摘要
以黄河流域甘肃段为例,运用耦合协调发展模型、ArcGIS软件、灰色关联度模型对2010—2020年生态环境、经济发展、城镇化三者耦合协调发展的时空格局及其驱动因素进行研究.结果表明,黄河流域甘肃段生态环境-经济发展-城镇化系统评价值总体呈上升趋势,城镇化和生态环境系统评价值呈持续上升特征,经济发展系统评价值出现波动下降趋势;黄河流域甘肃段各市(州)耦合度呈上升态势并达到较高水平,协调度总体不高,初级协调是主要类型,各市(州)协调度在空间上呈现出“西高东低”的分布态势;生态环境、经济发展、城镇化耦合协调发展的驱动因素影响力从强到弱依次为政府能力、经济发展水平、水资源、产业结构、科技投入、对外开放程度.
Taking Gansu section of the Yellow River basin as an example,the coupling coordination development model,ArcGIS tools and grey correlation degree model are used tOstudy the spatiotemporal differentiation and driving factors of the coupling coordination of ecological environment,economic development and urbanization from 2010 tO2020.The results show that during the study period,the evaluation value of ecological environment-economic development-urbanization system in Gansu section of the Yellow River basin shows a rising trend.The evaluation value of urbanization and ecological environment system shows a continuous upward trend.The evaluation value of economic development system is fluctuating and declining.The level of coupling of cities(prefectures)in Gansu section of the Yellow River basin presents a rising trend and reaches a higher level.The overall coordination degree is not high,and primary coordination is the main type.The coordination degree of cities(prefectures)in Gansu section of the Yellow River shows a distribution of“west high east low”in space.The driving factors of the coupling and coordinated development of ecological environment,economic development and urbanization from strong tOweak are government capacity,economic development level,water resources,industrial structure,scientific and technological investment,and the degree of opening tOthe outside world.
