【摘要】：“紧凑城市”被认为是可以提高城市运行效率、节约资源和能源消耗，实现建设资源节约型和环境友好型社会的一种可持续的城市发展策略。伴随着城市群、大都市带、都市圈等庞大的、多核心、多层次的城市集团或区域空间组织形式的产生，从区域角度出发的区域空间集中和分散研究逐渐纳入其中。因此，实现“紧凑型”的发展目标不仅是就城市论城市，还应从区域角度考虑。本文在总结国内外相关研究基础上，分析解读了紧凑城市的概念内涵，从空间紧凑、结构良好、效率较高三个方面构建了测度城市内部紧凑度的指标体系，测算了西北地区六大城市群城市内部紧凑度，并运用多元逐步线性回归方法研究其影响因素。结论如下：①西北地区六大城市群内城市紧凑度总体水平不高，有待进一步提高，以实现城市的可持续发展，且极化现象明显；②六大城市群内城市紧凑度平均水平，关中-天水城市群（0.159）＞呼包鄂城市群（0.108）＞天山北坡城市群（0.059）＞兰白西城市群（-0.039）＞酒嘉玉城市群（-0.164）＞银川平原城市群（-0.306）；③经济密度、人口密度、经济增长弹性、路网密度、建成区绿化覆盖率、城市建设用地信息熵以及城市形态紧凑度等，对城市紧凑度的影响程度相对较大，且影响程度依次减小。研究了城市内部紧凑度及其影响因素之后，从区域角度出发对城市之间紧凑度进行测度研究。从产业紧凑、空间紧凑和交通紧凑三个方面入手，构建城市群综合紧凑度测度模型。测度结果表明：①西北地区城市群综合紧凑度整体水平较低，关中-天水城市群综合紧凑度㧐兰白西城市群㧐呼包鄂城市群㧐天山北坡城市群㧐银川平原城市群㧐酒嘉玉城市群；②相对而言，关中-天水城市群综合紧凑度略高，兰白西城市群、呼包鄂城市群、天山北坡城市群、银川平原城市群综合紧凑度差别不大，然其产业紧凑度、空间紧凑度、交通紧凑度内部差异较大。产业紧凑度，呼包鄂城市群和天山北坡城市群具有相对优势，酒嘉玉城市群产业紧凑度具有显著劣势；空间紧凑度，关中-天水城市群具有显著优势，，呼包鄂城市群、天山北坡城市群、银川平原城市群、酒嘉玉城市群水平相当，且较低；交通紧凑度，兰白西城市群群和银川平原城市群相对较高，其它城市群水平相当。③不同城市群产业紧凑度、空间紧凑度、交通紧凑度发展状况不同，因此须结合各城市群自身发展现状对其紧凑度发展进行调控。整体上，合理调整城市群产业结构与布局、调配城市群交通网络、提高网络节点的通达度、促使区域空间网络化、完善城市群政策体系，将城市群建成互惠、互利、互律的利益共同体，解决目前各城市自成一体、分散建设、重复建设等问题，建设精明增长的高效节约型城市群。
[Abstract]:"compact city" is considered as a sustainable urban development strategy which can improve the efficiency of urban operation, save resources and energy consumption, and realize the construction of resource-saving and environment-friendly society. With the emergence of urban agglomeration, metropolitan belt, metropolitan area and other huge, multi-core, multi-level urban groups or regional spatial organization form, the regional spatial concentration and dispersion from the regional perspective gradually come into being. Therefore, to realize the development goal of "compact type" is not only to discuss the city, but also to consider from the regional point of view. On the basis of summarizing the relevant research at home and abroad, this paper analyzes and interprets the concept connotation of compact city, and constructs an index system to measure the compactness of the city from three aspects: compact space, good structure and high efficiency. The internal compactness of six urban agglomerations in Northwest China is calculated and the influencing factors are studied by using multiple stepwise linear regression method. The conclusions are as follows: (1) the overall level of urban compactness in the six urban agglomerations in Northwest China is not high, which needs to be further improved in order to realize the sustainable development of the city, and the phenomenon of polarization is obvious; (2) the average level of urban compactness in the six urban agglomerations, Guanzhong Tianshui Urban agglomeration (0.159) > Hubao E Urban Group (0.108) > Tianshan North Slope Urban Group (0.059) > Lanbexi Urban agglomeration (- 0.039) > Jiujiayu Urban agglomeration (- 0.164) > Yinchuan Plain City City group (- 0.306); (3) Economic density, population density, elasticity of economic growth, road network density, green coverage rate of built-up areas, information entropy of urban construction land and compact degree of urban form have relatively great influence on urban compactness. And the degree of influence decreased in turn. After studying the internal compactness and its influencing factors, the paper studies the measurement of intercity compactness from a regional point of view. A comprehensive compactness measurement model of urban agglomeration is constructed from three aspects: compact industry, compact space and compact traffic. The results show that: 1 the overall level of comprehensive compactness of urban agglomeration in northwest China is low, and the comprehensive compactness of Guanzhong Tianshui urban agglomeration? Lan Bai Xi City Group? Hubao E City Group? Tianshan North Slope Urban agglomeration? Yinchuan Plain Urban agglomeration? Jiujiayu Urban agglomeration; (2) comparatively speaking, the comprehensive compactness of Guanzhong Tianshui urban agglomeration is slightly higher, the comprehensive compactness of Lanbexi urban agglomeration, hubao and Hubei urban agglomeration, Tianshan northern slope urban agglomeration and Yinchuan plain urban agglomeration is not different, but its industrial compactness and spatial compactness are not obvious. There is a great difference in the degree of traffic compactness. Industrial compactness, Hubao and Hubei urban agglomeration and Tianshan northern slope urban agglomeration have relative advantages, Jiujiayu urban agglomeration has significant disadvantages; Spatial compactness, Guanzhong-Tianshui urban agglomeration has significant advantages, Hubao-Hubei urban agglomeration, Tianshan north slope urban agglomeration, Yinchuan plain urban agglomeration, Jijiayu urban agglomeration level is comparable, and lower; The urban agglomeration of Lanbexi and Yinchuan Plain is relatively high, and the other urban agglomerations are of the same level. 3 different urban agglomerations have different development conditions such as industrial compactness, spatial compactness and traffic compactness. Therefore, the compact development of urban agglomerations should be regulated in combination with their own development situation. On the whole, we should adjust the industrial structure and layout of the urban agglomeration reasonably, allocate the traffic network of the urban agglomeration, improve the accessibility of the network nodes, promote the regional spatial networking, perfect the policy system of the urban agglomeration, and build the urban agglomeration into mutual benefit and mutual benefit. The mutual law of interest community, to solve the current problems of each city, decentralized construction, repeated construction and other issues, to build a smart growth of efficient and economical urban agglomeration.
