甘南黄河重要水源补给区生态经济耦合协调发展研究

［目的］探究甘南黄河重要水源补给区生态与经济耦合协调发展趋势，为区域生态与经济协调发展提供决策依据。［方法］基于区域协调发展理论，构建生态环境与社会经济的评价指标体系，定量分析了2007—2017年生态环境与社会经济的耦合协调过程与变化趋势。［结果］生态环境综合评价值呈现波动中增长的发展趋势，社会经济综合评价值除了2017年也一直呈上升趋势，且上升幅度更大，区域生态经济系统耦合度发展平稳，一直处于拮抗状态。耦合协调类型经历了濒临失调衰退型—勉强耦合协调型—中级耦合协调型—勉强耦合协调型4个发展阶段。［结论］区域的生态环境调节能力逐步提高，社会经济发展水平显著提升。生态环境与社会经济耦合度与耦合协调度基本呈现相同的变化趋势，说明生态环境与社会经济持续向着协调发展的方向不断演进。未来研究区应通过加强生态环境治理，促进区域内社会经济的绿色转型升级，优化现有生态环境保护支撑体系，提升区域生态经济系统的协调发展水平。

COUPLING COORDINATED DEVELOPMENT OF ECOLOGICAL ECONOMIC SYSTEM IN THE IMPORTANT WATER SUPPLY AREAS OF THE YELLOW RIVER IN GANNAN

Harmonious development of eco economy is the prerequisite of regional sustainable development. It is essential to explore the development trend of ecology and economy in the important water supply area of the Yellow River in Gannan, and it could provide a basis for decision making for the coordinated development of regional ecology and economy. Based on the theory of regional coordinated development, the evaluation index system of ecological environment and socio economy was constructed, and the coupling and coordination process and change trend of ecological environment and socio economy from 2007 to 2017 were quantitatively analyzed. The results of the study showed that the ecological and environmental comprehensive assessment value had shown a trend of growth in fluctuation, the socio economic comprehensive assessment value had also been on the rise in addition to 2017, and the increase was even greater. The coupling of regional ecological and economic systems had developed smoothly and had been in an antagonistic state. The coupling coordination type had gone through 4 development stages of endangered disorder recession type barely coupled coordination type intermediate coupling coordination type barely coupled coordination type. In summary, the adjustment ability of regional ecological environment has been gradually improved, and the level of social and economic development has been significantly improved. The coupling degree and coupling coordination degree of ecological environment and social economy basically shows the same change trend, indicating that the ecological environment and social economy continues to evolve in the direction of coordinated development. In the future, the study area should strengthen the ecological environment governance, promote the green transformation and upgrading of the socio economic, and optimize the existing support system of ecological environment protection, to enhance the coordinated development level of the regional ecological economic system.
