摘要

产业园区作为城市经济发展的引擎,其时空格局分布的研究对于掌握城市空间结构以及园区可持续发展具有重要意义。为了客观表征产业园的时空分布特征,该文引入彩钢板建筑群数据作为研究产业园区的辅助数据,结合青海省西宁市主城区2005—2020年产业园区部分信息和路网等数据,采用网络核密度分析、标准差椭圆和等扇分析法,长时序探析了西宁市产业园区时空分布特征。研究结果表明: ①2005—2020年西宁市产业园数量持续增长,增长率达73%,其中城北区增长速率最快; ②园区高度聚集区域由单一区域向多区域发展,从彩钢板建筑群的密度变化来看,新增园区多分布在城市边缘,聚集区呈南北交叉带状分布,与城市空间结构吻合; ③产业园区在2005—2020年间均呈现“西北-东南”向分布,集聚方向趋势越来越不明显; ④产业园区的扩张有分阶段分区域发展特征,且扩张强度逐渐减小,园区发展逐渐趋于稳定。研究结果将为西宁市城市化发展研究或园区结构转型等提供客观时空数据支持和方法参考。

Abstract：

Industrial parks are like the engine of urban economic development. Exploring their spatio-temporal distributions holds critical significance for ascertaining urban spatial structures and sustaining the development of industrial parks. To objectively characterize the spatio-temporal distributions of industrial parks, this study employed the data of buildings made of color steel plates as auxiliary data for investigating industrial parks in Xining City, Qinghai Province. Combined with some information and road network data of industrial parks in the main urban area of Xining City from 2005 to 2020, this study delved into the spatio-temporal distributions of industrial parks over a long period in Xining City using network kernel density analysis, standard deviational ellipse, and equal sector analysis. The results show that: ① From 2005 to 2020, industrial parks in Xining City continued to increase at a growth rate of 73%, with the fastest growth rate observed in Chengbei District; ② Highly clustered industrial parks developed from single to multiple zones. Concerning the changes in the density of buildings made of color steel plates, newly built industrial parks were mostly distributed on the urban edge, and the cluster areas exhibited north-south crossing banded distributions, aligning with the urban spatial structure. Additionally, all industrial parks showed a northwest-southeast distribution and a less significant clustering trend from 2005 to 2020; ③ The expansion of industrial parks manifested phased and zonal development, with a gradually decreased expansion intensity, suggesting the tendency of stable development. The results of this study will provide objective spatio-temporal data support and methodology for the urbanization development research or structural transformation of industrial parks in Xining.

Key words： industrial park buildings made of color steel plates spatio-temporal distribution network kernel density
