甘肃省张掖市地处我国西北干旱区，该地区属于内陆河流域绿洲城市，生态环境极其脆弱，研究其新型城镇化与生态安全耦合协调发展问题显得尤为重要。通过借鉴国内外城镇化与生态环境耦合协调发展现有的研究成果，以2005—2017年张掖市统计数据为依据，建立综合评价指标体系，运用熵权法求各项指标权重，设立了耦合协调度模型，测算新型城镇化与生态安全耦合协调发展的综合指数，来表征该区域的耦合关系。结果表明：13 a间系统由低水平耦合协调——拮抗时期——磨合阶段——高水平耦合发展。新型城镇化发展水平基本保持稳步上升的态势；而生态环境综合水平尽管总趋势是向好发展，以2011年为拐点明显波动。新型城镇化与生态安全的耦合协调度持续向好，2012年达到峰值后一直保持在大于0.9的耦合协调度极高水平。最后提出促进该城市新型城镇化与生态安全耦合协调发展的政策建议。

Considering the oasis city Zhangye,Gansu Province,in the arid region of Northwest China,as the object of study,and constructing new types of urbanization and index systems of ecological environment,this research analyzes coordinated development between new types of urbanization and ecological environment.We used the case of Zhangye between 2005 and 2017 and employed the entropy research method to calculate weight values.According to the feedback at different stages,we were able to give detailed descriptions of changing processes in the system,for example,coupling coordination at low levels,antagonism periods,and running-in periods to high level coupling.Our results indicate that new types of urbanization developed steadily in Zhangye between 2005 and 2017.Although comprehensive development of the ecological environment presents a better trend on the whole,it shows fluctuations in time alignment,decreasing to its lowest point (0.397) in 2011,before maintaining a steady rising trend from 2011 until 2017.These results also show that the degree of coupling between new types of urbanization and ecological security in Zhangye rose from 0.457 in 2005 to 1.000 in 2012.Thereafter,the degree of coupling coordination remained at a very high level above 0.9.The conclusions made by this study are as follows: according to the coupling calculated for the studied period,the degree of environmental pollution in Zhangye is shown to be comparatively smaller when urbanization develops at a slower speed.When urbanization develops more rapidly,the pollution of the ecological environment increases and negative feedbacks become more obvious.However,with the implementation of sustainable development and circular economy strategies,it is planned to improve urban and rural ecological environment protection and make more effort to manage the ecological environment in order to release positive feedbacks.Towards this goal,the coupling between new types of urbanization and the ecological environment in Zhangye is able to develop step by step.New types of urbanization and ecological environment change and develop alternatively,such that the coupling coordination presents a general trend of gradual strengthening.At present,the trend for coupling the development of new types of urbanization and ecological security in Zhangye is such that new urbanization develops more prominently than the ecological environment.Therefore,in order to promote a better interaction,it is essential to strengthen the protection and management of ecological environment when advancing new urbanization.It is therefore necessary to constantly regulate the coordinated development of new types of urbanization alongside the ecological environment.
