摘　　要：为促进区域交通、产业和生态的协调发展,推动区域城市的高质量发展,选取甘肃省及省内12个城市为研究对象,通过耦合度模型和耦合协调度模型探究甘肃省及其城市2010—2019年的交通、产业和生态系统耦合协调关系及时空演化特征,为区域高质量发展提供建议。结果表明:个别年份甘肃省耦合协调度出现下降,整体保持稳定增长趋势,交通、产业和生态系统的耦合协调等级较高;截至2019年,除兰州外,其余城市系统发展水平相比2010年提升较小,耦合协调程度呈良性发展,各城市耦合协调等级均达到勉强协调及以上水平;σ收敛性检验表明各城市耦合协调度的变异系数较大,耦合协调发展差距较大,未来要加强各城市的发展合作,并根据实际情况制定差异化发展政策。In order to promote the coordinated development of regional transportation,industry and ecology,and promote the high-quality development of regional cities,in this paper Gansu Province and its 12 cities were selected as the research subjects and the coupling and coordination relationship between transportation,industry and ecosystem in Gansu Province and its cities from 2010 to 2019 and its temporal and spatial evolution characteristics through coupling degree model was explored,so as to provide suggestions for regional high-quality development.The results showed that the coupling coordination degree of Gansu Province decreased in individual years,and maintained a steady growth trend as a whole,and the coupling coordination degree of transportation,industry and ecosystem was high.By 2019,except Lanzhou,the system development level of other cities has improved slightly compared with that of 2010,and the degree of coupling and coordination has become a benign development.The coupling and coordination level of each city has reached the level of barely coordination and above.The convergence test shows that the variation coefficient of coupling coordination degree among cities is large,and the coupling coordination development gap is large.In the future,it is necessary to strengthen the development cooperation among cities and formulate differentiated development policies according to the actual situation.
