改革开放以来，我国经济取得巨大发展，综合国力持续稳定上升，进一步推 动了城市化的发展，使得整个城市人口不断增长，城市空间快速扩展，人们的生 活水平得以改善。但是城市化进程也会给城市带来诸多弊端，如交通拥挤、住房 紧张、资源匮乏和环境污染等问题，这些都是城市可持续发展过程中阻碍物。城 市化过程不可避免地影响和改变着城市的生态环境水平，所以有必要对城市化和 生态环境间协调关系进行分析，处理好二者之间的协调关系，避免区域内各类问 题频出，促进区域城市化可持续发展。 甘肃省位于西北内陆，经济发展处于欠发达状态，同时又是生态环境相对脆 弱地区，既需要快速发展经济又必须要保护脆弱的环境。如何协调城市化与生态 环境的关系，已经成为西部地区在城市化过程中不能回避且亟需解决的问题。基 于以上考虑，论文在深入分析甘肃省的城市化和生态环境研究现状的基础上，结 合城市生态系统理论和共生演化理论，构建涵盖城市系统与生态环境系统的城市 生态系统评价指标体系，运用熵值法对各项指标赋予相应的权重，加权求和得到 两个系统的发展水平。借助 Lotka-Volterra 模型对城市化发展和生态环境二者之 间的动态竞争关系进行研究，根据协调关系测算公式得出二者间协调关系；之后 根据协调水平测算公式得出二者间协调水平，利用层次聚类分析方法将协调水平 分为三类；最后根据城市生态系统协调发展评判准则，得出协调度综合评价，剖 析出当前甘肃省城市化发展格局，以期为未来甘肃省城市化协调性发展提供可操 作性的对策和建议。

Since the reform and opening up, China's economy has achieved tremendous development, and its comprehensive national strength has continued to rise steadily, further promoting the development of urbanization, making the population of the entire city continue to grow, the urban space is expanding rapidly, and people's living standards are improved. However, the urbanization process will also bring many disadvantages to the city, such as traffic congestion, housing shortages, resource scarcity and environmental pollution, which are obstacles in the process of sustainable urban development. The urbanization process inevitably affects and changes the level of the city's ecological environment. Therefore, it is necessary to analyze the coordination relationship between urbanization and the ecological environment, and to handle the coordination relationship between the two to avoid frequent problems in the region. Promote the sustainable development of regional urbanization. Gansu Province is located in the northwest of China, and its economic development is underdeveloped. At the same time, it is a relatively fragile ecological environment. It needs to develop the economy rapidly and protect the fragile environment. How to coordinate the relationship between urbanization and ecological environment has become an issue that cannot be avoided and urgently needed to be solved 兰州财经大学硕士学位论文 甘肃省城市化与生态环境协调性分析 V in the process of urbanization in the western region. Based on the above considerations, based on the in-depth analysis of the status quo of urbanization development and ecological environment research in Gansu Province, combined with urban ecosystem theory and symbiotic evolution theory, the paper constructs an urban ecosystem evaluation index system covering urban systems and ecological environment systems. The entropy method assigns corresponding weights to various indicators, and the weighted summation obtains the development level of the two systems. With the Lotka-Volterra model, the dynamic competition relationship between urbanization development and ecological environment is studied. According to the coordination relationship calculation formula, the coordination relationship between the two is obtained. Then, according to the coordination level calculation formula, the coordination level between the two is obtained. The hierarchical level analysis method is used to classify the coordination level into three categories. Finally, according to the evaluation criteria of coordinated development of urban ecosystem, the comprehensive evaluation of coordination degree is obtained, and the current urbanization development pattern of Gansu Province is analyzed, in order to coordinate the urbanization of Gansu Province in the future. Develop countermeasures and recommendations that provide operability.
