我国自改革开放以来，经过四十多年时间的发展，各地区城市蓬勃发展、综 合实力全面提升，进入 21 世纪后，全国范围内的城市规模及城市数量急剧增加， 在城镇化发展越来越快速的同时，也对城市的管理提出了更高的要求。十九大报 告在总结以往实践经验的基础上提出的“十四条坚持”，是构成新时代坚持和发 展中国特色社会主义的基本方略，其中明确地提出“坚持人与自然和谐共生”、 “实行最严格的生态环境保护制度”。社会生活中处处包含着社会单位与其生存 环境之间的关系，这种关系同生态学所研究的生态系统模型非常相似，因此对社 会个体和群体的发展变动以及社会学的相关内容，都可以运用生态学的相关理论 和方法进行研究，这已经在很多学者的研究中体现了出来。而生态位就是每个个 体或群体在其所处环境中所占的地位和影响力的大小，人们将生态位的概念不断 发展拓新，最终引入到城市各方面的发展中。 论文以甘肃省 14 市（州）各方面发展情况为研究对象，收集利用 2017 年甘 肃省城市经济、人口、生态环境、社会服务和基础设施方面的数据，在深入分析 国内外城市发展研究现状基础上，立足于城市生态经济系统，以城市生态文明理 论、生态经济学理论为指导，基于生态位理论，结合分形法、熵权法、泰尔指数 测算方法和统计分析法，研究甘肃省城市生态经济系统发展的差异性。首先，在 生态经济学视域下对甘肃省城市生态经济发展概况进行了介绍；其次，结合生态 文明理论和城市生态位理论，构建一个甘肃省的城市生态位评价指标体系，对甘 肃省城市生态经济系统的差异性进行评价分析；然后以生态位理论为基础，用城 市分形理论和泰尔指数测算方法，进一步分析甘肃省城市生态经济系统的差异 性，对各个层次的城市生态位构建提出建议，以期为相关部门的决策提供定量化 的依据。

After more than 40 years of development since China's reform and opening up, cities in various regions have developed vigorously and their comprehensive strength has been enhanced comprehensively. In the 21st century, the cities’ scale and number in China are increasing rapidly, and the process of urbanization is accelerating, which require higher requirements for the renewal and management of urban functions. On the basis of summarizing past practices, the report of the 19th CPC national congress puts forward the "14 Points of adherence" that constitute the basic strategy for upholding and developing socialism with Chinese characteristics in the new era. Social life everywhere contains the relationship between social units and their living environment, which is very similar to the research contents of ecology. Therefore, relevant theories and methods of ecology can be used to study relevant contents of sociology, and this phenomenon has been reflected in the research of some scholars. Niche theory is the threshold value of each organism in the environment, and the concept of niche is constantly expanded and eventually introduced into the development of cities. Taking the development of 14 cities in Gansu province as the research object, this thesis collects and uses the data of urban economy, population, ecology, environment and infrastructure in Gansu province in 2017. Basing on the following evidences, which contain the deep analysis on the basis of urban development and research status at home and abroad, the urban Eco-economic system, the theory of Ecological economics, the instruction of urban Ecological civilization theory, the Ecological niche theory, the Fractal method, the Entropy weight method, Thayer index measurement and Statistical analysis method, this thesis will study the differences of the urban Ecological system and Economic development of Gansu province. Firstly, the development of Urban ecological economy in Gansu province is introduced from the perspective of Ecological economics. Secondly, based on the theory of Urban niche and Ecological civilization, the Evaluation index system of urban Niche in Gansu province is constructed, and the difference of urban Eco-economic system in Gansu province is evaluated and analyzed. Thirdly, based on the Niche theory, the difference of urban Eco-economic system in Gansu province is further analyzed by using the urban Fractal theory and the Thayer index method, and suggestions will be put forward for the construction of urban Eco-economic system at various levels, so as to provide quantitative basis for the decision of related departments.
