【摘要】：城市土地是人类活动最集中的地域,是城市发展的载体。城市发展已经成为21世纪全球发展的主题。晋城市主城区作为晋城市政治、经济、文化的核心区域,城市规模不断扩大,城市用地扩展与耕地保护的矛盾日益突出。因此深入剖析晋城市主城区扩展演变过程,探讨晋城市主城区空间扩展的驱动因素,在此基础上提出晋城市城市用地理性扩展的对策建议,可为晋城市城市化健康可持续发展提供科学的决策参考。本文在了解国内外关于城市扩张特征及其驱动力的研究的基础上对2007年晋城市主城区土地利用现状进行了分析；其次选取扩展范围、面积变化、扩展速度、扩展强度、扩展弹性、扩展结构等城市用地扩展指标对晋城市主城区1985年—2007年城市用地扩展的空间变化和数量变化进行分析；然后在对晋城市城市用地扩展与地区生产总值、人均GDP、全社会固定资产投资额、第二三产业增加值比重、第二三产业劳动力比重、公路里程、城市维护费、非农业人口、城镇居民人均可支配收入、社会商品零售总额等自然社会经济驱动因素进行相关性分析的基础上,运用主成分分析法提取主要驱动因子并以此建立了多元线性回归的驱动力模型；最后根据研究结果,分析了当前晋城市主城区扩展存在的问题,并据此提出促进城市用地理性扩展的对策建议。通过本文研究,得到结论如下： (1)1985年—2007年晋城市主城区规模处于持续扩大状态,城市空间随时间推移向外部圈层蔓延扩展,城市用地重心总体向东南方向迁移,图斑破碎化程度加剧,形态结构趋向复杂化； (2)1985年—2007年晋城市主城区扩展先后经历了高速扩展、稳定扩展、低速扩展、高速扩展、稳定扩展阶段； (3)1985年—2007年晋城市主城区在扩展演变过程中存在城市用地扩展过快,城市用地扩展规模与城市化发展水平不匹配,用地类型结构虽逐渐完善但仍不尽合理等问题。 (4)晋城市主城区扩展受自然地理、经济发展、社会发展、城市规划等因素的综合影响,其中主要驱动因子为：地区生产总值、人均GDP、全社会固定资产投资额、第二三产业增加值比重、公路里程、城市维护费、非农业人口、城镇居民人均可支配收入和社会商品零售总额。多元线性回归的驱动力模型为：Y=0.01X1-0.055X3+0.135X4+0.001X6+5.24X7+0.576X8-0.031X10-10.488 (5)晋城市城市理性扩展的对策建议包括：合理控制固定资产投资和基础设施建设投入,引导城市用地有序扩展；优化城市用地结构,注重城市扩展与旧城改造相结合；优化区域产业结构,增强城市综合竞争力；继续加强房地产调控力度,合理控制居住用地规模等。
[Abstract]:Urban land is the most concentrated area of human activities and the carrier of urban development. Urban development has become the theme of global development in 21th century. The main urban area of Jincheng as the core region of politics economy and culture of Jincheng. With the continuous expansion of urban scale, the contradiction between urban land expansion and cultivated land protection is increasingly prominent. Therefore, this paper deeply analyzes the evolution process of urban expansion in Jincheng city, and discusses the driving factors of spatial expansion in main urban area of Jincheng city. On this basis, the countermeasures and suggestions for rational expansion of urban land use in Jincheng City are put forward, which can provide a scientific decision reference for the healthy and sustainable development of urbanization in Jincheng City. On the basis of understanding the characteristics and driving forces of urban expansion at home and abroad, this paper analyzes the present situation of land use in the main urban area of Jincheng City in 2007. Secondly, select the extension range, area change, expansion speed, expansion strength, expansion elasticity. The spatial and quantitative changes of urban land expansion in Jincheng City from 1985 to 2007 are analyzed. Then in Jincheng urban land expansion and regional gross domestic product, per capita GDP, total social investment in fixed assets, 23th industrial value added proportion, 23th industrial labor ratio, road mileage. On the basis of the correlation analysis of the natural social and economic driving factors such as urban maintenance fee, non-agricultural population, per capita disposable income of urban residents and total retail sales of social goods, etc. The main driving factors were extracted by principal component analysis (PCA) and the driving force model of multivariate linear regression was established. Finally, based on the research results, this paper analyzes the problems existing in the expansion of the main urban area of Jincheng City, and puts forward some countermeasures and suggestions to promote the rational expansion of urban land use. Through the study of this paper, the conclusions are as follows: From 1985 to 2007, the scale of the main urban area of Jincheng City is in the state of continuous expansion, the urban space extends to the outer circle with the passage of time, and the center of gravity of the urban land generally moves to the southeast. The degree of fragmentation increased and the morphological structure tended to be complicated. From 1985 to 2007, the expansion of the main urban area of Jincheng City has experienced a period of high speed expansion, steady expansion, low speed expansion, high speed expansion and steady expansion stage. 3) from 1985 to 2007, the expansion of urban land is too fast in the main urban area of Jincheng city, and the scale of urban land expansion does not match with the level of urbanization development. Although the structure of land use type is gradually perfect, it is still not reasonable and so on. 4) the expansion of Jincheng main urban area is affected by the factors of natural geography, economic development, social development, urban planning and so on. The main driving factors are regional gross domestic product (GDP) and per capita GDP. Investment in fixed assets of the whole society, the proportion of added value of 23th industries, road mileage, urban maintenance fee, non-agricultural population. Per capita disposable income of urban residents and total retail sales of social goods. The driving force model of multivariate linear regression is: 0. 01X1-0.055X3 0.135X4 0.001X6. 5.24X7 0.576X8-0.031X10-10.488 The countermeasures and suggestions for the rational expansion of Jincheng city include: reasonable control of investment in fixed assets and investment in infrastructure construction to guide the orderly expansion of urban land; Optimize the structure of urban land use, pay attention to the combination of urban expansion and urban reconstruction; Optimize the regional industrial structure and enhance the comprehensive competitiveness of the city; Continue to strengthen real estate regulation and control, reasonable control of the scale of residential land, and so on.
