摘要:

［目的］产业结构与城市空间形态之间存在相互作用关系，以乌鲁木齐市产业结构演替与城市空间形态演变为出发点，定量测度两个系统在城市发展不同阶段的耦合过程及特征。［方法］选取1996年、2002年、2008年和2014年4个年份作为研究时点，以Matlab和SPSS统计分析结果为基础，构建产业结构与城市空间形态耦合评价模型及空间响应模型，针对两个系统的耦合协调度和空间响应指数进行探究。［结果］(1)在乌鲁木齐市城市发展进程中，产业结构对城市空间形态存在明显作用关系。(2)产业结构演替与城市空间形态演变的耦合协调性较强，耦合度介于0.6228～0.7253之间，且呈前期和后期高、中期低的“U”型特征，协调度介于0.9913～0.9995之间，处于中度耦合良好协调水平。(3)城市空间形态对产业结构演替的响应态势表现为前期高、中期和后期低的“L”型特征。［结论］产业结构演替能够推动城市空间形态演变。

Abstract:

There was interaction relationship between industry structure and urban spatial morphology .From industry structure and urban spatial morphology transformations of Urumqi City, this paper quantitatively measured the coupling process and features, on the basis of the statistical analysis results in 1996, 2002, 2008 and 2014, established coupling evaluation model and spatial response model on industry structure and urban spatial morphology using Matlab and SPSS software, and analyzed the coupling coordination degree and spatial response index of both systems. The results showed that: In the urban development process of Urumqi city, there was obvious affection relationship between industry structure and urban spatial morphology. The coupling coordination between industry structure and urban spatial morphology was relatively strong, and the coupling degree was between 0.622 8 and 0.725 3, which showed a "U" type feature with high prophase and anaphase and low metaphase, and the coordination degree was between 0.991 3 and 0.999 5, which was on a fine coordination level of a moderate coupling. The response trend from urban spatial morphology to industry structure transformation showed an "L" type feature with high prophase and low anaphase and metaphase. The industry structure transformation could promote urban spatial morphology.
