization. The coupling and coordination relationship and action mechanism among the three subsystems and the temporal and spatial characteristics of system coupling and coordination degree in five provinces and regions are studied by using the coupling coordination degree model and the obstacle degree model, and the relevant influencing factors are further analyzed. The research results show that the comprehensive evaluation index of the coupling coordination of carrying capacity of resources and environment, economic development and new urbanization development in Northwest China has an upward trend during the research period, and it is generally changing to a better state. The increase of the comprehensive evaluation index of economic development subsystem and new urbanization development subsystem during the research period is significantly greater than that of carrying capacity subsystem of resources and environment, and their system coupling degree is at a high level. The degree of coupling and coordination shows a steadily upward trend, and the type of coupling and coordination has completed the transformation from near imbalance to intermediate coupling. In the future, the concept of sustainable development should be established, the level of carrying capacity of resources and environmental should be improved, and the mode of economic development should be changed so as to promote the coordinated development of the three subsystems in Northwest China.
