【摘要】：目前我国正处于城市化进程不断推进、经济建设步伐飞速加快的阶段,为了满足城市人口和产业的用地需求,城市空间不断地向外扩张。郑州市地处中原地带,是全国的交通枢纽中心,河南省经济增长的核心增长极,在国家宏观政策的调整下,城市空间不断向边缘地带扩张,大量的产业资本、社会资源和人口资源不断向城市中心集聚,引发了一系列城市问题,如城市中心承载力不足、职住分离、阶层分化、环境污染、交通拥堵等问题。因此,研究郑州市近三十年城市空间扩展,有助于调整郑州市城市建设方向,构架宜居城市。针对郑州市近三十年城市空间扩展与整合研究,以城市空间理论、空间整合理论为基础,提取了郑州市1988-2014年中五个年份的Landsat TM/ETM+遥感影像数据,利用ArcGIS软件呈现了郑州市近三十年的地域空间演变过程,同时搜集了郑州市近三十年的相关数据,运用定量分析方法,就城市空间扩展速度、强度、弹性及空间紧凑度四个方面进行系统分析,运用灰色关联度分析方法,探究郑州市近三十年城市空间扩展的动力机制。通过分析,发现郑州市在近三十年空间扩展中存在一定的城市发展问题:传统工业化导致居住环境质量出现一定程度的下降;城市空间扩展速度较快,城市内部产业布局调整速度与之相脱节,产业布局相对较为混乱;城市空间弹性偏大,导致城市交通系统效率不高;城市紧凑度较低,导致城市空间布局较为分散,制约城市空间的优化进程。针对城市空间扩展存在的问题,可以从以下几个方面改善:通过加大绿地规划建设面积、控制污染源等措施净化环境系统;改善产业布局,形成一极三圈的圈层式产业结构;通过合理规划交通布局、整合城市道路建设、改善公共交通系统等措施,优化交通运行机制;增强功能分区间的区域联系、合理规划地上地下空间布局,以整合城市地域空间;追逐现代文化建设的同时传承历史文化,通过文化渲染侵润地域空间,实现城市的有机发展。
[Abstract]:At present, China is in the stage of accelerating urbanization and accelerating the pace of economic construction. In order to meet the demand of urban population and industry for land use, the urban space is constantly expanding outwards. Zhengzhou is located in the Central Plains. Is the national transportation hub center, Henan Province economic growth core growth pole, under the national macroscopic policy adjustment, the city space unceasingly expands to the edge belt, the massive industrial capital, Social resources and population resources continue to gather into urban centers, which lead to a series of urban problems, such as insufficient bearing capacity of urban centers, separation of occupation and housing, stratification, environmental pollution, traffic congestion and so on. The research on the urban spatial expansion of Zhengzhou in the past 30 years will help to adjust the direction of urban construction and construct a livable city. In the light of the research on urban spatial expansion and integration in Zhengzhou in the past 30 years, it is based on the theory of urban space and the theory of spatial integration. The Landsat TM/ETM remote sensing image data of five years from 1988 to 2014 in Zhengzhou were extracted, and the regional spatial evolution process of Zhengzhou in recent 30 years was presented by using ArcGIS software. At the same time, the relevant data of Zhengzhou in recent 30 years were collected, and the quantitative analysis method was used. This paper makes a systematic analysis on four aspects of urban spatial expansion speed, intensity, elasticity and spatial compactness, and probes into the dynamic mechanism of urban spatial expansion in Zhengzhou in the past 30 years by using the method of grey correlation degree analysis. It is found that there are some problems in the urban development of Zhengzhou in the past 30 years: the traditional industrialization leads to a certain degree of decline in the quality of living environment, and the speed of urban spatial expansion is relatively fast. The adjustment speed of industrial layout is out of step with it, the industrial layout is relatively chaotic; the elasticity of urban space is on the large side, which leads to the low efficiency of urban traffic system; the low degree of urban compactness leads to the dispersion of urban spatial layout. In view of the problems existing in the expansion of urban space, we can improve it from the following aspects: purifying the environmental system by increasing the area of green space planning and construction, controlling pollution sources, and improving the industrial layout, Form an industrial structure with one pole and three circles; optimize traffic operation mechanism through rational planning of traffic layout, integration of urban road construction, improvement of public transport system, and enhance the regional connection of functional sub-regions, Reasonable layout of underground space on the ground to integrate urban regional space; pursue the construction of modern culture and heritage of historical culture, through cultural rendering invasion of regional space, to achieve the organic development of the city.
